I have a character whose surface texture is to be similar to coal. I figured I would look around for some coal textures to get some inspiration from, but I can’t seem to find any. I realise after some thought that perhaps coal is just really hard to do, it has this difficult mix of opaque and shiny surfaces. See image below. Perhaps I should start from scratch and experiment but the whole lack of coal textures being seems odd. i just cant find anything even half realistic using goolge, the ones I have found are more focused on making a glow effect from fire.
Does anyone have any good examples of coal? I was planning on using Cycles.
Just after some samples for inspiration.
