I do not know, rendera is very broken, for example, if you export a model that includes several parts, they will all be at the central point.
I still haven't figured out why the object isn't displayed in the game itself, even though it's in the editor and there are no errors in the console.
At the same time, everything works perfectly in the old plugin. The only thing I didn't understand was how fragliaght8 works, my object is just repainted in one color.
