This is why "bedrock" (aka the non-JAVA) version can do this, and not the Java version. You can get away with some "super-bloom" hacks to Java Minecraft, but that is not ray tracing, and that's also why heavily modded Minecraft games break so easily. However, it would make far...
In the infinite worlds of the Java and Bedrock Editions,the Nether is also horizontally infinite. In Bedrock Edition, the build limit in the Nether is 128 blocks, despite it being 256 in all other dimensions. The Nether has no daylight cycle and no weather. Can you survive in the nether?
