I actually just finished writing a version of the Vertex Animation script for blender! Right now it only has the animated mesh functionality. Basically you select all the animated meshes you want in the effect and push a button and it spits out a single mesh and two textures to export. Your total vertex count can’t be higher than 8192 and it eats your 2nd UV channel, but any other UVs will be added to the export mesh. For a crowd you might do like a couple different groups of people. Then you can also offset their animation in the material and particle system. If you’re interested I’m going to make a post soon. I just don’t know the best way to distribute it. I don’t have a GitHub or anything. Hopefully it will have support for key framed meshes soon. Also I plan on making a full suite of tools with something like Pivot Painter too if possible.
