pixel perfect collision ?

Is there any possible way to make a 3d object have pixel perfect collision ? I have unusually shaped objects and such and want my character to collide perfectly with these objects.

I assume your talking about a 2d game because your saying pixels instead of vertexes? If it is 3D you can use Mesh colliders but they are heavy to process. If its 2 D you can assemble box colliders to mimic the shape of your object, if you are using animated sprites … I am not sure.
