How to optimise collision meshes?

I need a ton of collision meshes in my game, I cant use primitives. And collision meshes are Expensive. Is that true?

1. Do I win performance if I, deactivate the meshes while they are not used?

2. Is it recommendet to load the Collision meshes into the Ressources folder, before usage?

3. Or is it better to instantiate and destroy them every time?

Does anybody have experience or good tips to accomplish this task?

what you can do is to create an other optimized mesh for your collision

 

I edited your post as multiple xxxxxx and ??? has zero place on a programming and development forum. This isn't a stupid chat channel. When asking for help, format your posts professionally.

In answer to your question: Just make the game, then use profiler at end to detect the slow parts. Optimising now is dumb, you have no clue if those are even ever going to slow your game down.

 

Thanks but my character walks finally on this mesh, so It have to be very precise according to the rendered Mesh. So I think the only way is a clever disable enable method.

 

Reading your questions, it reads like you haven't measured anything. You have suspicions and you've heard rumors, but don't have any hard data or experience with it.

Give it a try. Maybe it's not even an issue. Save yourself some work by measuring before cutting.
