I try to use JMonkey engine (JME3) to create a scene. In the default project I use the default camera. When I render 3D models from uploaded .obj sources the engine starts to cut the objects too early when the camera nears to the object. I think I need to make smaller the distance between the real camera place and the place from which the engine starts to look into the inside volume of the model. But I can not understand which variable controls this distance. I show the example to see how long the distance between the camera and the stairs by default.
How can I change the distance to the cutting plane?
