Is it normal that the output ply after compression and decompression is grayscale and has no color after the training is completed? Even after modifying the shdegree, there is still no color with decompressed PLYs.

Hi,
If you want to get the ply after compression and decompression, please use the compress_ckpt_2_image.py, instead of the compress_ckpt_2_image_precompute.py, as we perform precompute for color and other attributes for efficiency when playing in the viewer.

hello, I also encountered the same problem. I noticed that "checkpoint/interation_N/*.ply" is already saved as gray format, and your suggested solution still did not solve the problem.

Hi, I'm not sure what the "gray format" means. Could you send me a .ply file and let me check it out? And what dataset are you using for training?

I've sent the detailed training results to the email address on your homepage. Thank you very much！！
