Layers and caves

Order of custom layers

Custom layers are exported in a fixed order, which matters when they overlap.

1. Export → World, tab Custom Layers.
2. Move layers with the up and down arrows. The top one is exported first.
3. The order is saved with your world.

Caves and tunnels

Cave / tunnel layers don’t work

The cave and tunnel layers are known to be broken: corners leave single stone blocks, custom tunnels turn into one huge connected tunnel, walls get textured without air. It’s at the top of the to-do list, but there’s no fix yet.

What works instead:

• Hytale’s in-game cave tool. Shape, floor, walls and vegetation, all in one. Best for small and medium worlds.
• Cave prefabs. Build a cave as a prefab and place it like any other prefab. Air inside a prefab means “leave as is”, so you don’t need air blocks in the list.

Resources layer

The resources (ores) layer is experimental and doesn’t work well yet, it can spread over the whole map. Don’t use it for now.

Read-only layers

Layers marked as read-only can still be changed by some tools in 1.1.0. Fixed for the next release.
