john peterson (bliblubli) added a comment to T52135: memory usage is higher after rendering with cycles.

another thing is, when I render on 2 GPUs a scene that takes more then dedicated memory, the system memory will be used. If those generated textures are kept around, we have 3 times the textures. The cache Blender silently creates and the 2 versions created by the OpenCL driver. As the time needed to initialize rendering is not much faster the second time compared to using the cache, but many GB memory are away, making it more certain that swapping will be triggered, the cache may greatly slow down render for a benefit which is pretty low, at least in my tests.

ok, then it's not a bug, but wouldn't it make sens to only have this behavior when "persistent data" is checked and free it otherwise?

john peterson (bliblubli) added a comment to D2745: Cycles: Pack kernel textures into buffers for OpenCL.

Really helpfull addition and it seems very robust. It shows that the latest AMD drivers also allows to use swap for buffers. I managed to render a scene that took 36GB on a 16GB (system) and 8GB (RX480) system. Of course, it was slow, but still interesting.
Only thing that it showed is that cycles seem to have like a memory leak or hidden cache. It doesn't come from the patch nor driver as the same scene rendered on master with CPU also takes 7GB after rendering VS 1.5GB before on windows 7 x64. It looks like if "persistent data" option was ticked and textures were cached. I made a simple scene to showcase:

john peterson (bliblubli) added a comment to T47811: Blender 2.8x / Python, Proposed Changes.

As suggested today on IRC, making robust naming conventions for bmesh operators would help new coders to jump in. It will be very helpful for making the nodal everything work faster. At the moment, the use of for example underscores is pretty random. Having easy to search names will give more time for real coding.

john peterson (bliblubli) added a comment to T51977: new depsgraph removes the grass in victor scene.

After further investigation, not only the hidden particle system is triggering problems. In old depsgraph, it the subdivision modifier is also hidden, the particle system is evaluated, but at the wrong place. Only solution is to manually make it visible in viewport and change something that triggers a new evaluation many times, until it updates (like setting the particle system on and off. In some case, it has to be done 3 or 4 time to really update the particles positions

john peterson (bliblubli) reopened T51554: OpenCL Textures exceed available single buffer allocation memory limit as "Open".

ok, I can confirm it crashes although the scene is very simple. Only planes and some textures, but nothing fancy as far as I can tell. Only 64 x 8bit textures at 4096*4096, which is 64MB per texture with RGBA, which is 4288MB of textures at max.
It looks like all textures try to be allocated at once, instead of 4GB chuncks, which is crazy and would prevent using today's GPU memory with low poly scene with a lot of textures.
@Stefan Werner (swerner) you wrote the code for infinite textures, maybe you can have a look here on how to allocate chunks of 4GB max at once.
Limiting rendering to less than 70 x 8 bit textures in 4K in 2017 is way too low. Many displacement maps today are 16 or 32bit, HDRs are also very big.
As an element of comparison, Luxcore 1.6, which is now more than a year old takes 1100MB (1400MB used of which 300MB are Blender's UI) of memory to render it.

  1. Did you update your driver to latest version
  2. OpenCL can use your system memory, so there should be no memory limit other than your GPU+ available motherboard memory

john peterson (bliblubli) updated subscribers of D2662: Cycles: Adaptive rendering based on a norm of rendered pixels.

In my tests, noise is even, which is good and overhead of analysis seem to be low. But setting a norm of 0.005 and steps of 4 gives the same result as norm of 0.01 and steps of 16. A norm of 0.01 and a step of 4 halves the time compared to same norm but step of 16, although in theory, the max difference should be of 12 samples between those 2 settings. As I rendered with max 1000 samples and a norm of 0.01 compares in quality with 200 samples, a step of 4 could stop in the strongest discrepancy case at 200 samples, while the 16 step case would stop at 212samples, which wouldn't make a 2x longer render time. Plus the higher step value should reduce the overhead of image comparison.
norm 0.01 step 16
render time: 4minutes


norm 0.01 step 4
render time: 2min 10

norm 0.005 step 4
render time: 3min54

Ideally, same norm should give about same noise level whatever the step is. Higher step may make noise distribution less even, but not really impact overall noise level.
From a user point of view, I would replace the norm by a quality slider between 0 and 100 like for JPEG and all lossy algorithm. 100 would offer a picture with an imperceptible noise level and 0 would be a 1 sample render. 99 would allow a variance of 1%, 20 would allow a variance of 80%, etc... But @Lukas Stockner (lukasstockner97) may have some good experience here on how to best map those values for the user.

