+### Collision data type
+Flax allows you to generate a convex or a triangle mesh for your collision data.
+
+#### Convex
+A convex mesh is a simplified representation of a 3D object in which all internal angles are less than 180 degrees. This simplification results in a mesh with a uniform shape, and it's particularly well-suited for certain collision scenarios.

+
+#### Triangle mesh
+A triangle mesh is a more detailed representation of a 3D object, consisting of interconnected triangles. This mesh type is capable of accurately representing complex and concave shapes, making it valuable for accurate collisions.
+

+
+As you can see, a triangle mesh offers much more granularity and better represents the mesh but it comes at a cost:
+- More expensive both in terms of memory and calculations.
+- **Cannot** be used with a Rigidbody. This means they can only be used to collide against them.

 ## Create collision data from code
 
 Flax supports creating most of the asset types in Editor using C# scripts (with editor plugins). The same applies to the collision data asset. Here is an example code that bakes the asset:
