I’m pretty new to Blender, so forgive me if there’s a simple solution to my problem. I have .pmd models and I can import them fine and see all their textures. The problem lies when I try to add bones to them. I make entire skeletons and try to add automatic weights but it doesn’t work. It says Bone Heat Weighting Failed. My friend suggested removing doubles, but that doesn’t work. How may I find a solution to this problem?
