Help

Hi there,

I use Godot 4.2.1.stable version, with default settings (I didn’t want to mess up things).

I am using subviewport in my project, and, for some reason, i keep getting this deep dark shadows and i don’t know how to solve this issue. And the same model has normal shadows when not in subviewport

Thanks for any help.
