add this code to blender_init.py seem to solve the issue

def enable_gpus(device_type, use_cpus=False):
    preferences = bpy.context.preferences
    cycles_preferences = preferences.addons["cycles"].preferences
    cycles_preferences.refresh_devices()
    devices = cycles_preferences.devices

    if not devices:
        raise RuntimeError("Unsupported device type")

    activated_gpus = []
    for device in devices:
        if device.type == "CPU":
            device.use = use_cpus
        else:
            device.use = True
            activated_gpus.append(device.name)
            print('activated gpu', device.name)

    cycles_preferences.compute_device_type = device_type
    bpy.context.scene.cycles.device = "GPU"

    return activated_gpus


enable_gpus("CUDA")

Hello Xyene, thank you for providing this awesome tool.

When trying to install (on OSX) using
pip install cube2sphere
I get the following error
Could not find a version that satisfies the requirement cube2sphere (from versions: ) No matching distribution found for cube2sphere
Is this a Python error on my end? Or something that needs to be updated in the project?
I am running Python 5.3.1 with pip 8.1.1

Thanks,
Adam

When I try to stitch together images I've generated from sphere2cube I just get pink output. I'm using blender 3.4. There was a similar issue listed in sphere2cube that seemed to be fixed when i applied this workaround posted by wk39:

workaround

edit
~/.local/bin/pythonXXX/site-packages/sphere2cube/blender_init.py
(installation directory may differ. you can check by 'pip show sphere2cube')

comment out below line

bpy.data.textures[0].image = bpy.data.images.load("%s" % sys.argv[-6])

add new line

bpy.data.images['test.jpg'].filepath = "%s" % sys.argv[-6]

Anyone find a workaround for cube2sphere as well? Should I just try an older version of blender?

Hello Xyene,
thanks a lot for your script

I´m not the most efficient user with coding but will try my best to fix this if there would be a solution

Thanks in advance

On my Ubuntu 20 machine, running cube2sphere seems to open up the blender app, and then doesn't do anything..

Strangely, on my other Ubuntu 20 machine, running cube2sphere works fine..

Any ideas on what the problem might be?

• Ubuntu 16.04
• Blender 2.76b
• cube2sphere from pip

Works perfect! Except the output resolution is always 2048x1024. I checked the projector.blend file and saw that's the default image size. The settings aren't being transferred to Blender correctly. Manually changing the render resolution to 8192x4096@50% worked for my project.

When I provide Transparent PNG files as the 6 face sources. The output does not keep the transparency, it as a black background.

I tried adding "scene.render.film_transparent = True" to the blender_init.py script but it did not do the trick.

Any suggestions ?

When I run the command cube2sphere windows just complains there is no command, script, batch file, etc. It installed just fine with pip but apparently didn't register to any globals to use it anywhere. What do I do from here?

I tried both on Windows and Linux now, and both OS's don't recognize "cube2sphere" as a command, and it's not located in default location where pip instals site or dist packages.

The setup appears to be correct unless there is something I'm not seeing:
