How to get rid of this warning

by BigWings · in Artist Corner · 12/17/2009 (1:03 pm) · 4 replies

Hey all,

I have the following warning on a lot of my objects that I exported as ASE from Blender:

Submaterial has a diffuse map but no UV2 channel for lightmap coordinates. Mapping UV1 and UV2 to be identical.

which is most probably the cause of the following error:
Mesh has lightmap coordinates outside the 0 to 1 range.

I have lightmap uvs on channel 1 and diffuse uvs on channel 2, and are exporting with LMM_
I checked the lightmap uvs and they are not outside of the 0 to 1 range so I suspect it has something to do with the submaterial warning.

Does anyone know how to fix this?

I'm not sure if this will correct it, but you should probably use Diffuse on UV map 1. UV map 2 is the default for lighting.

Switch them and see if it works.

You mean switch them in Blender? I don't think there is any easy way to do that. On top of that, I am using LMM which I believe needs the first uv channel to be lightmap.

Does no-one have any idea?

Lightmaps are coded to work on the 2nd UVW set, other per-pixel effects work on the 1st UVW set. So correct this first and if its still a problem post a follow-up.
