Operating system: macOs Mojave Version 10.14.5
Graphics card: Intel UHD Graphics 630 1536 MB
Broken: (example: 2.81, 2.81 2019-11-27)
In object mode I select Armature first and mesh second. Change to Weight Paint and the mesh has the color code (green). After I select a Bone with Shift + LMB the color code for the mesh is away (grey).
Exact steps for others to reproduce the error
I am following this tutorial: https://www.youtube.com/watch?v=nK0nRAMSRZQ
It's in version 2.79 and without screencast keys (horrible :D). I'm at minute 5:30 - 6:00 where he's weight painting some vertices.
I hope it's just a thing of settings like in 'View'.
If someone has a better tutorial for rigging a rolling and bouncing ball, you're welcome to share the link with me :)
Thanks for help
