11.5 LightWave - Creating ground fog using the new fog texture feature
di Kevin Phillips
Along with all the big ticket items that were added in LightWave 11.5 came a lot of smaller enhancements to existing tools. One in particular is the new option to apply textures to the fog color.

In this quick introduction to this feature, I use the texture editor to create a very fast-rendering ground fog pass. While there are already ground fog tools available, this approach not only renders super-fast, but offers an incredible amount of creative potential that goes beyond just simple effects such as this.
