Yegor (Yegor) added a comment to T56497: (Dyntopo) Snake hook sculpt brush slips off and affects the part of the mesh behind.

Is this the issue with the Snake Hook slipping instead of holding onto the mesh?
B 2.79 - Snake hook works as expected.

B 2.8 Release - Snake Hook slips and doesn't hold on anymore.

blender-2.81.0-git.10001d909905-windows64 - Snake Hook still has the issue

By the way, not only that. A couple of subdivisions can lag a lot while mesh editing. 2.79 doesn;t suffer from that. A lot of people complain about subdiv performance on editing.

It's not just a change in tessellation, changing vertex position and face areas can lead to a different child particle distribution even if the tessellation is the same.

Yegor (Yegor) added a comment to D4304: Compositor: Added denoising node.

I think we can merge this into master quickly, I don't really have any issues with the implementation as it is.
It can be committed disabled by default, and then we can commit precompiled libraries, set up the buildbot and enable it by default soon after.
I would like to unify this with our existing denoiser (or other future denoisers) at some point, preferably before the 2.81. The current Cycles denoiser could be made to work at the end of rendering, on the entire image buffer. This would take some extra CPU memory, but it requires fewer passed than it used to and we are loading those into memory at the end anyway.
Then OpenImageDenoise could then be integrated outside the compositor as well, and the Cycles denoiser could become available in the compositor.

Tested some more scenes and i guess it's scene related and can vary a bit. The speed is about the same. Somehow the tile size speedup slipped away from me. The light behaves a little different, though, but the task can be closed now, i think.

Yegor (Yegor) added a comment to T55351: Sss gpu render speed degradation.

No no, the tile size is understood and i'm really happy with those news. On my hardware it works best on 32x32, but the thing is even with this sweet spot it's still a bit slower than 2.79b with 256x256 GPU only. I could get the exact same time with the hybrid render - 1:12, but it's still more, than gpu alone on 2.79b, right?

No, i used GPU only render with 256x256 tile size.
And by the way, i didn't know about smaller tiles improvement! Now i've tried 32x32 and got 1:18. But it takes still a bit more than 256x256 on 2.79b (1:12)

Yegor (Yegor) added a comment to T52615: Glass BSDF has colored reflection, what is wrong..

Thanks to Brecht, there is a quite obvious solution. Use Glass BSDF and plug volume absorption shader in the volume input. We get correct reflection + correct colored absorption in the glass!
And yes, i mentioned that we can use Principled BSDF for colored glass, but it's a bit slower and doesn't provide physically absorption all alone.

Yegor (Yegor) added a comment to T52615: Glass BSDF has colored reflection, what is wrong..

I think you got me wrong. Glass is a dielectric and all dielectrics have reflection not colored. If a shader called Glass, it should behave like glass. Of course, glass can have a colored reflection if it's not a usual silicon glass, but have some metals mixed in it. There's is nothing to do with volume absorption.
The default glass shader should have the white reflection and colored refraction. If we'd like to have a colored reflection, then we mix refraction node with glossy node and so on.

Sybren, i have tested it with 2.78c official and since there was another bug in that release i reported, it's unable to export whole animation of the abc file with vertex colors checked. Blender exports only two frames of animation in that case. But even then those two frames have no vertex color animation. That two frames export bug is now solved in the trunk.
Anyway, it's not a regression. It's a lack of feature, i believe.

By the way. It's not alembic export related perhaps, but the dynamic paint system itself. I could not find a way to bake animated vertex colors from dynamic paint onto object. Applying dynamic paint modifier simply leaves the first frame of vertex color baked. Deleting it leaves no vertex color at all. But i think alembic exporting should read the information about vertex color from the modifier per frame.

Here're two files. _vc - is for vertex colors. You can notice they have a huge difference in sizes. And i don't think it will be helpful.

Well, this is embarrassing. I can not reproduce this behaviour anymore on a new object or in a new file. But this file still has the issue, and it's something with this exact object. If you create another one and link the same material it renders fine, but if you copy the broken one, or copy the mesh and separate it into another object it will have the issue still.
