I tried to open the Multiball Rig in Blender 2.8 but i won´t open its just an empty Blender file.
Hi Jens,
You might be opening the2.78 version, try this one https://cgcookie.com/resource/multiball-rig
That is the 2.80 version.
However, if you are taking the bootcamp course, the 2.8 files are also available to download. (check the source files and download the ones that have the 2.8 prefix.
I can´t open the MultiBall_2.80.blend file (so definitly not the 2.78 file…) contained in the 2.8 source files of the course either (using blender 2.81) . Error message says that file format is not supported (???). When I open the file from the explorer (without Blender running), it will not give an error message but will just open a blank project.
However, the file from the "resources" link in your answer works fine...
Obviously one of these strange things...
