Description:
When rendering a scene and sharing the result in the Blender cloud from the menu Blender does everything and opens the browser with the cloud webpage with the image in theory, but in reality the image cannot be seen.

This is the result:

https://cloud.blender.org/p/home/5accc81c83aa13432a34abdf?t

Dr.Sybren identified the problem being the render oputput being EXR, and it being not supported by the cloud.

Exact steps for others to reproduce the error
Configure the render output as EXR
Render the scene
Upload to the cloud.

Proably it would be better if the result gets converted to PNG internally before uploading it to the cloud if the cloud does not support EXR.

It looks like Pillow does not support EXR images. Therefore we can:

  • either install OpenEXR and numpy to convert the image to PNG or JPEG with proper gamma (see example)
  • or, save the image as PNG or JPEG via the Blender Cloud add-on in Blender and upload that to the Cloud

I think it's a good idea to go with the second option and look into getting numpy and OpenEXR added to Pillar when we need it for an additional use-case. Any thoughts, @Sybren A. Stüvel (sybren)?

I agree, Blender can easily save a file as JPEG in some temporary location before uploading.
