Need to make the inside part of your screws dark on the diffuse and spec. Add lots of brown/grey grime to the crevices and make that solid black on the spec. Also might want to add some spec-only grime and schmutz on the metal and wood.
Been working on the butcher's knife. Mostly Ive been concentrating on the blade itself. Going for a smooth stone type of feel with the spec, witha teensy bit more punch to help sell it. No spec and with spec The sculpt I did a while back.
I think you'll get different responses for that question. I like to put my spec map in the spec color slot. I've also seen spec maps come in both b/w versions and muted color versions as well.
i like your work but spec is wrong , your spec is almost a wet map, diffuse maps usualy are moore darker and have the whiter area were the light come. with your spec map you optain a wet/ jelly look
Maybe this has been asked but for the environment portion should normals, spec, etc be included? There are no normals or spec in our environment pieces.
i think that at the time i was trying to use landscape splines i was working on a computer that was a bit under recommended hardware specs, so that was likely the major reason it was slow and buggy for me. Haven't done it now that I have machine that's above recommendations
A lot of people just multiply their AO on their spec maps rather than bake the spec with a lighting set-up. Ideally a spec map is a representation of the reflectivity values of a surface. And thats pretty much how it is in high end graphics engines and offline rendering. People put their AO in there to help bring out areas…
