When I rendering the example obj fiel, everything is fine. But if I trying to render my obj file, it just showing nothing. No warring, no error message. Here is my obj, mtl,and png file.

Could anyone tell me what happend?

I also encountered this problem and I have seen some answers like using the default camera pose. I can render my obj file well at default camera pose, but I'm curious about how to get some suitable camera pose parameters for rendering a new view color and depth map? hope you can help @mmatl, thanks~

I make a stupid misstake,my obj is to huge and camera is too close,so I move my camera backward,it solve my problem. I'm not sure what you mean. Maybe you can try to setting "zfar" and "znear". This is my camera setting OrthographicCamera(xmag=200.0, ymag=200.0, zfar=1000.0,znear=0.1)

@swallow00001 scene.add() can not only add camera's intrinsic but also camera pose, what I want to know is how to add a proper camera pose so that I can use the mesh combined with the camera intrinsic and extrinsic parameters to offscreenRender the color and depth map.
