    Question Lighting parts of a UV map???

    Hi Folks.

    Thanks for the continued input about UV maps and overlapping polygons, appreciated. I have a new question now... How do you make parts of a UV map illuminated? Since you're applying just one map/texture to an object, you can't specify specific surface polygons and make them illuminated so how do you do this? For example, a spaceship with windows, I want the windows illuminated so if you view the ship on the side facing darkness, the hull is dark but the windows are bright.

    Not sure about UV map, but if you have a surface/material on the windows, you can illuminate via Surface Editor.
    It's better to have tried and failed, than to have failed to try.

    Make a black and white UV map for the luminousity channel. The windows will glow, then.

    UV maps don't need to be exclusive to one surface or vise versa. You can do as Kryslin says or just give your windows a different name and attribute without the UV map applied.

    Just because it has a UVs it doesn't mean you can't use other projections, for example, using a gradient controlled by a weightmap on the luminosity channel.
