DebugDrawer, only draw certain meshes?

Hello,

Is there a way to set Bullet's debug drawer to only draw certain meshes? I have a terrain object that uses a height field collision shape, but the mesh is very fine, so the drawer ends up drawing millions of triangles and then lags my entire application. I only want the drawer to draw my small rigid bodies that are moving around a lot. I tried doing a search but I couldn't find anything useful.

Any assistance would be appreciated.

Thanks,
Gavin

You may try:

Code:

terrainBody->setCollisionFlags(terrainBody->getCollisionFlags()|CF_DISABLE_VISUALIZE_OBJECT);   // Disable debug drawing

alternatively, if you are bothered by the normals but want to keep the wireframe try the 1st patch in:

/selfpromotion ;P

edit: the 3rd patch also shows bounding boxes for child-shapes in compound shapes, neat for both debugging and debug-drawing
