Thank you for checking it out so soon and providing the example.
If we are getting a somewhat consistent yet still faulty behavior that's still a step forward in my book, hehe.
It appears to me I may have simply forgot to set "hasAlpha" to "true" again when using the "Set mesh texture" action.
Therefore I have updated the download again (same version). Please just get it again and replace the main plugin.
In my brief testing as far as I can tell things do work actually correctly.
Oh I saw you mentioned a "bonus bug" relating to a behavior camera which I will look into also. In general though let me mention that I highly recommend for most scenarios especially regarding your main game camera to use cameras created by the main plugin instead. There are issues with behavior cameras that do not affect regular cameras.
