Importing OBJ with vertex colors (instead of texture)

Unity Engine
1

I have an OBJ file that is the result of a 3D scan. It doesn’t have a texture, but rather vertex colors. It looks ok in Meshlab (colors and all). When I import it into unity, and choose the VertexLit shader, it’s still just one color.

Any ideas?

Thanks.

Try exporting the mesh as an FBX file. To my knowledge the OBJ format doesn’t store vertex colors.

From https://en.wikipedia.org/wiki/Wavefront_.obj_file:
Some applications support vertex colors, by putting red, green and blue values after x y and z. The color values range from 0 to 1.[1]

I’ve just run into this today. The OBJ format does support vertex colors, but it appears that Unity’s importer still ignores them.

What’s the proper way to file a bug report or feature request these days?
