How to optimize Tree Coliders?

Hey guys ! I've added trees in my map (something like 25-30).

When I add the Collision, I have a big fps fall!
How do I optimize it?

Thanks!

 

It depends of how your gameplay is... i mean if its a FPS or TPS you can add a Capsulle collider just on the trunk of the tree. I think the problem is that you are using a mesh collider , isnt it?

 

First of all, thanks for Answer!

Yes, I'am using a Mesh Colider for a perfect Collision
My game type is FPS ^^'

 

With mesh colliders you will get more lag than with capsule collider. And if you leaves are dynamic youll get a lagfest. You can remove that mesh collider and replace it with capsule colliders. You dont need attach the leaves to the collider so... you will be fine puting the capsule collider just on the trunk of the tree.

In fact, you should put box or capsule collider in all colliders that you can. Of course if you cant, use mesh collider but that will generate u more lag .
