Hi. This is the base of the new scene I'm working on (another HDRI fake). I thought the mats looked interesting, that's why I'm posting here this early stage. The ball uses AgentS suggestions on scratched metal. It's a basic reflective metal texture with bump driven by three different pictures in channels A, B and C. Specularity color provided the iridescence. The ground is a Lemog photographic texture with a cloud texture in channel B to drive reflection and specularity in the hope to achieve a "spotty-wet" feeling. S.
