Mcreator 2024.3 - Transparent block casting shadow when smooth lighting is on.

Forge 1.20.1

For some reason my custom transparent block is casting shadow.

Light Opacity is set to 0.

Block has transparent parts checked.

Transparency type set to cutout.

Enable connected sides checked.

Block's visual settings in Mcreator:

Block in game with smooth lighting off (what I want to achieve when smooth lighting is on):

I tried changing transparency types, changing light opacity value (0, 1, 255, 15, -1, -10, -255), enabling/disabling everything in Visual rendering settings and modifying block's code, so far nothing worked.
