Many games (Doom3-engine, Unreal, Quake3 etc.) and 3D Modelling programs have luminance texture layer for 'local-light' effect on textures. Concept of luminance is simple - it blends on texture using additive blend mode (after lighting get done). The result is some areas on a texture is always lighten (simulating glowing buttons etc.).

Would be cool to see this layer (and luminance power option) along with bump/normal/specular since currently to render _glow layer there is necessary to create new filter or ugly checkbox on current one.

well, if and when we get the arithmetic component, i think this would satisfy your needs.

you can always use a frame and offset to highlight specific areas of a texture if you wish.

VorteX -- yes, a self-illumination channel (and a corresponding texture map) is a good idea. It is already planned for future releases.

The result component being able to perform certain 2D post-processing FX, like said self-illumination additive blend, or even a channel-controlled glow, would be totally sweet. smile:)
