d1ver - Steel bluing is a form of oxidation. oxidation = non-metal. as for baking in lighting, you're absolutely fundamentally wrong. baking in lighting information defeats the purpose of PBR (which is, to make things consistent in all lighting conditions), it also removes control from both you as the artist, and from the…
@Stevston89 - For the sake of myself, as well as others who are new to PBR/PBT, could you elaborate on or perhaps even make a small quick/brief tutorial on how you determined the values for albedo/spec, etc. Because from my understanding, it's very different from traditional/old-school texturing wherein the values had a…
Yeah this is an ace little resource you have put together, thanks for giving all the sources for what you are saying as well, further reading is always fun. The discussion in here has been really interesting to read through on how oxidization actually occurs/effects metals too, something I didn't have a great handle on…
Thanks for that stevston89! Directions are fairly clear and informative. I've been reading up and found that a number of people figure out their materials prior to baking as well. I think for me, it's more of just getting used to translating between linear and sRGB...which will be a little tricky for me as I've not done it…
I just released the files for the stylized dagger I made using PBR specular/reflectance workflow. Feel free to use it if you would like. Also I am no expert on this stuff so if any of you guys notice any major issues please let me know. Here is a link to my thread where you can download everything.…
You're talking about perceptual luminance right? eg what you think it looks like visually, to your eyes? I actually think UE4 has done a really solid job of maintaining perceptual luminance all the way through the metalness range, I've definitely seen much more jarring mismatches in other PBR renderers. (e/ yes, I know…
I feel i got the workflow for pbr down pretty good, but still curious about the microSurface map and using linear space color? When authoring this map should i turn off the sRGB color profile in photoshop? Or do i need to apply levels? Like if i see a value for microsurface like #2d2d2d will that value be differnt in the…
Suggesting a company, or group, could accurately create an archetype or ideal for what every material should be is equally as laughable. All I'm suggesting, as Shrike originally suggested, is that people learn why materials behave the way they do instead of relying on a cookie cutter system to drag and drop materials onto…
updated the doc some more. Added a change log to the OP. Will be making a more indepth and detail-oriented table of contents soon. But at the moment this is the hierarchy. Blue HeadingsOrange Headings Red Headings Black Headings Also want to do a shoutout to d1ver while I'm at it. He's developed a pretty nifty tool!!…
Se we agree here; it's approximating. The part where I think you're off, is by assuming such an "approximated/hacky" material is mostly full, pure metal. A full white metallic should only be used for the pure metals. If something looks pretty close to it, use a halfway value. Using a full metallic value and then putting…
