Second Life Mesh Clothes Blender 2.6 Setup 2012 Tutorial

by

Update: 1/2014 – See: Fitted Mesh Base Avatar Files for an update on available files for use in clothes making.

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: .

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 I’ve updated it several times, but it is still out of date and awkward in some places.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.

No Room to Sit

The Problem

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.

Beginner’s Second Life Mesh Tutorial

by

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.

#SL Removing Scripts from Stuff

by

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.

Visit the Second Life® Script Library to see what they have stashed away in there.

#SL Blender Clothes Retopology

by

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.

Direct Delivery Launches

by

The Lindens have enabled Direct Delivery on the main grid today. There is also a nice new shiny blog post creatively titled: Direct Delivery Launches Today.

The post has links to Wiki pages with more information and a Torley Linden video, Yay! Torley! Titled: Direct Delivery Essentials.

I am one that believes in avoiding the rush and never being first… even if there is a virgin involved. First is dangerous and full of surprises.

UPDATE: Getting your Merchant’s Outbox working is trick. To get the Received Items folder visit the Market Place and get the Direct Delivery Bear. The Received Items folder will appear when it arrives. Actually buying anything that is Direct Delivery ready will cause your Received Items folder to appear.

Getting the opposite side of the coin working is more complex. Some are saying log in and out of SL and it will start working. (Me->Merchant Outbox…) But, that has not worked for many of us. The in-world commerce group is flooded with people asking, ‘WTF?’

Some are recommending logging out of and into the Market Place then logging out of and into of Second Life. A number of people are saying it works for them. I tried it and it worked for me. \o/

UPDATE: For those moving things to the new DD Market Place… when you make a folder to place an existing product into DD, the name must match the product name exactly to auto-associate. Otherwise, you must manually associate the new DD item with the existing Magic Box item.
