No collision between Actors, why?

the two actor are all created by TriangleMesh(Shape), by following code:



 NxOgre::Resources::Mesh* mymesh = libFlour::BakeTriangleMesh(mSceneMgr, "robot.mesh");

   NxOgre::Actor* a = mScene->createBody<Body>("robotmesh", new NxOgre::TriangleMesh(mymesh), NxOgre::Pose(0,0,0), ActorParams("gravity:yes"));



 NxOgre::Resources::Mesh* mymesh2 = libFlour::BakeTriangleMesh(mSceneMgr, "ground.mesh");

   NxOgre::Actor* a2 = mScene->createBody<Body>("robotmesh", new NxOgre::TriangleMesh(mymesh2), NxOgre::Pose(0,0,0), "static: yes");

but no collision between them , if changing Actor "a" with Convex(or cube...), it's all right ,
why?

TriangleMeshes don't collide with each other, and you can't use TriangleMeshes in anything but StaticGeometries.

It's all in the PhysX SDK documentation.

thanks!

you mean that, if i create a car, the car body shape can not the same as its real shape ? only can be created by cube, capsule , convex,..... ?

Basically yes, but you can use more than one shape in an Actor/Body to make up the parts of the car.
