Random "work in progress" shots

category: general [glöplog]
visy: background noise looks good with polished surface.
propeller: nice screenshot.

^^ recent shaderitis. First three are basically one fx, going through different stages. The
mario thing is based on the NES sprite and is rendered in the most convoluted way possible, because I wanted to have a lego-like dissolve effect in there, that I ended up not doing.

(imgur is scaling these images way up, sorry for that)

still a lot of things to to...

Working hard to get super basic parametrized BRDF materials working.
Visualizing 3 parameters at once: down = more metallic, right = roughness, left = glosiness.
As you can see equation sucks so far, reflected light is too strong, fresnel half-baked, etc..., but hey, work in progress!

Why do you have both roughness and glossiness?
added on the 2016-08-31 14:15:19 by Zavie Zavie
Zavie: good point, thx, I actually use wrong terms. One supposed to be Fresnel factor, which is already calculated relative to air IOR so normalized from 0..1 (not sure if it's a common practice, or better to specify IOR directly?) and the other one is roughness = 1-glossiness.

That is my goal with additional plastic/metallic parameter.
added on the 2016-08-31 14:32:40 by tomkh tomkh
Ok,but you are actually right,I actually may not need 3rd parameter (i.e. plastic/metal is already included in IOR) - still trying to figure out this stuff;P

tomkh: are you using any physically correct fresnel there? The reflections seem quite uniform. Also your speculars seem kinda bad, see for an example: http://www.neilblevins.com/cg_education/ggx/ggx.htm.

Another good basic resource to help build materials: https://www.marmoset.co/toolbag/learn/pbr-theory

Thanks noby,I knew the second link,but obviously need to go back to a drawing board now:)

Good luck with the endeavour :), especially remember: "everything has fresnel" (remember the second link's footnotes).

Some WIP screenshots of quatro for your entertainment :D

1st rough version I made a long time ago to get the idea working (in 239b :D )

some fancy concept art with some informations in german while searching a direction
( 80 days of blender? what? 2 min of paint \:D/ )

hellmood then re-wrote the whole thing (195b):

an earlier 256b version with nice colors:

the finished prod:

@tomkh: the fresnel component and how metallic a material is, are not independent values either. Metals have no diffuse and their color is due to their IoR.
The metalness doesn't actually refer to anything physical, but is handy hence the metal/roughness model (as opposed to specular/roughness).

@ferris At some point I will make it look less ugly :) Focus is to have stuff working before it looks nice but I can assure you that I think about it all the time so I will need to do it in a not to distant future :)

@sensenstahl: i like the 1st rough version more than the finished prod.
it would be perfect if there were overflow between the effects:)

@emoon: a new assembler? Want!

nope, it's a debugger (ProDBG).
