The ultimate guide to prim twisting [UPDATE]


[UPDATE: July 30, 2009] The guide was featured at Massively and the official Second Life blog! Thank you!

[UPDATE: September 12, 2009] I corrected a few mistakes over time (thanks for the head-ups everyone), so if something didn't work for you, try again now :)

Aah, prims. Plywood shapes that magically turn into the most beautiful SL builds. Yes, those prims know how to twist and shout! ... Wait, wh... what?! ... I'm talking about prim twisting - shaping prims into unusual shapes. Prim magic!


We've got sculpties in SL now, which means almost any prim shape is possible without big prim cost. But back then, before sculpties rocked SL, you needed different methods - you needed methods that worked with regular prims. These methods were discovered by early SL residents and sometimes kept secret (the famous one prim double knot for example). I think even the most advanced builder/sculpter should know the basics. You should never underestimate the power of regular prims. That's why I'm giving you this ultimate guide to prim twisting. Every item shown here is only one prim!

    Thank you for such a great resource! Although sculpties are wonderful addition to SL building tools, I have always admired old school builders that can create magic from simple prims. Sometimes I think we overuse sculpts when a little prim torture will do the trick and often look better and make it easier to texture. Great work and thank you for sharing this :)

  2. Uzi Boa on July 28, 2009 at 8:04 AM

    ha... and this is how http://ayumicassini.blogspot.com/ has become my home page... ;)
    I was just on my way to Ivory Tower but you are perfectly on time (this time ;P) to save me.
    Thank you Ayumi for helping me improve my laziness! :)

    Wonderful post! Amazing resiurce and the sheer amount of hard work that you have put into it staggers me - thank you mate! xx

  5. Todd Borst on July 29, 2009 at 11:15 AM

    Thanks for sharing such an useful post Ayumi. This blog is becoming quite a must have resource!

  6. Ghosty on July 29, 2009 at 3:28 PM

    The single most useful builder's article I have ever found. :) ty ty ty ty ty!

    wow yay, ty! :)

  8. Tinsel Silvera on July 29, 2009 at 6:08 PM

    Absolutely amazing! You have just raised my building skills a couple of notches. I am eternally grateful. Thank you.

  11. Ayumi Cassini on July 30, 2009 at 12:27 AM

    Thank you so much, everyone, for wonderful comments. I never expected this tutorial would get so popular but I am very happy you find it useful :) It's been a bit of work, but it was fun ^^ And reading all these comments is sooo motivating.

    I think I owe Massively.com a big thanks for publishing information about this tutorial. I have no idea why it doesn't show up in my 'Links to this post' section. So I'm adding the link here: Second Life torture guide. Thank you!

  12. Alessia Kranfel on July 30, 2009 at 10:14 AM

    Awesome!! I prefer prims, sculpties takes time to rezz for a lot of people. Not all has the last graphic card on market......

  13. Saxon on July 30, 2009 at 5:04 PM

    This is a remarkably elegant and useful guide to coaxing beauty from prims. Truly inspired.

  14. Torley on July 30, 2009 at 5:21 PM

    I need to blog this soon @ http://tr.im/sltnt , it's beautiful.

    Oh, wow! Thank you so much, Torley! I never even dreamed of my name mentioned on official Second Life blog :) This is awesome! I'm so happy :) It's great to know so many people find this tutorial inspiring :)

  17. Corcosman on July 30, 2009 at 7:04 PM

    Very nice post, Ayumi. I see a couple of shapes I was not familiar with yet. Thank you.

    I wonder if any of your readers have a favorite shape not covered in the post? Perhaps they could describe the settings, just as you have.

  18. Daedalus Young on July 30, 2009 at 8:23 PM

    Congrats on making it to the official blog :D
    The 5 faces panel looks awesome, I've only seen 3 faces for text display, if I'm correct, this should save on prims.

  19. Garmin on July 30, 2009 at 9:15 PM

    Sublimissime! Great job and a real artistic taste!
    Thank you for this nice collection,

    Coolness! Thanks for sharing all this!!!

  22. zonjacapalini on July 31, 2009 at 1:25 PM

    Fantastic article, many thanks for posting this! :-)

  23. Thibaud Merlin on July 31, 2009 at 5:40 PM

    Dziękują !

