Modifying WorldRenderer::getCombinedLight


Recommended Posts

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?

Some tips:


Modder Support:


1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code.

2. Always post your code.

3. Never copy and paste code. You won't learn anything from doing that.



Programming via Eclipse's hotfixes will get you nowhere

5. Learn to use your IDE, especially the debugger.



The "picture that's worth 1000 words" only works if there's an obvious problem or a freehand red circle around it.

Support & Bug Reports:


1. Read the EAQ before asking for help. Remember to provide the appropriate log(s).

2. Versions below 1.11 are no longer supported due to their age. Update to a modern version of Minecraft to receive support.

@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.
