Hello !!!! I need help to color my meshes that are around a bone! Thats it... The 3d model contains a bone and id want to apply an animation coloring the part of the 3d model in wich a specific bone make part...... PLEACE HELP

In a skinned mesh, every vertex stores which bones affect it and by how much (skinIndex + skinWeight), so you just check if a vertex is influenced by your chosen bone and then color it differently—this way, the colored area follows the bone automatically during animation.

thanks

the problem is that once i identify these skinned meshes affected, whne i apply the transparency the entire model gets the coloring animation, not just the part of the model i want

You need to tell your shader/material where you want the alpha to take affect. For this, you can use an Alpha map Texture or store alpha map/mask within vertex colors which you can control via a shader

thanks!

the issue is that I need to apply this to generic 3d models of people that may not have this knowledge about 3D technologies.

from a regular model imported, i gotta be able to identify its part based on its skeleton/bones
