Generate Procedural Mesh

Development Programming & Scripting C++

I was noticing that the collision mesh was lagging behind when changed dynamically, I originally thought it was the cooking time as it returns automatically if already cooking a previous change. However after a little experimentation the problem was solved by making the change below. Now the collision generates correctly after updates to the procedural mesh and I haven’t noticed any errors because of it so far.

From:


void UGeneratedMeshComponent::UpdateCollision() {
	if (bPhysicsStateCreated) {
		DestroyPhysicsState();
		UpdateBodySetup();
**		CreatePhysicsState();**
 
                ModelBodySetup->InvalidatePhysicsData();
		ModelBodySetup->CreatePhysicsMeshes();
	}
}

To:


void UGeneratedMeshComponent::UpdateCollision() {
	if (bPhysicsStateCreated) {
		DestroyPhysicsState();
		UpdateBodySetup();

 
                ModelBodySetup->InvalidatePhysicsData();
		ModelBodySetup->CreatePhysicsMeshes();
**		CreatePhysicsState();**
	}
}