  24. Ayumi Cassini on August 1, 2009 at 1:44 AM

    What a wonderful response! Thanks again, everyone. I love all your comments. I just keep smiling whenever I look here :)

    @Corcosman:
    That's a great idea. I'd love to see some suggestions coming from readers, so if anyone got any interesting shape ideas, feel free to post them ^^

    @Thibaud:
    Yay, that's Polish :)

  25. AntoniusMisfit on August 1, 2009 at 6:13 AM

    I am permanently keeping this blog bookmarked. I was able to shave 30 prims off one of my old prefab creations using this tutorial, and it actually made it look better! To a prim-stingy person like myself, this resource is a godsend! Thank you Ayumi.

  26. Imnotgoing Sideways on August 1, 2009 at 2:36 PM

    Nice! I use a few of these ideas in the low-prim class I teach. Here's another fun one... The 1-prim table lamp: Start with a Tube...

    Rotation Y: 270.00
    Hollow: 95.0
    Twist B:144 | E:144
    Hole Size X:0.70 | Y:0.50
    Profile Cute B:0.00 | E:0.750

    Then pop a clear texture in the cone shaped dent on top to separate the lamp shade. It's one of my favorite shapes in the class. (^_^)y

  27. Chocolate Voom on August 1, 2009 at 8:56 PM

    Thank you so much Ayumi for the excellent tips. Sculpts are wonderful but tweaking basic prim shapes work just as well and IMO, textures look better. This definitely enhances my building skills. Again, many thanks!

  28. + - + Mula + - + on August 2, 2009 at 9:42 AM

    Wowwwww exactly cool!!!
    I've never known that there's the result as sclupty prim.
    Thanks for your kindness to show the way to us.

  29. sage proto on August 3, 2009 at 12:25 PM

    Hi Ayumi.

    Thank you for a wonderful resource.
    I want to teach to the Japanese.
    May I use the photograph?

  30. Jazzman J. on August 5, 2009 at 5:03 PM

    Well done, nice tutorial. Well laid out and explained.

  31. Ayumi Cassini on August 6, 2009 at 12:53 AM

    Wow, the comments are still coming, it's fantastic! ^^ Thanks once again everyone! I love those creations some of you are sending my way, they're awesome. And it's sooo great you guys are inspired by this guide!

    @Antonius:
    Yay, it's great - 30 prims is a lot! I really like it when builders try to reduce the number of prims in their creations. I'm glad I had a little part in it :)

    @Imnotgoing:
    That's a cool shape! Thanks for sharing - it's a new one to me :)

    @sage:
    Sure, feel free to use these pictures in teaching fellow residents! It's always great to share knowledge, and Japanese residents in SL are sooo awesomely creative, I just can't wait to see what they'll create with these shapes!

  32. Syunyou on August 6, 2009 at 12:03 PM

    How wonderful!!
    I came from sage's blog here.
    Your blog was immediately added to my favorite blog list.
    I will be able to challenge again by your favor though I felt the logjam of the object making in SL a little.
    Thank you Ayumi!!

    My wife was one of the very first to achieve the knot, table, double knot and a handful of other wacky tortured prims very soon after she joined in early 2006. She explained to an astonished Linden how she did it: "No one told me it couldn't be done!"

  38. Ayumi Cassini on August 18, 2009 at 1:37 PM

    Hehe, these shapes were amazing to me as well when I first saw them. I joined SL in 2006 but it took me a lot of time to find out how to make the double knot ;)

  48. Shifter Gynoid on November 27, 2009 at 11:48 PM

    What an excellent guide! There's a few things in there that I never knew were possible.

    I'd like to add some texturing info for the "5 faces display panel".

    Let's call the left-most face 1, and the right most face 5. These parameters will need to be set in order to display images evenly and correctly.

    Face 1:
    Repeats per Face, Horizontal = 2.500
    Offset, Horizontal = 0.750

    Face 2: no changes required.

    Face 3:
    Repeats per Face, Horizontal = 16.700, also place a tick in the Horizontal "flip" box.
    Offset, Horizontal = -0.100

    Face 4: no changes required.

    Face 5:
    Repeats per Face, Horizontal = 2.500
    Offset, Horizontal = 0.250

    Hope this helps!

    regards, Shifter.

  49. Ayumi Cassini on December 10, 2009 at 1:50 AM

    Thank you, Circle and Anonymous :)

    @Shifter:
    Thank you for these instructions, Shifter :) I assumed people would figure it out, but I guess it might not be that obvious, so I added information and a link to your comment under the '5 faces display panel' :) I'm sure people will find it helpful!

