Hi. SU2017 Make.
It works to use the KT toolbar to import a KT material. Any selected appear in “In Model.” This is not an ideal method.
I have a folder with all the KT .mat.zip files. I have unzipped some of them into folders with their contents. I have pointed SU Preferences … Files … Materials to this folder.
I use Materials … Open or create collection and select that folder. The folder appears as an option, and the unzipped folders show when that folder is selected. I also Add to favourites to be on the safe side. But they sub-folders empty. Even after restarting SU.
What am I doing wrong?
