Hey friends! I'm trying to setup CR on a Raspberry Pi. The unfortunate and difficult part of this is that most of it has to be done headless since Blender can't open the UI on a Pi. I've installed Blender and downloaded the .zip of the addon. Looking online, i've found some instructions to create my own .py script to install the addon for me. import bpy bpy.ops.wm.addon_install(filepath='/home/pi/Downloads/cr_022_bl280.zip') bpy.ops.wm.addon_enable(module='crowdrender') bpy.ops.wm.save_userpref() This seems to work as far as blender is concerned but this is what happens when CR tries to install. (sorry for the formatting) TLDR: ImportError: CrowdRender is not able to run because it can't import necessarycomponents, please e-mail us at [email protected] to report this. I know you want me to email you but I thought documenting it here might help some folks who have the same crazy idea as me! pi@raspberrypi:~ $ blender -b -P install_cr.py Warning: Falling back to the standard locale ("C") addon_utils.disable: crowdrender not disabled.
