thank you for this nice work. when i test my data , i find my ply will render empty blocks, and mesh is also.so can you give me some advcies to solve this problems?
it may be caused by low alpha? or some reason?

I wonder if it was caused by the specular highlight?

thank your reply, I found that the reason for this phenomenon may be that our scene lighting caused the surface to be nearly transparent, so in 2dgs, by adjusting which parameters, we can reconstruct this surface as much as possible

Hi, which depth mode did you use? From my experience, using mean depth for normal consistency alleviates this phenomena. You may also increase normal weight to let the surface smoother or adopt some coarse-to-fine strategies to achieve some balance. Any way, it is a little bit tricky.
