Blender 2.82a Mac OS with Pro Render 2.3 and eGPU
Have you had any luck improving the quality in other scenes? I'm using a 2018 13" Macbook Pro with an AMD Radeon rx 580 in a Sonnet egfx Breakaway Box 550w and the overall quality is subpar with my renders. I tried the Pabellon Barcelona benchmark and the difference in time and quality was very stark. It would be cool if I could use the same nodes I use with cycles when I'm using ProRender because I don't always have my eGPU on me. I don't know if that's possible because I'm still a noob with this stuff hahahaha.
ProRender time: 01:31.42
Cycles times: 26:19.21
No, the other benchmark scenes are not built for easy conversion to different renderers.
Sounds like you want the upcoming public release of Octane X renderer.
OTOY says the public release will add both RX 580 and Intel integrated graphic chip compatibility running under Mac OS Big Sur.
Woooow, I'll look into that a bit more. Thanks! 😀
Would you say that you have any preference for Cycles or ProRender rn? Just curious
Cycles is too slow on Mac OS, as you know, since it’s been limited to CPU-rendering only.
Prorender is useful for modeling ideas quickly.
But Octane X makes Cycles and Prorender moot. It’s fast, and has better materials.
Eventually OTOY will offer a free Octane X plugin for Mac Blender, as they do now for Windows Blender.
That’s coming, along with Octane X support for Apple Silicon GPUs, basically any recent AMD graphic card, and Intel integrated graphics, all running under Big Sur.
So Octane X is the future on Mac OS.
Today though - Octane X is still in crash-ware Beta form. For any presentation quality renders, I continue to rely on Arnold in Maya.
CPU rendering is slooooow. But Arnold has good materials, and doesn’t crash every 10 minutes, LOL.
Using Blender 2.8(most recent) and Blender 2.9 with the most recent Prorender, I get a full app crash about 30sec to 1 minute into using the rendered viewport. I bought this setup 45% for that work (55% for games! :). I don't know what's causing it for me - it seems to be working for many other people. I don't have any other extra add-ons installed beside Prorender.
I tried the latest 2.5 beta as well, and it instantly crashes on the internal 5500m.
I'm really at a loss here and discouraged after trying to get it working yesterday.
Which Powercolor 5700 XT model do you have? Red Devil and Red Dragon models are overclocked and prone to crashing, based on member reports.
You didn’t mention if you downloaded and are using the Prorender material library to build your scenes from scratch, which is the way to go. Trying to convert an existing scene built for another renderer, usually causes multiple problems.
Keep in mind that the public release of Octane X renderer and the next generation AMD cards are the tools you really want to be working with in a few months. So, if you step back and take a look at the big picture, there’s not really a compelling reason to commit to the 5700 XT or learning Prorender at the moment.
Blender 2.9 and ProPrender 2.5.7 seem to have fixed it for me.
Any other combination of Blender 2.8.x and Prorender 2.4.x or 2.5.x cause crashes within a few seconds or minutes. So far I've completed one tutorial video with it.
I did return the Red Devil but the Nitro+ has the same issues. I think it's a bug in ProRender with this eGPU combination, but who knows!
