Poor rendering results question

Hi! Thank you for your excellent work on 3DGS segmentation! But I'm currently facing some issues with the 3D segmentation step.

I currently have a pre-trained model, but it was obtained not through the original 3DGS method but through another 3DGS method. The model rendered well in that methods, but the rendering results were poor after using the SAGA render function. This results in 3D segmentation being ineffective.

My render result:

SAGA render result:

I'm not quite sure if this issue is caused by the diff-gaussian-rasterization module. Can you give me some advice? Thank you for your work！

Hi, sorry for the late response. I guess there are some problem with the camera poses. You need to align it with the original 3D-GS requirements (I'm not sure the concrete problem you facing). Can you directly use the original 3D-GS to reproduce the rendering? If so, SAGA will work well.
