They all look realistic to me.. but I can't believe anyone would be able to beat the procedural rock materials already in vue...using texture maps always eats up valuable resources. Imagine is someone had 1 million rocks in a scene all using this texture.

To be successful in the marketplace, you have to provide something not already available, that really stands out and is desirable. Since outstanding procedural rock textures are always included in every version of vue, I can't see a market for these at all, unless I'm missing something?

Way too many people take way too many things way too seriously.
