Today we did get a new nightly build of Blender. You can find the builds as 2.69.1 and the 2.7 test build. These are NOT the same files. One is 76k± and the other is 78k±. I know the 2.7 test build will not load the AvaStar 979 version. I also know it will not correctly export the SL Avatar. See the images.
I also downloaded the Feb 20 build blender-2.69-e7f3424-win64. It too will not install AvaStar 979. Bummer. But, it will install 978. It also does not have a Collada export that works correctly. You get the same skinny avatar mess.
Also, as I try various options in the plain Blender export, I find I am just crashing Blender. So, today is still not the day for Fitted Mesh.
What a downer. May be tomorrow…
