PhysX maximum contact pairs


I am new in PhysX and planning to apply PhysX to engineering simulations. However, I got error message “reached maximum contact pairs” when I used around 30,000 rigid boxes. So, I would like to know is there anyway to increase maximum contact pairs in my scene.

Actually, I tried to generate a scene with “sceneDesc.maxNbContactDataBlocks = PX_MAX_U32” (, but I got same error message. Am I missing something?
