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.

john peterson (bliblubli) added a comment to T51608: Bug when the grid is scaled to zero.

It is just how blender works, not a bug. I also find it not really understandable that a display option has an impact on geometry without any warning nor infos in the tooltip. But it's a design task more than a bug. Zero could also completely disable that behavior like in many other cases in Blender (letting objects use the unit system as one would expect)?

@Brecht Van Lommel (brecht) and @Sergey Sharybin (sergey) wouldn't it be better and possible to take last valid texel value instead of 0,0,0 for replacing NaNs while cycling through all the texels of the texture?

I'm speaking about addons that don't support to be reloaded. The new template system allows to have different addons activated depending on the startup file chosen. It sometime lead to reloading addons (like F8) and crashes when those don't correctly reload.

your attached file doesn't crash using buildbot from yesterday in my case (tested 20 times, changing layouts, viewport mode, then F12, etc... windows 7, VS2015 build). But I have the exact same problem on a regular basis. As you say, it only happen on complex scenes and is random. So I never managed to give a simple working example.
Are you sure that the attached file really crash on older buildbots? It may be that this version is still too simple to happen often.

john peterson (bliblubli) added a comment to T50238: Cycles: difference in texture position between OpenGL and Cycles render (CPU and OpenCL).

Ok, another precision. Python doesn't suffer from this problem. So replacing the divide node at 0.0084667 with a multiply node at 1/0.0084667 workaround the bug. But it's really cumbersome. This view is at 39 unit from origin. I wouldn't call that far away, so precision shouldn't be an issue. Maybe constant folding could do this job and change the divide node to a multiply node? Or just rearrange computation to maximize precision?

@Sergey Sharybin (sergey) thanks for the update, I will test and report. The slowdown is with latest driver, but with CPU device. GPU is fast as usual. But when working on laptop, it's great to be able to compile the kernel for CPU. With master, it won't compile. With this patch it compiles. Only problem is that OpenCL CPU is (hopefully was) approximatively 400x slower than normal CPU render. It may be a driver bug, but Luxcore works great on OpenCL CPU on the same machine with same driver.

Surely there is user-benefitial progress in the split kernel branch. I've briefly summarized the current status in the mailing list.

Would suggest moving rest of non-review related discussion to IRC or ML..

Mar 6 2017, 3:39 PM
john peterson (bliblubli) added a comment to D2546: Full atomic selective SVM Node compilation (30 to 50% speedup on BMW, Barcelona and Classroom).

Thing to keep in mind is: people are using Cycles for a big production scenes, with lots of materials and different nodes, so even full selective compilation will not be giving such a huge performance improvement.

Improvement of 30% to 50% given above are on production scene from the official benchmark pack (BMW, Classroom, Barcelona)

But if you do full selective compilation you are pushing artists ti a situation when adding complexity to their scenes and materials has non-linear dependency on rendering time: one adds one extra node and render time goes up by a factor of 2.

That will not happen. The heaviest node I had during my test (I tested every single node to see impact on rendering time to make my first 3 patches) gave a slowdown of 10%. But even then it's not a slowdown compared to master, it's a lesser improvement. Going from 30% faster to 20% faster is already a gain. And if a user doesn't want the 30% speedup because it could become "only 20%", then he just leave the option unckeck?

Mar 6 2017, 11:52 AM
john peterson (bliblubli) added a comment to D2546: Full atomic selective SVM Node compilation (30 to 50% speedup on BMW, Barcelona and Classroom).
  • Regarding kernel compilation time, Barcelona takes 15seconds on my machine instead of 45seconds on master. With multi-threaded kernel compilation, it would go beneath 5sec on an 8 thread machine as the longest kernel take less than 5seconds to compile.
  • People working on materials do it in viewport, which is not concerned by this patch. So there will be no more compilation for them. For all other cases like sculptors, animators, modelers, people doing archviz, etc. most of the time they will only use library materials, thus not needing any recompile. And even people creating materials, will most of the time only use the same nodes over and over again, only the combination being changed, again, this will not trigger any recompile either.
  • For the scary case their would be a recompile: 50% faster render is so huge, I get better complete render time with this patch, including kernel compilation than on master only taking pure render time. So there is simply no reason to not use it in real production scenes.

  • I think it's definitely a good idea to ignore faces for object in bounding box mode. Those are most of the time complex meshes which are instanced a lot like trees. They would occlude the geometry the user really see and give unexpected result for the user (particularly when the bounding box is not visible in the current view, because the zoom level is too high). But for wireframe, I don't see a clear reason to do it. Maybe it could be an option in the snapping part of the 3DView header.

Using the latest version in the branch ( 681089237e33d2fe4b1c46e4a8368c686e60be34 ) I get the following results on 1rx 480 on windows 7 with driver 17.2.1 (pure render times):

john peterson (bliblubli) added a comment to T50473: inset and extrude sometime broken.

This object with this mesh "happened" during work, without script. Sadly, I just noticed the weird behavior to late. The last steps I could remember I did, didn't permit to recreate the bug.
Applying the scale indeed resolves the problem.
But still, why does the extrude properly work on 2.74 and not in master?
Well, I guess it's not a that problematic if this bug stays in master, it seems to only happen very rarely anyway. and 2.74 allowing to extrude an object in a direction that is scaled to 0 is non-sens anyway.
As the steps to lead to that mesh are nearly impossible to find, we can just let it archived until someone get the same problem.

I managed to recreate files that crash on render start with --factory-startup with dummy meshes and textures. But like @matali23 (matali23), when I reopen the file and hit render, it works. So submitting the file wouldn't help much. But it's a real problem, so it's sad if it get's ignored.

john peterson (bliblubli) updated subscribers of T50461: Some modifiers make render crashes right away on complex files.

@Joey Ferwerda (TheOnlyJoey) I report bugs since 3 years and a half now. I must say this bug is really nasty. I already tried to reproduce it by replacing every mesh with a subdivided cube with similar polycount and every texture with a generated one of same resolution. But even without changing polycount, object count and texture count and sizes, the file just wouldn't crash anymore.
As I said in my comment, most of the time, only reopening the same file, without changing anything is enough to workaround the bug. So I don't see how a file could be submitted here. Maybe let @Bastien Montagne (mont29) and @Sergey Sharybin (sergey) decide if the crash log is enough to find the bug?
