Hello AMD, I am picking blender back up after a few years away from it and am trying to work exclusively with blender 2.80 with eGPU running on Mac with Radeon Pro WX 7100. Since rendering options are limited, I decided to participate in random bug reporting while the ProRender add-on for Blender 2.80 is in development/testing. Not sure how often I'll have opportunities to post but hope this is helpful.
I will likely continued testing with the same blend file until a version of PR passes all my render tests and then movie onto a new file for testing. Note, I will have CPU rendering off and only attempt GPU rendering with all tests. With this first test, viewport rendering works, image rendering fails. Details below and attached. Hope this is helpful!
OS: OSX 10.14.3
Software: Blender 2.80 (2.80 2019-02-08, Blender Foundation)
ProRender version: 2.0.1
Test Blender File:
EGPU Chassis: Razer Core X
eGPU: AMD Radeon Pro WX 7100 (Metal)
AMD PR RESULTS:
Viewport - render worked
Render Image - crashes blender within ~1-2 seconds
