I don't think SurfaceBuilder is what you want to look at, as that only builds the surface. Probably check out ChunkGenerators, I see in net.minecraft.world.gen.GenerationSettings there is a defaultBlock field that seems to default to stone. *edit: looking a little bit more, it almost seems as if the default block is determined by the dimension as opposed to the biome.

Look at vanilla recipes for examples, and also https://minecraft.gamepedia.com/Recipe#JSON_format

No problem, that's why I didn't simply say it wasn't compatible!

Go back to the optifine download page and read the changelog for the version you downloaded, it tells what versions of forge, if any, are compatible with it.

Please post logs as described in the EAQ, otherwise it's just guessing

Nope, gradle.properties, came with the MDK, only contains this: but I saw somewhere someone mentioning you can target your JDK through an option in there, I just don't know what it is myself, I only have Java 8 installed.

Uninstall java 13, set JAVA_HOME (I think), or I believe you can set options in gradle.properties to specify the JDK you want to use.

What is the output of java -version ?
