Just a tech-minded artist looking to use blender for webcomic production. I have some talent in the art of breaking this under controlled conditions (and sometimes, not so controlled).

Zauber Paracelsus (zauberexonar) added a comment to T49190: Model scaling distorts hair that uses kink.

I found a simple workaround for this issue: hooking up drivers to the kink's Amplitude and Frequency properties, and in the driver multiply their desired values by the model's scale.

Zauber Paracelsus (zauberexonar) added a comment to T48115: Rendered Viewport Crashes Entire Computer.

@Sergey Sharybin (sergey) Thanks for the tip. Though, nothing showed up on the memory test. Just a bit ago though, while booting up to my Windows drive, my motherboard's utility software gave me a warning that one of my chassis fans (one on top of the case, directly above the CPU) was not running. I fiddled with the connections and fixed that. The problem doesn't seem to happen anymore.

Please close this report. I've encountered this issue outside of blender (youtube html5), so I think I can reasonably conclude that my computer is developing hardware problems.

I booted up with my Windows 8 drive, and my computer still locked up after fiddling around in rendered viewport. So, the issue is not specific to Linux/Ubuntu.

Zauber Paracelsus (zauberexonar) added a comment to T47234: Excessive BVH build time for dupligroup instances of hair-covered objects.

I think I'll just turn spatial splits off then. A quick test render on an urban scene I've been working on showed a 20-30 second reduction in render time with spatial splits disabled, and a small reduction in memory usage.

Zauber Paracelsus (zauberexonar) added a comment to T47234: Excessive BVH build time for dupligroup instances of hair-covered objects.

As a note, I was able to partially alleviate the problem by dividing the hair-covered mesh into quarters, and then splitting each quarter off into a separate group. This brought the BVH build time for instances down closer to what it was for the originals.

Zauber Paracelsus (zauberexonar) added a comment to D808: Adaptive stopping and sample distribution for Cycles.

@Mircea Kitsune (mirceakitsune): Read back a few posts. This branch has been abandoned by Lukas Stockner due to some problems with the implementation, and he said that he would be looking at some alternatives for reducing rendering times.

Zauber Paracelsus (zauberexonar) added a comment to D808: Adaptive stopping and sample distribution for Cycles.

@Peter Boos (PGTART): It will compile under the 2.76 release. I have not tried compiling it under the 2.76a or 2.76b release. Getting it to compile under the current blender would require you to delve into C++ coding, rather than git. I may take a stab at updating the patch myself in a day or two, though I don't know how successful I would be at it since my skill with C++ is lacking.

This change may actually cause problems for me. I had observed an issue on the Refraction BSDF where a few tiles on the refractive surface would take a few orders of magnitude longer to render when their facing was almost perpendicular to the camera, and they would often take much longer to render than the rest of the image.

Zauber Paracelsus (zauberexonar) added a comment to D808: Adaptive stopping and sample distribution for Cycles.

New version, now rebased to the current master. No changes in functionality.
There was quite a long silence around this patch, so here's an update and the way I see it:
This approach kind of works, but not nearly as good as it should. It's not robust at all,
sometimes it just gets stuck on single pixels, sometimes the result is quite blotchy, sometimes
tile borders are extremely visible.
I'm looking into many different approaches currently and it looks like there is a lot of protential.
Cycles' design makes some of them impossible, but still, a big improvement should be possible.
Parts of this patch will be reusable, but the approach of just taking the variance is too unstable.
So, status of this patch is: It kind of works, but I don't consider this to be viable for master anymore.

Further info: the fur in the example file I gave was not actually using the material with the texture. Setting the correct material to the hair system still reproduces the issue, and further testing reveals that simply having a textured material present in the object's materials will reproduce the issue, whether or not that material is used.

I apologize for being late replying to this. Re-running install_deps.sh does fix the collada issue. However, the resulting binary was crashing when rendering most scenes (and I mean it crashed immediately the moment the render begins, and nothing appears).

For the nightly, the hash is 6e97db7. For the build I compiled myself (where the issue still repros partially), there is no hash. This is the output from git on the command line:

Issue repros on my build from just a couple hours ago that was compiled fresh off of git. However, the issue does not repro at all on the nightly I just downloaded.

@Bastien Montagne (mont29): I just freshly compiled blender from git this morning. The crash no longer occurs with the original model(s) I discovered it on. However, it continues to occur with a slight variation on the repro steps I posted above:

Further testing, and with new repro steps. It'll occur on ANYTHING you use Transfer Weights on.

Actually, I should point out that the problem begins with using the Transfer Weights function in weight painting mode.

Okay, I've made another repro file. This one does not produce the crash, but rather sets the stage for the trigger conditions. For this I have used a different model off of blendswap, since I do not yet intend for the character models to be available in public.

I don't think the problem is so much the file, but rather it may be some kind of mishandling with weight painting or deformation? The crash occurs after I transferred weights from one model to the problem model. But when I instead just created the DEF-head group and then set it to 100% on all vertices, there were no problems.
