Mesh collider polygon reduction

Questions & Answers
1

Hello,
so i have recently created a car in blender which has around 60k faces.
I have imported it into the unity and when i trie to apply mesh collider (i need convex and i know differences between convex and not convex) im getting error that i have many polygons.

My question is if there is any way of reducing or recalculating polygons except reducing faces in blender, becouse then my car looks horribly.

Don’t use the same mesh for collision as you do for rendering. In blender, block out the basic car shape and export that as a separate mesh. Generate colliders for this new mesh, and then drag it onto the MeshCollider component of the car. That way you get the best of both worlds.
