Daniel Santana (dgsantana) added a comment to T75549: Remesh takes all memory when playing around with voxel size.

But this happens with high values, not with low values, since I know about that relation. In one of the tests on windows, it took 80Gb+ and not recovering until I just killed blender. I have some experience with VDB since I use them alot on Houdini, so I didn't expect for the values I used to have this behavior.

Hi @Brendon Murphy (meta-androcto), I can confirm that indeed the relative path is on, by default. Since I couldn't figure a way to force it to be off. I added a bpy.path.abspath to fix this. Updated revision, and attached the __init__.py for easy testing.

Daniel Santana (dgsantana) added a comment to D3203: Baking system overhaul: Move baking settings from render settings into BakePasses.

Just to add to the discussion. We needed in our last project to bake the buildings of an archviz masterplan to take them to Unity for an app we were developing. And what did save us from the current clunky workflow (which is still better then the default 3dsmax baking system we used to use), was the Bake Wrangler (https://blenderartists.org/t/bake-wrangler-node-based-baking-tool-set-ver-b0-9-4-curvycavity/). The node-based approach and the ability to mix the results from different passes to create a single texture for specular/roughness/ao for example was great. But I do agree with @Brecht Van Lommel (brecht), the ability to see the results/apply them in blender would be great since we always check the results in blender and export the objects with a semi-working material.

Yup, my bad, sorry for notifying everyone. Fix the typo, it was missing the not.
As for the "custom" folder, it doesn't save to that folder, if you look at the code, it just loads any blend file as a library from that folder, but any new library is still saved to the matlib_path (line 951).

Just a side note, I had to run a few dozen of times to be able to catch the exceptio, so it's a bit hit and miss.
The other ocean_compute_displacement_x, and ocean_compute_displacement_z are in a for loop and don't seem to be writing to any of the osd->o fields, only reading. The problem seems to be inside fftw.

I agree on the calls, simply creating the modifier, generate multiple calls to the simulate. After removing them I haven't noticed any problem, but of course is better to check.
This, is a hit and miss, case, you are right this is hidding some other problem, since I can't always get a crash.

Daniel Santana (dgsantana) added a comment to D6121: Fix for ocean thread pool crash T71040.

What I noticed while debugging that sometimes fftw threads were still working when the call to release the bli_task was called, creating a sharing violation. On Windows, it *was* easily reproduced by setting a high value on the ocean resolution, but on the lastest master I can no longer reproduce the error :). So the problem probably got hidden by a recent change.
Regarding the mutex outside the local variable definition, well that as what I understood from reading FFTW documentation, but maybe I miss interpreted.

Daniel Santana (dgsantana) added a comment to D6121: Fix for ocean thread pool crash T71040.

Ok I did some digging and the problem is the threading in fftw and blender. Basically the fftw plans should be protected by a lock/mutex, and before the patch they aren't, they are outside the mutex (they live in Ocean struct. So this fix is indeed the correct way to make both multi-threading work.

Oct 28 2019, 11:47 AM
Daniel Santana (dgsantana) added a comment to T71040: Ocean modifier crashes blender..

Yup it seems. And it may be true that the problem is a conflict between the blender tasks/threads and the internal fftw threads, in which they don't wait on each other. I'm diving a little deeper. But the patch we are discussing should at least solve the threading problem, and avoid the crash. But the Ocean modifier needs more work, because it gets "resimulated" in situations where this shouldn't happen, like moving the object that as no animation.

There are never stupid questions. And yes you are correct, there isn't any installer, just unzip to any folder (I keep a folder with various blender versions, each one in its folder of course).
It will ask you when opening if you want to import the 2.80 settings into 2.82. I normally start by not importing and rebuild my settings, just in case something broke along the way.

ZBrush is more CPU bound, their viewport engine doesn't require some beefy card. I asked that because on another workstation I have which has a Radeon Pro card, it has hiccups but it's due to bad drivers which cause the GPU to overheat and then it starts to throttle, causing frame drops, on 3dsmax, Maya, sometimes in Blender.
I tested 2.80 on Radeon Pro (FullHD), Geforce GTX 2080 Super (4k, FullHD), Geforce GTX 1070 (4k, , FullHD), Geforce GTX 1060 (dual 4k), Geforce GTX 870M (FullHD), and didn't see hiccups on the viewport, this in both Windows 10 Pro, and Ubuntu 18.04.

It can also happen calling ocean_compute_displacement_x and probably ocean_compute_displacement_z.

Can confirm. Crash on freeing task for ocean_compute_displacement_y. Only happens if you enter directly a high resolution. If increase incremental to 32, the error doesn't occur. Also after that, you can enter any value without crashing.

I don't the fully know blender internals, but wouldn't an index -1 correspond to not found? Shouldn't this be handled, and just abort snapping?
From my experience with BVH trees and Octree, precision does indeed make a lot of difference.

Sorry, but finally got the crash again. This was after leaving edit mode. Focus select, enter edit mode, select vertice, focus zoom, and 'g' to start moving. Attaching screenshot with the vertex that cause the crash and the file (its the same but with more edits).
Crash was again in line 2120 of math_geom.c in the isect_ray_seg_v3.

Sorry to make lose time, but definitely is some addon, just can't figure which one, even when disabling all, the behaviour persists. But I will keep investigating, please close this bug report.

Sorry for the delay, I'm rebuilding again before your commit, and will test with defaults. The only addon that I have for the nodes is the node wrangler.

Running master 93e8c962fcc1f9979d4dbb539d5ff4e1f5295068.
So far no crashes (3h session), I do have an issue with objects with multiple materials, where some of them don't show in Material and Texture shading mode. They do appear in Object shading mode. I can restore the visualization of the materials if I allow blender to compile with USE_MULTI_DRAW_INDIRECT 1, but node links disappear sometimes (as reported on other ticket related to this)
