I only updated the darwin 10.9 libraries for the 2.80 builds, and this bug report is about 2.78 with Python version 3.5.2 in the screenshot. So it should not have caused this issue.

Brecht Van Lommel (brecht) added a comment to D2677: Cycles: Improve sample weighting of the Principled BSDF specular component.

I think this is the difference to a correct fresnel, where the microstructure is considered, that every node tree based Uber shader has. The higher the roughness, the more the fresnel wrt the surface normal is off to the integration. That's why I decided to put the weighting into the shader call. I've also seen the problem with importance sampling but didn't want to implement the approximation in the first run as it was more important for me to be as close to Disneys implementation as possible.

Brecht Van Lommel (brecht) added a comment to D2679: Cycles: discard unused Principled BSDF inputs at shader compile time..

It should be fine to pass a zero tangent, we do that in other cases as well, and if that doesn't work we can fix it. Linking in the default geometry node means extra unneeded work.

Sat, May 20, 6:50 PM
Brecht Van Lommel (brecht) added a comment to D2677: Cycles: Improve sample weighting of the Principled BSDF specular component.

Also, this is using the Fresnel along the normal instead of Fresnel integrated over the microfacet normals. I guess that is a decent approximation, though I'm not sure how big the difference gets, if there is some case where it is very far off and noise is increased.

Brecht Van Lommel (brecht) added a comment to D2673: Cycles: Removing "white pixels" from a rendered image.

It may be that there is something to be fixed or improved here. The first thing I would suggest to investigate would be rendering the two MIS components separately, by replacing power_heuristic() by 0 or 1, that might reveal something. On the other hand it might just be a case where both MIS components are noisy.

Brecht Van Lommel (brecht) added a comment to D2662: Cycles: Adaptive rendering based on a norm of rendered pixels.

Adaptive sampling is certainly a feature we want to have in Cycles. I think we need a more advanced implementation than this though, with fewer users parameters, but mainly something is more robust. Looking only within a single pixel with a simple metric like this is not very reliable and will give artifacts in common cases. Maybe this is good enough, but then we'd really need to see some renders to prove that.

Brecht Van Lommel (brecht) added a comment to T51408: Cycles - Principled BSDF Shader - Transparency is not working as expected.

I think we definitely need to make the Principled BSDF complete enough that you don't need to mix in other closures, that's kind of the whole point. To make it faster for users to set up materials, and to provide a standard node for things like texture painting and material import/export. Not saying it has to be done right now or as part of this bug report, but certainly at some point.

If you replace a node in the properties editor (and in the node editor), Blender will attempt to preserve any values and links for sockets with matching names. The issue here is that the Roughness in the Principled BSDF and Diffuse BSDF have a different meaning.

There is not much we can do about such bugs on the Blender side besides waiting for NVidia to fix them.

The timeline is one of multiple editors that has time along the X axis, like the sequencer or graph editor.

Brecht Van Lommel (brecht) closed T51326: Disabled layer is still rendering as "Invalid".

I don't see a bug here, the render layer enable/disable means that it will not render as part of the regular rendering process. If you explicitly press that button to render that specific layer then it does render, but I don't see how that's a problem.
