I imported an OBJ file of a model made with Reality Capture, and I’d like to try some lighting options in Rhino
The issue is that the object is always bright, even with no lighting, contrary to native Rhino objects (textured or not).
I thought maybe it was because of the vertex colors, but other than using “RebuildMesh” which will also erase my texture, I don’t know how to do that and couldn’t find any useful info on how to do it.
In the Rendered display mode settings check Shade vertex colors:
Because the mesh has vertex colors those essentially override in Rendered mode. To have them participate in lighting you must therefor have Shade vertex colors enabled.

Thanks !
And if I wanted to keep the texture but loose the vertex colors (which I don’t need), how would I go about and do that ?
Something telles me that the “Shade vertex color” thing is causing this disgusting ripple effect I get when I introduce a point light :
Moreover, something seems to be broken with the display modes.
I copy the standard “Rendered” mode, but it doesn’t want to keep the name I’m giving it.
Even the options don’t stick…
Hi @Nasty_booger (

Use -RebuildMesh (no pre-selection) and make sure that you set PreserveTextureCoordinates=Yes.

Ahhh ! That’s it ! Thanks.
I forgot that pre-selection stripped us of the rights to get some options for certain commands, and for some obscure reason.
