Hello,

Instead of a light entity which emits lighting from a point, I want to create a shader for an area light emitting.
So this shader would be invisible and emit light.

I've tried (randomly) that but I've got the missing texture in game instead of invisible one:

textures/test/lightarea
{
    qer_editorimage "textures/common/white.jpg"
    qer_trans 0.2
    q3map_surfaceLight 400
    q3map_lightSubdivide 512
    surfaceparm nolightmap
    surfaceparm nonsolid
    surfaceparm nomarks
    surfaceparm noimpact
    surfaceparm detail
}

Do you know how I can fix this?

I don't have the common.shader handy to check but I think "surfaceparm nodraw" will do what you want.

With nodraw param, the brush is invisible but there is no lighting anymore.

You're not specifying a texture to use for your shader, that's why you get the 'missing texture' texture. You can use a completely white texture with blendfunc filter to make it invisible.

Yeah, it works. Thank you :)

I think there's another way of doing this, Gsigms and i discussed it a while ago.
But can't remember how it's done anymore, ask him.

nah. 3 times (as described in my OP link) should be good to go. :) (implied that you dont find a bug afterwards....)
also there are quite some compile scripts out there. some even with GUIs and stuff. i've written my own things in batch, so that it automatically does an backup and cleanup of the .map file, a full compile and a bsp.exe run to integrate the surface sounds.

Also, radiant (i used to use 1.5) has all those options built it. (it might not have the most recent version of q3map2, but that actually doesnt matter) You could just do check out the built menu there. (if i recall correctly it even has a final compile built button, which does all necessary things; you could also add/customize built options)
