Adding multiple decals to a 3d model.

Unity Engine
1

Hi All,

I have a spaceship which is a 3d model and I want to add visible damage to it based on the point it was hit. I have a collider on it to determine the hitpoint, but I do not know what the best method is to add multiple decals on a specific local coordinate. I have looked for projectors, but those seem to be only able to project an entire texture onto a 3d model at one position, and I want multple smaller ones on different locations.

Does anyone have a suggestion on how to approach this problem? Do I just a masking shader or did I miss something about how projectors work?

Edit: I am building a game for IOS.

This is not a simple problem, and Unity does not offer any good built-in solution. You could try Edelweiss’ decal system, which is very good.
