Gas like effect

(sQynor) #1

Is there a way to make a Gas like effect in a map. Like fog. -> Shader maybe?

I want to make a map where there’s a room filled with gas. Green gas or something.

Thanks in advance.

there was a way to make it… i used an entity with shader key, but i don’t remember details. try to look for pazurmapping website.

Simple, just apply a colored fog shader to a brush. This is one I set up for Praetoria but never used:


textures/praetoria/poison
{
	qer_editorimage textures/praetoria/editor_images/poison.tga
	qer_trans .75
	surfaceparm nolightmap
	surfaceparm trans
	surfaceparm nodraw
	surfaceparm fog
	surfaceparm nonsolid
	surfaceparm noimpact
	surfaceparm nomarks
	cull disable
	q3map_globaltexture
	q3map_surfacelight 0
	fogparms ( 0.35 .5 0.25 ) 512  //(red green blue) distance
	
}

It doesn’t matter what you use for the editor image. The shader doesn’t use a texture. I’ve probably got some extra parameters that I don’t need. I haven’t looked at this shader in a long time. But I remember it had a pukey color. Just adjust the fogparms (red green blue) distance values to your liking.

one of the spyjuice tutorials has color changing fog

Yeah, but the spyjuice fog affects the entire map. He just wants a gas chamber.
By the way, for the fog brush to work, it has to be square or rectangular. Don’t skew the vertex points to make odd shapes.
