I did some repair work on my custom textures last Friday. I started getting strange error messages when I loaded them. Originally I thought it was that I had textures that were too large but after selectively removing and replacing textures I discovered the problem was in some very small (1 Kb) files.
I also learned that you can play with the texture files in the custom material folder WITHOUT having to close and re-open 20-20 design every time. You DO have to close whatever 20-20 windows you opened to get to the Custom Textures.
If there is a problem loading a Custom texture then you can find out right away.
If you get an OUT OF MEMORY error when loading the custom textures then you do to RESTART 2020 design. Otherwise you can drag-n-drop, copy and paste the custom materials freely.
