The ply output is missing the color texture Below is an image of the exported ply (of garden splat) after loading it into a separate unity scene image

My rendering scene cannot be opened and keeps displaying an error message.The following is the content of the error: 1.IndexOutOfRangeException: Invalid kernelIndex (1) passed, must be non-negative less than 19.

Finally,how can these problems be solved?

PLY export does not export "a mesh", it exports the gaussian splat back into the file. This is meant for saving the 3DGS "edits".
