I’ve added some checks and dialogs for read and write where applicable. I also noticed a potential issue related to the path of the model. I’ll push an update in the next few days. I’m also in the middle of adding context menus to the scene explorer to add lights and such, so I’ll have to finish that first.
It does also take 2 days for intellij to validate it, so I’ll try to be quick.
Thank you for the report.
