So I am playing with the procedural ceramic tile and running into a bit of a WTF moment. On the one hand, I can dig down into the texture editor, and I get a dialog that seems to say I should be able to create tile and grout procedurally, including grout color and thickness. But that value of .5 (in a range from 0-100 according to the tool tip) doesn't seem to help much, as I don't have any units to work with. Obviously not inches, as that grout ain't 1/2". So I go to the wiki and search for Grout Appearance, and all I get is a page that says "Tip To specify a grout color, use an image file that shows both the color and the grout color." Really, cause I am looking at a dialog that seems to offer a way to do the grout color with no image at all, if I can get the size right. Oh, it also says something about Stain as a finish. For Ceramic Tile? Really? And grout gap width as a search in the wiki returns nothing. Note, no quotes, just the three key words. It's like web searching circa 1995. Gah!
So, anyone have any experience this deep in render materials? Is there some rhyme or reason to the values for grout gap width? And is this even a reasonable way to proceed, or do you end up with materials that look so bad you are better off in Photoshop making images for every tile and grout combination you ever need?
Oh, and any thoughts on that Roughness slider. I was not expecting something called Roughness to actually produce an effect that is better described as Squiggle. Nor can I think of any time that effect would be even remotely representative of reality with regards to ceramic tile.
