What Avastar is
Avastar is a paid Blender add-on for creating avatars, clothing, animations, and rigged content for Second Life and OpenSim. It connects skeletons, shapes, weights, poses, animations, and export settings within Blender. Fitting tools use shape sliders, developer kits, and Fitted Mesh weighting to adapt clothing and attachments. Rigging features support mesh binding, weight transfer, copying, mirroring, inspection, cleanup, joint positions, bone groups, and human or non-human rigs. Avastar supports Second Life legacy deform, attachment, Fitted Mesh volume, and Bento bones. Creators can pose characters, transfer motion, and export animations. Export formats include Collada, Second Life .anim, BVH, and simplified glTF for rigged content; the Collada exporter checks meshes and rejects exports when a checked rule fails. Releases target particular Blender generations, so compatibility should be checked before installation. Version 4 documentation is still being updated, with some sections reflecting version 3. Avalab says users retain rights to creations made with its tools, while the software packages themselves cannot be redistributed unless permitted.
