In the video I first run the denoiser, then after it finishes I switch to the DENOISED pass.Odilkhan Yakubov wrote: ↑Wed May 23, 2018 9:39 pm But, there is hasnt black blank in the video. Why?

Re: LuxCoreRender v2.1alpha0 released
Finally, ive got the test render, but it was blured image
I changed nothing in the scene. The scene is simple a cornellbox. What is wrong?

Re: LuxCoreRender v2.1alpha0 released
If the image is blurred, it means you don't have enough samples rendered.
Depending on the scene, you will need more or less samples, but it is usually in the 100-1000 range.
You can also try to change the settings according to Dade's description in the first post of this thread.

Re: LuxCoreRender v2.1alpha0 released
Hi, I'm somewhat new to luxcore. I'm experimenting with this beautiful renderer since 2.1 has denoiser and nice blender integration.
I've had some issues with 2.1 opencl rendering when I try to render resolutions above 3K on 6GB gpu + I7 cpu. Error displayed was telling me something about framebuffer is too big for gpu. Now for internet purposes up to 3K seems good enough but my client work is rarely below 5K and more often around 8K. I could render with cpu ok.
Now I understand that this is alpha but wonder if there is, or will be a workaround to the problem so that a 8K+ framebuffer fits into gpu?
Another question I have, are there some plans for out of core for luxcorerender? Having huge scene data and textures that don't fit in gpu/system memory?
Thanks for the work you do on this impressive render engine.

Re: LuxCoreRender v2.1alpha0 released
Some GPU has a limit on the largest single block of memory it can allocate (to store the frame buffer and other stuff). For instance, the old AMD HD5870 has a limit of only 256MB even if the total amount of GPU memory available was larger. Your GPU may have the same kind of limit, what GPU do you have ?lacilaci wrote: ↑Sun May 27, 2018 11:06 am I've had some issues with 2.1 opencl rendering when I try to render resolutions above 3K on 6GB gpu + I7 cpu.

Anyway, the solution of your problem is to use TILEPATH: it will store only small tiles on the GPU so the total frame buffer size doesn't matter.

I also have some questions on this topic (however only concerning CPU, not OpenCL), see my issue here:

Hi I have GTX 1060 6GB. Do you think that using a 1080 or similar would solve the issue?Dade wrote: ↑Sun May 27, 2018 11:21 amSome GPU has a limit on the largest single block of memory it can allocate (to store the frame buffer and other stuff).

is there some limitations to using tiles for rendering? Performance issues or other? And can it be used cpu+gpu?
Thanks
Re: LuxCoreRender v2.1alpha0 released
I have a GTX 980, if you give me the exact resolution, I can do a test.
TILEPATH is a bit less efficient in term of performance (there are a lot of CPU <=> GPU comunications going on) but there aren't any other limitation I can think too.

Have you tried the same test with LuxCoreUI or LuxConsole ?B.Y.O.B. wrote: ↑Sun May 27, 2018 11:44 am I also have some questions on this topic (however only concerning CPU, not OpenCL), see my issue here:
