Our graphical pipeline for the Awareon project now revolves around a handful of tools: ProBuilder for level geometry, nDo2 for texture “painting”, dDo for specular + gloss and Shader Forge for custom shaders + materials.
The idea here is to keep things clean and not get too crazy: Generating textures automagically whenever possible. This should hopefully cover most of the level-design content.
I just installed Shader Forge earlier today, so I’m going to be poking around in it on my Twitch stream for the next hour or so and probably again later in the evening. http://www.twitch.tv/rogdolos
