Hello,

With 3.08.0.10 I cannot render a scene which i can render in 3.08.0.09 much problems. (first render in 3.08.0.09 fails, press f9 again and I can render what as long as I want, whatever I want)
Easy to reproduce:
Copy the 3.08.0.10 plugin, start Lightwave, load scene, press F9, fail, press F9 again, fail, etc etc
Copy the 3.08.0.09 plugin, start Lightwave, load scene, press F9, fail, press F9, it renders, F9, it renders, F9 it renders etc etc.
Copy the 3.08.0.10 plugin, see above, no succes.

An empty scene renders in 3.08.0.10,and some smaller scenes aswell.

I have attached the logfile.
Setup is 1x 1080, 2x1080 TI and 1x 780TI

Any idea?

Best regards,
Hans

Hi,

Well, you are running out of GPU memory, so you are going to need to disable the GPUs with less memory (the 780ti) to render this scene, or enable the out of core feature, to see if it helps.

Code: Select all
00:00:40 (0040.20) |  <> Mem Used/Free/Total: 2494 / 0 / 3072
00:00:40 (0040.20) |  <> Triangles/DisplaceTris/Hairs/Objects/Voxels rendered: 1541581 / 0 / 0 / 1100071 / 0
00:00:40 (0040.20) |  <> Textures RGB32/RGB64/GREY8/GREY16 used: 177 / 0 / 0 / 0
00:00:40 (0040.20) |
00:00:40 (0040.20) | ... Init rendering ...
00:00:41 (0041.56) * OCTANE API MSG: CUDA error 2 on device 2: out of memory
00:00:41 (0041.56) * OCTANE API MSG:   -> failed to allocate device array

OK thanks. I hope OTOY team will introduce it again, it was nice with previous versions of Octane...

Hmm, some how, out of core was disabled in 3.08.0.10, after enabling it, it renders. I cannot check now if 3.08.0.09 was set to, as far as I remember i did set that by default on enable for me.
Weird stuff. At least it renders now.

Hi Juanjo,

Why don't I have this issue when I'm using 3.08.0.09? I can render with that version of the plugin! (after it first complains and then it renders)

Best regards,
Hans

What are Diffuse and Specular values for in Metallic Material, they don't seem to do anything.

It is hard to say. Perhaps you are running just in the GPU RAM limits, and the .10 build needs somehow a bit more memory. Are you using a 780ti also for the display? In this case the GPU memory available could not be always the same.

Thanks,

Hi Juan,

No, the 780ti is just a card to render. Displays are connected to a 1080ti and the 1080.
When it renders, it show 0 out-of-core memory used, while it wont render when i disable out of core .
It renders now, it's weird , but I'm happy .
Thanks!

Sorry, I don't have the exact details about how these parameters work, but they can be related also to the specular map texture. The API description is:

P_DIFFUSE: Diffuse reflection channel
P_SPECULAR: Specular reflection channel which determines the metallic color. If the index of reflection is set to a value > 0, then the brightness of this color is adjusted so it matches the Fresnel equations.
P_SPECULAR_MAP: Controls the blend between the diffuse and metallic reflection.

Hope this helps,
-Juanjo

Thanks, this helped, but we don't have Specular Map in the node edit panel and this one is important to mix between diffuse/glossy appearance.
