recently I upgraded to 4.14 from 4.13.2. That did messup some of my workspace but nothing I cant handle.
Unfortunately I wanted to test the mesh distance field capabilities, and it completly broken all my Skeletons. Dont know how and why. In example my mixamo characters all have wierd shadow effect, and my mannequin is partialy transparent.
Yes - I did check the material settings. unless there is a new trick to 4.14 I dont know yet?
I also tried to manipulate the light sources, and obviously turnign the distance field off.
Rebuild the project and restarted the editor several times.
