Re: Albedo Creation Confusion
Metalness is just a constraint on specular values because artists got easily confused in the beginning. It's honestly totally unnecessary now, IMO. Internally (in a shader) it's another way of doing specular. There is no such thing as a colored metalness map. That's the whole point. It replaces specular with whatever is in… -
Re: Albedo Creation Confusion
Well this is an old technique that you'd probably want to take a second look at and update. The biggest problem is that it only works from 3 directions, so to make this really useful it'd be smart to find a method of getting more arbitrary directions. Then you'd want to take it into a PBR implementation, which has a lot… -
Re: Albedo Creation Confusion
@leleuxart I've just released it! Wanted to bump this thread too since yall inspired me to release the node, and I gave the thread a good mention at the end of the video :) https://www.youtube.com/watch?v=kUCDIAupRmQ You can grab the link from the video description or from my own thread. Thanks all! -
Re: Albedo Creation Confusion
Ah okay, so it's primarily from the scattering. I wasn't thinking of that. For fabrics, car paint, etc. I always expect a special shader with the appropriate effects(with their own rules for the textures), but didn't consider SSS for some plastics. SOMEDOGGY, that Substance node is going to be a lifesaver. I look forward… -
Re: Albedo Creation Confusion
Yeah Teddy told me the data in that chart is probably wrong, but not massively so. It's still valid as a means to compare where various materials fall on the spectrum. As I wrote in the tutorial that that image comes from, creating art content isn't a paint by numbers process where you just look up numbers on a chart, but… -
Re: Albedo Creation Confusion
You know, I'm going to dig around and see what I can't come up with. I live near SDSM&T, which kinda has enough focus on metallurgy to put "Mines" in their name. I don't know that I'll find what you're talking about exactly since it isn't an ID school, but I should get pointed in the direction of material study like that. -
Re: Albedo Creation Confusion
I would really be interested in this too. @somedoggy Those developments sound interesting. When you are talking about sggx you don't mean an approximation like in this paper: http://blog.selfshadow.com/publications/s2015-shading-course/activision/s2015_pbs_approx_models_slides.pdf I guess this is something different? And… -
Re: Albedo Creation Confusion
Indeed so! Charts are great reference material, but what's better in some cases is eyeballing it. A physically accurate value may not look as good as a fudged number that you eyeballed to match a reference image. I'd imagine a lot of factors come into play, most notably the fact that no two dirts are identical, no two… -
Re: Albedo Creation Confusion
Thanks :) I've been writing PBR shaders for a couple years now, found I enjoy it just as much as the art itself. What in particular are you looking for? If it's the above, I'll be putting the Substance node up this week once I do some cleanup (but it's not tied to any physical scale so it still requires good art… -
Re: Albedo Creation Confusion
If you use PBR properly your model won't look dull, including a flat base color. If it does look dull, it is most likely a problem elsewhere, such as lighting, bad material values, lack of proper textures, etc. If you put no lighting into your base color then you want to make sure you are using an Ambient Occlusion map in…
