How to save RGB information when saving obj format

[kaiiyangwei]

I would like to ask you a question, I have successfully converted the point cloud with RGB information to the corresponding mesh through Poisson, and exported the mesh in the form of an obj file, when I open the saved obj file again, the RGB information of the model is lost, is there any way to solve the above problems

OBJ doesn't support per-vertex colors. Only textures (or per-triangle material).

The few formats that support per-vertex colors are PLY and FBX.
