I created my own custom glass block and when I turn on Smooth Lighting option in game it has ugly shadow inside, that isn't suppose to happen, vanilla glass doesn't have it, how do i remove it and make the block look similar to glass, light opacity was set to 0

on left vanilla, on right custom glass

ok I figured it out, u need to add these two lines of code to your glass block java file and it will remove that ugly shadow inside

first this if u don't have it already

    @Override

    public boolean propagatesSkylightDown(BlockState state, BlockGetter reader, BlockPos pos) {

        return true;

    }

then most importantly this

   
    @Override
    public float getShadeBrightness(BlockState state, BlockGetter level, BlockPos pos) {
        return 1.0F;
    }
