Found a way how to do it.
When two or more additive texture mode models are in you screen there come light.
example image :
So if there are 4-6 additive texture models in back
there come full light style.
( Tested by models )
Tested image.
Like you see , all ohter models are dark but that fog additive texture mode model is hightlight.
( I changed sky too black so you can see better this thing. )
i upload fog model for example.
PS: Model by me.
Model is big so i dont know that you see this in model viewer
but, if you are mapper then you can use it to test or what ever.
if you need to use this model on your maps, feel free to use it.
so, if you want to make player model what is hight light level in dark
you just need to copy old mesh , paste it , make origin same as old mesh,
scale it 1,001 point. then again 4 or 5 times
and copy old textures, rename it, and use it for copied mesh then make that copied textures to additive texture mode.
so yeah, if someone also want to know how to hight light models then here it is.
Only way in hl engine.
I dont really need it anymore because i moved in cs: source now.
thank you alliedmods.net to tryng help me for that!
