Make mesh collider constantly change
OK, I have a model that has a mesh collider but the problem is that when I do an animation on the object the mesh collider doesn't change, so I will like to know how to constantly change the mesh collider so the mesh collider is the same as the mesh
You don't. The performance hit from constantly changing the vertex data in a mesh collider is such that it is never a good idea.
Unity will let you change the mesh used as the collider, but the mesh will not be deformed by animations. It wouldn't be a good idea anyway since you would have to recalculate all sorts of things in Physx for collisions.
Instead use a collection of primitives so that is encapsulates your entire object. Very similar to a ragdoll minus the rigidbodies and joints.
Since there's no access to animated skinned mesh data from the GPU, indeed animating a mesh collider is impossible. (You can manually update a mesh collider from a non-skinned mesh where you change the vertices yourself, but it's extremely slow.)
Good idea, but my game is getting complex and lets I don't want to use what is simple. To have an idea, in my model is necessary to use mesh collider because I want to make it more to real life, that means, if I use a capsule it would not be exactly the same, so in this case I prefer to use meshcollider and make it move with the mesh even if is very slow
Well, since Eric confirmed my initial thoughts, you can't. :(
@Uriel: you don't use a capsule, you use a collection of primitives like Peter G said. Updating a mesh collider in real time is too slow to be usable even if it was possible.
O$$anonymous$$ thanks both Peter and Eric for the clarification and answer, I think I will need to find another substitute of collider
