Gltf "RealTime" does not work as expected
According to comments in this topic
I think this deserves a "split"
I came across the same issue, unable to edit gltf either on the fly or by build all/Close project e re open
BUT i noticed that the feature Is broken only for older models.
I slammed a fresh One in the project and i could edit the latter as before
Also noticed in console a info regarding changes from gtlf version 6 to 7 (could be something different, forgot to write down details)
My bet by now Is removing the _Packint (and packages) folders from the main project could solve the issue, (unable to debug at the Moment)
