How can I prevent the generation of white background Gaussian during the training process?

[Fiiiiifi]

Hello everyone! I would like to generate 3D Gaussians from a series of 2D images with white backgrounds. However, the white background is also being included in the final ply file when generating the Gaussians. This affects my ability to visualize the Gaussians in the renderer. I was wondering if there is a way to prevent the generation of Gaussians on the white background during the training process?

I have the same situation. how do you solve it

I suggest you could try adding --white_background during training. It sometimes helps!