  50. Wrath Constantine on December 11, 2009 at 11:16 AM

    This is awesome! Since being pointed to this blog about a month ago, I've used these shapes in over a dozen builds. Just used another one tonight in fact. Thankyou for taking the time and effort to share this information with the world. I have since passed on the link to many others and they're just as amazed as I am. Keep it up!

  51. Deson Bowenford on December 11, 2009 at 7:00 PM

    A friend of mine (Wrath Constantine)used one of your creations for a Rocket Nozzle in a build and when I wondered how he did it, he pointed me to your Blog. I've since bookmarked it and have used it in at least 2 other builds of mine. Thank you for this resource.

  52. Ayumi Cassini on December 15, 2009 at 4:27 AM

    Thank you, Wrath and Deson! I'm so glad you use these shapes in your builds! And thank you a lot for letting other people know about this tutorial! :)

  53. Anonymous on December 19, 2009 at 8:36 AM

    Somehow it seems that for face 3 it fits with 15.3 not 16.7 for me, am i doing something wrong?

  54. Alix31 on December 20, 2009 at 11:57 AM

    This taught me so much, and so quickly. Thank you for this guide. It's brilliant.

  55. Shifter Gynoid on December 23, 2009 at 7:22 AM

    Ahh, yes...this prim has slightly different proportions to the one I have. Tweak the texture settings to suit.

  56. Eve kazan on April 16, 2010 at 10:43 PM

    Normally i don't build, beacuse i hate it ^^ , but thanks to you i love :)

  63. Wayfinder Wishbringer on August 1, 2010 at 7:07 PM

    Excellent article. These are shapes I and other builders have long used... but I've seldom seen such excellent shapes gathered in one place (like you said... builders long tended to keep such "trade secrets"). Good for you publishing these where they can be of value to everyone!

    Now, how do you get tortured prims in photoshop (3d) so you can paint directly on them? Instead of screwing around with a ridiculous grid texture and getting now where.

  69. Anonymous on November 10, 2011 at 7:56 PM

    Did you expect to still see interest more than two years after you posted this? :D

    I made a shop light for someones dirty old garage. When I was done, it totaled TWENTY prims >.< My friend has a room at another friend's estate and has a limit of 50 prims >.< ANOTHER friend linked me here and I am very, very glad that she did, even though I haven't found anything useful for that build, yet, I am sure I will find things for plenty of other builds.

    Thank you, Ayumi.

    @KhaliTahnita
    Aww Khali, I never expected such great interest in this guide ^^ I wrote it mostly as a reference for myself and the readers of my blog, but so far it is the most popular blog entry here and brings new people every day. I am very happy it is popular and useful to SL residents!

    These tortured prims are just amazing, & there so usefull, but the best part is that I dont have issues with rendering the shape as I do with sculpts, these will save my prims & my graphic card from TORTURED overworking in sl ty :)

    Thank you! It's the best part of publishing guides like this when people actually find use for the knowledge! ^^

    @Anonymous (November 17)
    I only saw Marketplace listings that actually link here to this blog entry, so I guess it's OK. I wish items like these were free, but on the other hand that person took time to create all the prims I describe here. As long as the credit is there, it's really people's choice whether they want to use their time to create the prims, or use their lindens to purchase the prims.

    @Ancient1 Aeon
    Yay, your comment is very kind! I'm happy I shared what I learned ^^ Thank you!

  75. Mireille on December 24, 2011 at 5:49 PM

    I thank you soooo much for this posting, Ayumi! It is so wonderful to work with the prims. Sculpties are good too, but I really like prim items. :-)
    You are very generous to share this excellent resource, and I know I shall consult it many times.
    Enjoy the holidays - and have a fantastic 2012!

    "We have mesh and sculpties now! Who needs tortured prims?"

    I answer: every good old-school builder that builds for the love of art and for the sake of simple beauty will need tortured prims and a guide such as this one.

    In the Mesh era, this old school builder would not exchange these for any "super high-tech mesh".

    Thank you for making it. it is bookmarked and, since I have a memory of a mosquito, used daily.

  80. Ayumi Cassini on May 4, 2012 at 5:42 PM

    I agree - every creator should know the basics! I'm going to learn how to make mesh stuff in SL though :) But I can't imagine SL without 'traditional' prims, I think they'll always be useful and used in builds.

