Hello, wonder3d is a great project! When I loaded objaverse data set through blenderproc to make multi-view images, how to set the internal parameters of the camera, fx,fy, cx, cy. And the cam2world matrix? I solved the attitude matrix by loading the cam2world matrix with 6 perspectives provided by you, and then applied it. The perspective images i get is quite different from you.

Hello, have you solved the problem? I also want to know the intrinsic matrix for reconstruction, i can't find it in the code.

We use orthogonal camera, there are no fx fy.

@xxlong0 @flamehaze1115 Hi, since Wonder3D used orthogonal camera for rendering, there should be a ortho_scale parameter for controllong the scale of the camera view right? How did you set it?
