Question by J-R-Wood · Dec 12, 2016 at 11:01 PM · colliderfpsperformance optimization

Collider Cost to FPS question

Q1: i want to know if using mesh colliders cost more in terms of FPS and overall performance?

(example: i have a tree in a spherical shape should i use a sphere collider or a mesh collider on the spherically shaped mesh)

N: i am guessing mesh colliders cost a lot more but i'd like to be sure first.

Q2: also since we're on the subject can i use a terrain collider on my land mass i created in blender or should i just use a mesh collider?

Q3: i am making a survival/capture the flag low poly game so if anyone has any other tips to optimize my games performance it would probably be overwhelmingly useful to me.

Thanks in advance.

A1: Yes (see link below)

A2: For terrains, use TerrainCollider instead of MeshCollider because it is more optimized due adaptive LOD.

A3: Check this article: Physics Best Practices

Additional suggestion from me: If you need to use several primitive colliders - attach them all on the root object (do not create additional children object only for collider. Link on my research.
