However, I train Lego scene with both torch-ngp and instant-ngp at 20000 steps (200 epoch). instant-ngp has a sharper result (green rectangle) while torch-ngp is missing some part of the object (red rectangle). Any tip to improve the quality?
You are right, the rendering quality is not still reproduced as mentioned in #17. Since there are lots of details in the original implementation, it may take some time for me to figure out the reason.
Currently, to improve quality (at the cost of speed), you can remove --cuda_ray, and enlarge --num_steps and --upsample_steps to use the pytorch ray marching.
I appreciate your great work!
