Model transparency and self illumination doable? (source)

[misterbister]

For adding transparency i use "Alphatest" 1 and it works flawlessly on my model, however I would like to add self illumination in some parts of the texture as well.

The problem is that "alphatest" and "$selfillum" are both using the basetextures Alphachannel.

How can I work around this problem? Is it even doable?

Thanks in advance =).

Forget my stupidity for not reading the post right

you can make a separate map for it afaik

[misterbister]

an envmapmask could help, with a bit of saturation. Look at the lost coast fresco materials for an example of valve's shaders.

I dont understand how i could replace selfillum with an envmapmask? The results should be far from simliar..?

In that case, what should I write instead of $selfillum "1" ?

I cant find any info about it in the source sdk wiki.

I've been trying this before if I remember right. Sadly I couldn't find a way to do it then.

Somehow for this to work you must obviously be able to specify either the transperancy mask or the illumination mask as in the vmt as a separate texture. So far I don't think that's possible but I can be wrong.

If you do find a way however please post what you did

It is possible. Did it with the aimpoint of the M4 in Insurgency so it glows at night/in dark areas.

The texture has to be a "UnlitGeneric" instead of a "VertexLitGeneric"

Thats interesting because technically, UnlitGeneric shouldn't work on models

Thanks alot for the help everyone.

I really appreciate it.
