GeneratePhysicRepresentationForMesh causing slow down

[josemendez]

Hi there

I've got a simulation where we create Obi Cloth balloons which move around the screen. However, whenever we spawn a new bubble and use GeneratePhysicRepresentationForMesh we're getting significant slow down. 

For reference we call:  

Code:

yield return balloon.GetComponent<ObiCloth>().GeneratePhysicRepresentationForMesh();

inside the spawn coroutine. 

I've tried threading the code, but GeneratePhysicRepresentationForMesh needs to be on the main thread. Is there a way it is meant to be used which means it has a minimal performance hit?

Hi!

GeneratePhysicRepresentationForMesh is a coroutine that returns a completion percentage. As such, at runtime it is supposed to be used together with some sort of "loading bar" or UI feedback. It is a very resource intensive process that can take quite a while to get done.

If you want to create balloons at runtime, best approach is to either have them pre-generated as prefabs, or if you need to use procedural generation, generate one (or several variations) at the beginning of your scene, then instantiate copies of them.
