This is the only way I know of combining multiple UV maps into a single map...

You can rebake one of the textures to the UV map the other one uses, so in the end both will use a single UV channel.

As far as I know none of the model formats Source uses at all support multiple UV channels, so I'm afraid there's no proper way around this.

yeah now that you say it, why didnt i think of this

I have a model from SWBF2 which uses one uv maps for the diffuse map and another one for the normal map, since source doesnt support multiple uv maps im asking if someone knows a way around that
