I train and render with my own dataset. What is the possible problem?

Thank you for your advice! I have adjusted the depth_trunc accroding to the scene. The [Open3D WARNING] Write PLY failed: mesh has 0 vertices is missed. But the error still occurs:

Should I adjust the value of n_cluster?

hbb1 commented 3 weeks ago

Not related to the post-processing step.

The [Open3D WARNING] Write PLY failed: mesh has 0 vertices is missed.

It suggests that you don't effective adjust the depth_trunc and the mesh still has 0 vertices. You may estimate the depth range according to the values of the depth-map or according to the the camera extent.
