In April I posted an article on retopologizing (like that is a word – redoing the topology of) mesh objects in Blender. See: #SL Blender Clothes Retopology. In Blender 2.62 I kept having problems getting the method to work. I think it was more me than Blender that was the problem. Whatever… today a decided to figure it out.
#1 Getting Surface Snap to Work - Click to Enlarge
I plan to do more tutorials. One of the things I want to do is work with weight painting to see if I can make skirts that work better than what we have. The current mesh mini-skirts show it all when one sits down. I don’t think it has to be that way. Now I need a well made skirt to work with. So, I’m studying 3D modeling. One of the things modelers deal with is redoing the topology of high polygon into low polygon models. Using the tools built into blender can make changing the topology much easier.
Update: 11/2013 – Fitted Mesh, previously the Alternate method or Liquid Mesh, is now the approved method for making mesh clothes that conform to the avatar’s shape. See: Fitted Mesh.
UPDATE: 6-25-2012 – Things may drastically change. See:Alternative to the Deformer. 4/2013 – Several designers are using the alternative methods now. Linden Lab is recommending avoiding use of those non-supported features. The Lab may make changes that break the feature some day.
UPDATE:Rewritten 5/24/2012 for the Bone Weights problem.
My previous article on setting up Blender for making mesh clothes (Second Life Mesh Clothing Tutorial) was written in September 2011, eight months ago. I’ve updated it several times, but it is still out of date and awkward in some places. Blender is now at 2.63+ and has BMesh. Photoshop is up to CS6. The Mesh Deformer is close to being completed. We have a self correcting Bone Weight Copy add-on and more. So, lots of stuff has changed as of May 20, 2012. So, it’s time for a new version of the tutorial.
#1 The Default Avatar Shapes (Kinda funny)
A few days after I wrote this tutorial I found a problem with the file. The Paint and Weight Paint Brushes were messed up. How we create the files has to change. So, I’ve rewritten this tutorial again. This is the revised version. It replaces the previous one.
In this tutorial I’ll assume you are new to making mesh clothes. I’ll also assume you have some knowledge of Blender and Photoshop. I’ll be using only Blender 2.63a in this tutorial. I will also omit the import to Second Life as this Tutorial is already over 9,000 words. Plus, there are lots of tutorials on the Second Life mesh import.
I suspect most of us have seen this ‘No Room’ message at one time of another. When I first ran into it I wondered how they did that. Later I wondered about why they did that. I asked around and never got an answer for how or that it could be deliberate. I asked in the College of Scripting and Music Science in-world group. I explored the Ivory Tower Library of Primitive. I read forum threads. I never got a good answer.
There are two similar messages:
No room to sit here, try another spot
There is no suitable surface to sit on, try another spot.
Sit Tests - Click for larger image
I suspect most of us thought these a simple annoyance. Playing in combat regions and wanting to build defendable fortresses I realized the “No room to sit here, try another spot” thing could help with defenses, if I could just figure out how to make it work on demand. Try as I might, I couldn’t figure it out.
Gaia Clary has 3 new tutorials out from a new series of mesh tutorials for Second Life® users new to mesh. This tutorial series starts with the basics of mesh and defines what vertices, edges, faces, polygons, and quads are. I think it is a great series for anyone considering building with mesh and unfamiliar with 3D modeling.
New Machinimatrix Tutorials
There are 10 videos on the new Mesh Path page at Machinimatrix.org. All but the 3 Coffee Cup tutorials I have seen before. Some use Blender 2.49 and other various versions up to Blender 2.62. The new Coffee Cup series uses 2.62.
It may be subtle but, the Coffee Cup tutorials are about 3D modeling concepts more than they are about using Blender. Additionally, the overall focus is about modeling for Second Life. The other 7 video tutorials take one farther into modeling for Second Life.
I have some older accessories in my inventory that have color changing or sizing scripts. They do not have a Remove or Delete Scripts feature. Some of the items have hundreds of scripts in them. Fortunately they are Modify-OK so I can remove the scripts. The challenge is how to get them out and not die from repetitive script deletion syndrome.
I found a way! Here is a handy tutorial for removing scripts from jewelry, shoes, hair, and whatever.
Script Library
You may know about the script library, if not you should. It provides scripts to solve all sorts of common problems. The best part is all the scripts are free for you to copy and use.
In my reading I came across an excellent video on how to simplify models. Masami Kuramoto posted the information in the SL Forum. Video Tutorial on Retopology in Blender. 14 minutes of excellent information.

If you are making Second Life clothes, you need to see this tutorial.
The first tip ralusek provides stumped me. He is not using a key/click display and he went fast enough I missed it even after rewinding three times. I couldn’t get it to work. It is just too handy not to figure out.