  81. Mister Acacia on May 4, 2012 at 11:06 PM

    It's nice to see this kind of contribution to the virtual community. Being able to massage a prim into something whimsical or beautiful is a talent that should never be supplanted by sculpt or mesh. I am inspired to reduce prim count by replacing some of my mesh and sculpted objects with twisted prims, saving land impact and vastly improving rez time.

    Best regards,
    Mister

  82. Ayumi Cassini on May 7, 2012 at 8:33 PM

    I am happy the guide was inspiring to you! ^^

  83. Vincentsedubun on August 17, 2012 at 10:27 PM

    im happy this guide exists! but i am wondering, does you know how to make 4 holes/6 holes in a cube ? like a hole on each side. Normally you can only make 2 (1 that has 2 ways) with the hollow option in the object tab?

  84. Venus Aldrich on August 20, 2012 at 10:22 AM

    Do not know if I really had to post this to your blog, Ayumi, but as gratitude for the fact that I have improved my building knowledge by reading it, decided to do it. An important building information is took out in your blog, and maybe this will give us more courrage in playing with the settings of those SL cubes. We can see here what interesting shapes we can get. I am using these settings now, combined with others, to create my objects, and the result is really nice. Will keep improving... Wish you a "Happy building", everyone!

    Very helpfull page was posted on Builders Brewery in chat. The Flower 1 size on E shows E=360 but i had to use E=-360 to make work. Really cool when it happens and appears :)

    Imagine my surprise when I sent a simple question about a prim to designer Kamherra Albatros (who as it turned out subscribes to the PayItForward philosophy here in SL) only to have her reply promptly, give me a full perm copy of one of her tortured prims to study AND a link to this awesome guide.
    Thank you Ayumi for posting this. Going to have so much fun now that I'm armed with a key to arcane knowledge. This guide is akin to getting a cheat sheet on how to make flame fractals using Apophysis!

    OK, here is a challenge for you! I have a path on my sim that goes up a hill, then turns left 90 degrees and levels out at the same time. Needless to say, it is not a pretty sight, using multiple prims. Is this even possible with a single prim?

  89. King Jisper Darkfold on November 8, 2012 at 9:32 AM

    Was pointed to this guide nearly a year ago by one of my SL clan members, and in turn have pointed others interested in learning how to build toward this resource. It's a fantastic one -- If you have use of other shapes - try making a ramp from a twisted cylinder. I don't have exact numbers, but do a 5 hollow for a center post, twist from -180 to 180 (or the reverse to go the other way) and pathcut to as small as it will go. gives you a neat little spiral ramp. of course adjusting the twist can make a difference in slope. to complete the "tower" for it just copy the cylinder, untwist, hollow and reverse pathcut until you have the right size opening.

  90. Mister Acacia on November 18, 2012 at 4:15 AM

    Anonymous, I'm been pondering your ramp for some time, and I haven't found a way to torture a prim to do what you need with just one prim. I would use a cylinder on its side to level the ramp (pathcut and hollow to hide the unused bits as needed), then another cylinder upright with Z equal to your path prim height, path cut to a quarter circle, to turn the path.

    But I'm far from the expert here.

  94. Xandra McKnight on August 18, 2014 at 3:33 AM

    Don't forget the trick of twisting a cube 45 degrees in the same direction on both ends. You get a cube that can be stretched from the corners instead of the sides. Learned that trick at the Ivory Tower Library of Primatives!

  95. Tatiana Cheng on February 15, 2015 at 10:39 PM

    thank you for posting this, i've been having fun learning how to make these shapes and see ones i'll be able to use in my jewelry designs. I did notice however that on the tiny cylinder that the Z size needed to be 1.000 and not .010 otherwise it looks like a flat circle. Still a great reference and starting point for any builder. :)

  96. Ayumi Cassini on February 17, 2016 at 12:58 PM

    Well spotted, Tatiana, thanks! :) For the shape in the picture I actually used Z size of 0.100. I corrected the mistake.

  97. Lord DoomRater on March 24, 2016 at 10:08 PM

    I have a shape that should appear on this page: Sword Blade.
    Rez a Cube
    Set Size to x=0.15, y=0.05, z=1.0
    Set Twist to B=45, E=45

    For a Sword tip, set taper to x=1.0, y=1.0, and adjust the z to fit. You can even set the taper to anything in between on the blade as long as x and y match to get all sorts of tapered blades.

  98. Unknown on April 11, 2016 at 12:13 PM

    Thank you so much for sharing your knowledge, it means so much & now a noob builder like me can also twist prims. Can someone tell me how to texture the mirror please.
