Sounds interesting. & Petunia, I believe lucstef was propsing that his app would indeed create a copy of one of your original maps and call it IRIS (for example) and the model would use this for it's iris map. To change one, his app would overwrite just the temp map "IRIS", not your original map. lucstef - If the material mapping names are generic, & the same for every figure, what do you do with scenes with multiiple characters using different maps? & wouldn't you need to reassign the old maps everytime you reload the scene?
