Decal System on Skinned Mesh Renderer

hello, I'm working on a FPS project where we need to be able to shot ennemies (anmitated zomby, with skinned mesh renderer). I'm looking for a way to make decals in order to modify texture of those ennemies, i would like to put an impact texture at the hit point of the shot.

I explored many solutions, like the decals classic system, but this is not working properly in runtime. I also saw another solution : calculate mesh point which will receive the new texture, and, get the contact information, instantiate a new mesh at those points with the new texture.

I saw projector solution, but those are modifying all the mesh, not only a part, but i need to modify only a part, at the hit point of my shot.

If someone have information, I would be grateful !

Thanks for the help,

Cédric.
