The project in the latest version of spine looks like this ↓
After importing it into UE 5.2 it looks like this↓
Lit Material With Shadow On↑
Lit Material With Shadow Off↑
Low Alpha value↑
Tried different export settings (pma on/off, bleeding on/off, both on/off, different runtime format) and none of them are working. The black outline still remains.
Really need some help here. Thank you.
