VolumeCloud

From Valve Developer Community
Jump to: navigation, search

VolumeCloud is a pixel shader available in all Source Source games. It takes three input materials and creates a cloud effect. It can be applied to models, and requires further testing for compatibility with proxies and parameters.

Volume Cloud applied to various mesh

As the shader is intended to simulate moving cloud cover it does not receive shadows. The effect works best with mostly white, transparent noise but also works with non-transparent textures.

The various texture layers all rotate counter clockwise around the "center" of the UV map. Each layer has additive blending on the others, which allows the depth effect to look seamless with white clouds that layer upon each-other. All three base textures are required to be defined, each one in the sequence rotating at a lower speed.
