I recently installed Up Studio 220.127.116.117 and then 18.104.22.1687 a few weeks later.
While all else is working perfectly I cannot get into the material editor. Clicking from within Upstudio-
It simply opens as a blank empty white window (see attached)
I have even tried opening the matdef.exe file directly with the same result, running it as “administrator”, installed latest video drivers etc.
laptop is a HP Elitedesk 8460p
Any suggestions on how to fix this would be greatly appreciated.
