1.16.5 - Custom Light Block is not working when using optifine

[Kikoz]

Hi!

I created a light emitting block which works when I'm not using optifine.

After I run it with optifine the block is not emitting any light. Could someone help me how to solve it? Thanks!

	public LightModel(Properties properties) {
		super(Properties.create(Material.WOOD)
    			.sound(SoundType.WOOD)
    			.hardnessAndResistance(3.0f,3.0f)
				.notSolid()
				);	
	this.setDefaultState(this.stateContainer.getBaseState().with(LIT, Boolean.valueOf(true)).with(WATERLOGGED, Boolean.valueOf(false)));
	}

  
    public int getLightValue(BlockState state, IBlockReader world, BlockPos pos) {
        Boolean i = state.get(LIT);   
    	
        if (i == true) {
        	return 15;
        } else {
		return 0;
    } }
    

    public ActionResultType onBlockActivated(BlockState state, World worldIn, BlockPos pos, PlayerEntity player, Hand handIn, BlockRayTraceResult hit) {
    	{
    	    if (Screen.hasShiftDown() == true) 
    	      {
    	           state = state.func_235896_a_(LIT);
    	           worldIn.setBlockState(pos, state, 10);
    	       } else {
    	    	     return ActionResultType.PASS;
        }
     }
    	 return ActionResultType.func_233537_a_(worldIn.isRemote);
    }

Allright managed to get it work by using

	.setLightLevel((lightLevel) -> 15)
