[no] Light from textures

In Doomsday textures can have lighting effects on them, for example, a switch in the off position would actually have green light comming from it) would it be possible to add this in GZDOOM with another lights lump. I would love to see lights on the switches, doors, etc.

And while i'm at it, there is no light for the "Evil Eye" sprite

Probably not. Automatic texture lighting is an incredibly expensive feature. Its only use is cheap 'enhancement' of existing maps. I'd rather make things that can be used by mappers.

I'm glad that you see the mapping community takes percendence. The MARSWAR wad shows off your efforts quite well.

?
It can be used by mappers via a decorlight definition.

Or you can just place a point light in the appropriate position...

Tell me which is easier - manually placing a point light in the required position for every instance of the texture on every map (and moving it countless number of times during level development) or writing a decorlight definition that takes what, 30 seconds?

You make it sound hopelessly more complicated than it actually is. I would think most mappers are happy enough with a meathod that isn't terribly difficult to begin with. I'll concede there could be some ease of use to being able to specify a lighting value for a given texture, but what if the mapper wanted different light levels for the same texture, that appears in several instances in the same map? Would the mapper not be limited there?

True, in which case for that particular texture it makes more sense to use a dynlight object instead of the automatical texture light decorations. By offering both methods the level author can optimise his time without reduced functionality.
