Electric Image Universe allows for layers to be placed on objects. Layers can be grime, grit, basic texture, paint pealing, etc. I think that with some hard work on the learning curve, the node system introduced in P5 may come close to simulating that. Pandromeda uses a node type of texturing with layers. So does Terragen. I think we need some really good and in depth tuts on this type of texturing. When I get a chance, I'll check out some of the Pandromeda tutorials by Calyxa and others on texturing and see if the concepts can be applied to P5. I think so.
