    Pascal had posted looking for testers. Thought I would start a thread for it. I was going to post on Cycles Disney Shader but, it looked like a different project.

    Here is a test build = cycles_disney_brdf_Win7.x64-dbad91c
    Jens has a linux build as well...




    Cheers,

    i Downloaded the latest build 2.78.4 from Graphicall, but there are no disney shader in it, di I do something wrong?

    to use Disney's "Principled" ubershader use the special build available at the link in mentioned post
    or build your own blender version

    It is not in Master yet.

    I know that this shader is not in master, that is in the official BF build. as of 2.78b, but this build that I downloaded at Graphic all has the name "Blender 2.78.4 Cycles disney brdf" so I assume that you would find the shader there, if not I do not understand the point with this build. The build in the link is 2.77 and it has the disney shader as you say.

    Thanks,
    it must be my age or my ADD that make me don't see what is right in front of my eyes, maybe the eye is in the way ? would it not be better to call the build Principled.

    It's just too much of everything, thus confusion (spam and junk) blends in - making lack for taste (vision).
    Have your better self in peace and enjoy creativity - always fresh & tasty seasonal shakes

    From this thread
    with build 26e906d of cycles_disney_brdf branch rendering this file from 3dcal I think we got a bug:
    render path, then switch to branched (raise AA samples), and render again.
    In plain path you'll see color desaturation in SSS zone, while in branched there's only base color green as if it is ignoring the SSS color.
    Is it already fixed in newer builds? Should I file a bug report?

    Comparison required by 'lsscpp' in another thread, about SSS in PT vs BPT. Using latest Blender from cycles_disney_brdf branch compiled today.

    I am not sure if I have used a similar samples configuration in BPT and PT, so I can not be sure if this can influence the SSS result. BPT using all samples fields = 1 and AA render samples = 1000. PT using render samples = 1000. BPT took about 15 min to render and PT about 6 min:

    Used blend file from here (modified to can work with latest principled BSDF)

    @lsscpp, On IRC people recommended commenting on the problem in Cycles Disney BRDF differential entry instead of opening a bug report:
    https://developer.blender.org/D2313

    Do you have an account and could you comment on the problem there?

    @lsscpp, reading your comment in the patch entry, now I understand what you were referring to. Yes, with BPT does not take into account the SSS color.

    Yeah, this looks like a bug. I'll have a look into this the next days and will come back to you with feedback on it as soon as I found out what's wrong.

    Thank you Pascal!
    Do you think Principled BSDF could be officially included in Blender 2.79?

    Does it add much overhead to expose some of the internal results to output sockets? Like diffuse and both specular color contributions, fresnel output and so on. Or does this just sound like a really strange request?

    Would love these outputs, I always design my custom node groups that way.
