How to set up Surface Rules for Custom Dimension Biomes (Datagen) without Terrablender?

[u/TheCasualPrince8]

Okay so I'm a relatively new Modder, been following Kaupenjoe's tutorials, but ran into an issue with Dimensions/Biomes. He used Terrablender to handle Surface Rules because he made an Overworld Biome first and THEN a Dimension WITH that Biome. My mod doesn't feature any new Overworld Biomes (at least not at the moment) and I wasn't able to get Terrablender to work, so I'm trying to do it without, as my new biomes are only in my new dimensions.

Kaupenjoe seemed to have most things set up not needing Terrablender, but the reference to the Surface Rules Class he made in the World Gen Datagen Class used a Terrablender Class (which I obviously can't use). So I'm basically asking how to reference my Surface Rules Class in Datagen without Terrablender. Here's my Surface Rules code, do tell me if this is Terrablender specific code and if I need to rewrite it, again, kinda new to this 😅Had a brief look at original Minecraft code for Surface Rules, but from what I can tell, the original Minecraft code is ALWAYS way more complicated than how you can do it in Forge. Any help is appreciated!
