Biomes

A typical biome file breakdown. This page specifically is going to explain the default, parameters. these parameters WILL be covered in the elsewhere the same. this is a quick start

This page has not yet been updated in accordance with the new structure. Most information should still be valid, but keep this warning in mind.

The information below is a variant of the Biome tutorial, and we would recommend that you familiarize yourself with that first. this would then make more sense especially the complexity will become less complex.

Parameters:

• Name - What is the biome called in-game, filename refers only to what internal schema know

• Layer - What blocks makeup the biome floor, and sub-terrain (not including caves)

• Objects - This lists the 'things' that you want to place all over the place eg: trees, rocks, etc...

• Generators - The way the terrain Height-map is designed

• Derivative - This sets the Vanilla Color, Mob spawn, Weather, and some other event

Many of these here will give you a world that 'looks' like a normal world, but Iris is able to give you so much customization that you can have many types of variants that can look otherworldly.

These are some examples of other uses of the defaults:

Mars Cliffs

Recap:

Much of what you have seen above, IS used in the example projects, when it comes to what a final project biome looks like, they would look like something like this

Post Overview

We highly recommend that you familiarize yourself, and toy around with them before diving straight into the heavy lifting- that is, advanced biome manipulation. Biomes are the some of the most important parts of this plugin. I don't think i need to explain how important that the biomes are, please familiarize yourself with Vs-code and make a custom biome using [this] to do so; once you do that feel free to dive into the harder parts in the next page. Good luck, we hope that you make a world of your dreams.
