Hi, just wanted to give a quick update on this issue. We have some legacy code that reflects the material for the assigned default material slot. As a result, the default material does not know which subtype it is referencing when pointing at the default material (although it does work for any subsequently assigned materials).
I have a fix, but it fundamentally requires a restructuring of a significantly large part of the way we map UEFN assets to verse. It’s a WIP and we will get it resolved asap, but just wanted to let you know it may be a few months before this is fixed due to the significant size of the codebase we have to reconsider (although this will also help with several other bugs, so it is something we need to do asap). Apologies for the inconvenience.
