Title: Snow/blizzard Shader
Post by: A Spork on January 15, 2011, 09:05:14 pm

So, basically i'm creating a smallish outside section for Thule, and I want it to look like its Blizzarding(or at least snowing).
I tried using that rain shader found here (http://tremulous.net/forum/index.php?topic=9920.0), and just altering the texture to look more like snow, but that doesnt work(Just get a box that looks like the texture is just painted on it, but its nonsolid)
I've also tried modifying a moving water shader with fog, but that just goes notex.


Can anyone give me a hand with this?

Well, there is nice snow particle system in niveus, is that fine?

Well withthe size of the area a particle system would absolutely murder the FPS...

You can try use few patch meshes instead of brushes.
Or (may be) you have problems in shader. Seems you used 'snow' image without transparency or something.

The following blendFunc

Code: [Select]

blendFunc GL_ONE GL_ONE...will definitely produce transparency results.

Animate textures on planes(with transparency layer) and add some random movement for distance where you can't see it up close.
The planes would have an image of snow falling and would save FPS theoretically speaking.
