PhysX actor limiatation

Hi,

PhysX has limitation to 65535 actors on the scene - which I found pretty troublesome, when I tried to generate large forest today :-/
Could it be resolved somehow?
I'm creating trees dynamically by:

Code:

Game::ObjParamsPtr tree=Game::Objs.ptrRequire("Obj/plant/Tree/0/0.obj");

Matrix m(tree->scale(), Vec(x,y,z));

Game::World.objCreate(*tree, m);

the limit is probably removed in physx 3.0/3.1, not sure

Finally, the limitation was removed in physx 3?

I haven't tested it, but if I remember correctly I didn't encounter any mentions about actor limits in the physx 3, so you can try it out

It would be good to know if this has changed. In the last engine I was using they didn't use PhysX because of this limitation which meant using a crappy physics engine instead... lol

PhysX 3.2.1

Broad Phase
The sdk gracefully handles the case of more than 65536 broadphase pairs and reports a warning that some contacts will be dropped in the event that this limit is exceeded. This affects all platforms except win32/win64/linux/linux64, which support a maximum number of 4294967296 pairs.

Scene Queries
An internal limit of 65536 objects in the scene-query subsytem has been lifted.
