Modifying WorldRenderer::getCombinedLight

[FrozenFarmer64]

I have been messing around with custom lighting for a Minecraft Mod and have been running into some roadblocks in changing the light value of a block. I am trying to make a block render darker than the world light value. Does anybody have any ideas on how the result from WorldRenderer::getCombinedLight could possibly be changed?

You cannot do that. Minecraft's chunk format enforces the range of [0, 15] light level. Forcefully changing this will cause world corruptions and a lot of incompatibility with other mods.

 

However, if the darkness effect is only visual, then you could create a custom shader to achieve it.

I think I misunderstood. Are you trying to render a single/few blocks that way? Or do you want the whole world to be rendered that way?

@DavidM--I want to render only a few blocks that way, if that helps the situation. I don't even want to extend that [0, 15] light level limit, but I was just hoping to lower the light value of some custom blocks by changing their light value in broad sunlight.
