I am using a 2019 Mac Pro 3.2GHz 16 core processor, with 192GB memory, and 2 AMD Radeon Pro Vega II 32GB graphics cards in the latest 2.9 Blender build, but when I try to render an image or animation that works in Cycles or Eevee, I get the message: ERROR | ('incorrect operation', 'SCALE') Please see logs for more details.

I am doing an animated film and working with an artist remotely who is using a PC, and he has no problems with the scene, and has shared it with others that are working on PC's, who do not have a problem either. 

Any advice on what might be causing this issue? I've wracked my brain about it and cannot for the life of me figure it out. 

Thanks,

Blender 2.9 is not support yet. Did you try with Blender 2.83.2? Can you share the scene? Did you render with just GPU select?

[davidfujung]

Yes, I've tried with Blender 2.83.2 and I have the same problem. How do I render with just GPU selected? I think that's what I have selected. I've gone into preferences, system, and under Cycles Render Devices I have NONE selected. Is that right?

[davidfujung]

Okay, under render devices, I now see where I can check CPU or either one of my 2 AMD Radeon Pro Vega II cards, or all 3. I've tried rendering with just GPU, just CPU, and both... and it still gives me the same error message. Here is a link to the scene (pls do not share). Let me know if you have any luck getting a rendered image with ProRender.

Yeap, I can confirm this bug with RPR. It seem it occur while RPR not support some Blender nodes. Should waiting for official answer.

"

/scripts/addons/rprblender/nodes/blender_nodes.py", line 1212, in export

    raise ValueError("Incorrect operation", op)

ValueError: ('Incorrect operation', 'SCALE')

"

From my experience if You wanna render with RPR you should make scene with RPR nodes. RPR always will be one ore more step behind of Blender eevee/cycles nodes in terms of supporting them.

I'm working on a project with an artist in another country who is using a PC and Nvidia, so we need to find a common ground. I just bought dual Radeon Pro Vega II's so that I could render faster. Do you think RPR will address this issue soon and have an update, and do I need to bring this to the attention of anyone else there?

Thanks for your help and input.

Thanks for uploading a scene!  It really helps.  We'll take a look at getting fixed.

Hi there.  I fixed the issue, the scale parameter on vector math node was not being handled.  You can wait for a new build or take a look at the python file, it's a simple edit:

Thanks for fixing the issue. I am not code savvy at all, so I think I'd better wait for a new build. When do you think that will be coming out?

[davidfujung]

hey there, 

do you know if there's a new build yet that fixes this issue?

thanks,
