I never really thought something like this could end up so much more confusing than I thought, and I was wondering if anyones done it before tho it is a pretty odd thing, I'm in need of a material and usually I can make my own be it by the deep texture editor or by photography but this material has turned out much more confusing than I thought it would be, I'm trying to make a distant, smooth, concrete the sort you would see where there are great expanses of concrete such as (and as the use in this) an area where the construction of something massive but mobile(as a normal (building) construction site wouldn't require anything like this) object usually a vehicle like say a space shuttle, I know what I'm thinking of but it just doesn't seem to come out right .) anyway I was wondering if maybe theres something really basic I wasn't thinking of or maybe if there was someone else whos done this before, or maybe I just need to work on it a little more(I suppose as far as this material itself goes actual working hasn't happened very much)