At least on windows, there is no crash. I tested on latest buildbot, VS2015, on victor scene, reverted during synchronization with new depsgraph ('using new depsgraph' was printed in console, so there is no typing error on my side). Maybe it's Linux-specific or random due to some threading issues?

Ideally the adaptive sampling should take color management into account indeed, though in general it's unknown what kind of image transforms might be applied in compositing. A simple color_scene_linear_to_srgb() or sqrt() might already see a noticeable improvement.

@Bastien Montagne (mont29) If the problem solution is as simple as deleting the group when deleting the last instance, why not do it directly for the user? At least for the MB garbage it makes when making linked librairies local, wouldn't it be possible to solve the problem when the groups are made local?

john peterson (bliblubli) added a comment to T51755: Hair particle system and OpenCL issue on AMD Rx 480 and/or AMD Rx 470.

with 256x256 tiles (recommended size in the manual), using latest master and latest drivers from AMD on win7 x64, your file render in 1min46 with one RX480. So it would be 53s on 2 cards, which is faster than the time you report with 2.78c using 2 cards.
Second thing is that BPT wasn't available for the split kernel in 2.78c, so the file couldn't render.
Setting as incomplete until more informations are provided.

john peterson (bliblubli) added a comment to T51755: Hair particle system and OpenCL issue on AMD Rx 480 and/or AMD Rx 470.

@Renato Meneses (renatomeneses) it is indeed very unlikely to happen. In very intensive rendering scene, cycles uses max 85W on my RX480, while the card draws 160W (above the 150W of PCIE specs) while rendering real time benchmark scenes like furmark. Cycles heavily underuse the GPUs (on both CUDA and OpenCL) compared to real time 3D apps, especially benchmarks. So the only thing that could burn it while rendering would be if your fans are defects, but even then, the hardware should just shut your PC down to protect it.
Whatever happened, it's not the software job to monitor temperature. Also note that overclocking, changing voltage and all other modification leading to warranty void are allowed by drivers from all vendors, but are risky and thus not supported. So I would recommand you to use latest build, which is much faster for your configuration anyway, but leave all driver options at defaults.
2.78c is not supported anymore. But I'll let @Mai Lavelle (maiself) and @Sergey Sharybin (sergey) decide here.

john peterson (bliblubli) raised the priority of T51734: batch previews segfault on some materials from "Incomplete" to "Confirmed".

I also have some Blendermarket materials, so I had a look as it may have come from cycles. It comes from the cgc_oak material. But what is impressive is although I spend a lot of time to bisect, only retaining a glossy shader and the material output is enough to reproduce the crash. Of course, neither the full nor the simplified material crash on normal rendering with cycles. So I think the problem doesn't come from cycles.
Here it is, a cube with 1 shader creating a seg fault:

Kernels recompiles now, but on every change, even those that don't change anything to the used kernel. For example, max_closure is set to 64 for viewport rendering to prevent recompiling. Since this patch however, adding a shader to the nodetree triggers a recompile, although having 1 or 2 shader is not important as it will be set to 64 anyway.

john peterson (bliblubli) added a comment to T51603: Shrinkwrap modifier of target curve is ignored when using the Curve modifier.

I think it's more a design problem than a bug. It's one of the area in Blender that doesn't follow the philosophy of "don't think for the user". The depsgraph will decide in which order the modifiers should be applied and sometime fails at finding the right order, because in some case their are several possibilities, all valid and it's more a question of artistic decision.
The solution to it would be to have a way for the user to order modifier execution. The everything node system will solve it on the long term. In the meantime, it could be solved with a scene stack of modifiers instead of being limited to object stack.

I would exclude release kernel from this. Many users work on stable but try buildbots regularly. As the buildbots use the same folder as the last and not the coming release, it will make the stable release to recompile all kernels every 2 weeks.

I can also add the emission shading if this is a liked feature for the principled shader.

You can also use a mix. As Jesterking said, you can cherry-pick all commits related to one tool only. Then you only have a few commits related to several tools that can be copy-pasted by hand.

@João Araújo (genio84) Please split the diff per tool. It will be hard to get a quality review for all of them before 2.79. It will allow to commit some of them independently.
