Fog Shader Questions


Undertaker

Recommended Posts

Hello everybody,

I'm new to fog shaders and I had a couple of questions :

1/ How do I create a layered fog shader ? For example a ground fog, density fading on Y axis mixed with a noise to randomize the effect a little bit . I believe I have to play with VOPs, as I couldn't find it in VEX standard library.

2/ I would like to create a more sophisticated Image 3D Fog shader, for example add some turbulence, and other effects, do I also have to use VOPs ?

I believe these questions have quite the same answer, basicaly I just need some help on the methodology to create a Fog shader. :huh:

thanks in advance.

Julien
