Thanks for your comments and info ! The tarnished bronze is on my list, and the metal grate ... I don't see exactly what it means . But i'll do a floor : the kind of things you can find in a building site . Most of the shaders will be procedural, though some fairly complex computer-generated textures will be used for some of them (wire fence,chainmail,floor) . I'm working on optimizing the shaders to make them easily editable . And i think some of them will be splitted in additionnal mixes ( rust,dust,dirt...) with "reference shader" channels . litst litst.@freesbee.fr
