Say I have multiple meshes in one model, exactly how do I make it so each mesh has its own bone (NOT ragdoll stuff, just arbitrary bones that do nothing)? I tried using the skin modifier but I must be doing it wrong because the bones don't exist ingame.
These are automatically collecting in the export process from skin modifiers. The most common reason that these are missing is that the model's $staticprop setting is turned on. When on, WW skips all bones.
