Black Image rendering on GPU

Post by netlinker » Tue Feb 04, 2020 1:38 pm

Hi,

I have a problem with my Blender Luxcore setup (blendluxcore 2.2 blender 2.79).
Every time I try to render a scene with amd gpu support, it crashed the first time and renders a black image from there on even if I set the render to CPU only.
I have the unusual setup of a AMD FirePro V4800 and a Nvidia gtx1080.
It seems like the kernel compile for the AMD crashes and ruines some settings from which blender does not recover.
Even if i start with a blank new scene this Problem stays persistently. The only way to get rid of it is to reset Blender to default settings and scene.
When I do so, the renderer is working (cpu and nvidia) as long as I don't use the amd card for rendering or load any old file that used the amd card.

The Problem is now that I have setup a quite complex scene which is now only rendering black images.

Any ideas how to rescue the scene?

Initial crash using AMD:

Re: Black Image rendering on GPU

Post by Dade » Tue Feb 04, 2020 2:18 pm

Question: I have the feeling you are on Linux :?: And you are using some open source driver instead of AMD official driver :?: It looks like you have a broken OpenCL installation. It is not uncommon, I have to install AMD/NVIDIA drivers in a precise order and with some specific setting to have them work fine on a mixed AMD/NVIDIA multi-GPUs setup.

Does LuxMark work with your 2 GPUs ?

The Problem is now that I have setup a quite complex scene which is now only rendering black images.

Any ideas how to rescue the scene?
It is a quite strange problem, I would try to install the OpenCL-less version of BlendLuxCore so it should remove all OpenCL related problems. I would than load the problematic scene, set the render engine to CPU and save the scene (than you can install the OpenCL-enabled version again).

Re: Black Image rendering on GPU

Post by netlinker » Tue Feb 04, 2020 3:23 pm

Yes I am on Linux and the AMD driver is the old radeon open source driver.
I didn't get Luxmark to run. It's just saying this on startup, but I wasn't able to figure out the problem:

Code: Select all

terminate called after throwing an instance of 'cl::Error'
  what():  clGetDeviceIDs
./luxmark: line 12: 27538 Aborted                 (core dumped) ./luxmark.bin "$@"
Switching to blendluxcore 2.2 without opencl solves the problem. Everything is rendering again as it should.
I then saved the file and switched back to blendluxcore with opencl. I had to find out that it was still rendering just black, although rendering mode was switched to BiDir, because I assumed this would force rendering on cpu.
But at least I can now work on my model without opencl for now, which is great.
I will try this evening what happens if I switch to another architecture (new amd with amdgpu driver and nothing else).
Should I provide any additional information?
I could for example do a diff of the blender config file before and after the crash of the cl-kernel compilation, as this seems to brake something in the configuration file also and not just the current model.

Code: Select all

It still seems to use the AMD FirePro for something, although rendering with BiDir which seems strange.

Like I wrote before, your OpenCL installation is broken. Is your monitor connected to the AMD or NVIDIA GPU ? Or you have multiple monitors ?

You have to use AMD binary drivers and to be careful in driver installation order (for instance, I have to install first AMD drivers than NVIDIA head-less driver or AMD installation will break NVIDIA one).

You have first to fix your OpenCL installation (i.e. be able to run LuxMark) otherwise OpenCL-enabled BlendLuxCore is never going to work.

Yes, LuxCore uses OpenCL for 2 things:

1) rendering;
2) image pipeline (i.e rendering post-processing);

So you have, not only to set a rendering mode to PATHCPU or BIDIRCPU but also to disable OpenCL image pipeline processing (not sure if there is a setting exposed in v2.2, it may have been added later in BlendLuxCore).

Aha, this explanes it.
I'm working on getting opencl to work now for the AMD.
Setup is split. I'm using one monitor with the AMD and one with the NVIDIA. Although the NVIDIA messed up my xorg.conf which in turn disabled the AMD video output (I had the AMD first).
The possibility to switch the opencl device also for the image pipeline like its done for rendering would solve this problem, but that's probably out of scope as the reason is the non working opencl in the first place.

I have a Linux setup with AMD GPU connected to a monitor and head-less NVIDIA GPU and it was quite tricky to find a working software setup.

Usually, one vendor installation procedure breaks the other one for OpenGL/OpenCL and the Linux distribution updates try to break both with Mesa software OpenGL/OpenCL :roll:

Just to say that attaching both monitors to a GPU and using the other GPU only as compute device may be easier. Installing NVIDIA GPU as compute-only device is quite easy and without side effects.

I don't remember when it was exposed (quite a while ago), but yes, this is possible in the latest daily builds.

Thats exactly what I just did, and it fixed the issue permanently. So thank you for the tip with the defective driver. I installed the Mesa/radeon cl driver alltogether. I tried to get it working, but clpeak hard-crashed my pc (It seems there is something badly broken in that driver). As I guess the performance of a card that old is not worth the trouble, so deactivating is the best solution here.

In this case, I would say case closed, unless someone is feeling bored to death and wants to torture himself by debugging something that most probably is not worth fixing :D.

I will try out 2.3 in the near future 2.3 beta 1 didn't work for me yesterday, but I still have to investigate on that one.

Last but not least, thank you both for this awesome fast support!
