Unable to Visualize Mesh

[rpathak38]

I'm trying to add a tree mesh that I found on the unity assets store. Here is an image of the mesh:

There are 160 triangles in total in the mesh. I am adding the mesh like this:

          auto obj = world->addMesh("/home/user/raisim_objs/Trees/birch tree.obj", 1.0, 1.0, "", raisim::COLLISION(63), raisim::COLLISION(63));
          obj->setBodyType(raisim::BodyType::STATIC);
          obj->setAppearance("blue");
          obj->setPosition(5, 5, 5);
          obj->setName("obj");

It seems like the mesh is getting loaded in, but I can't seem to see it correctly just seeing some floating triangles:

What am I doing wrong?
