Overview

Combines multiple rule-tile assets, such as grass, water, and roads, so they can all be painted on one canvas. It is the gathering point that turns one-terrain-per-node assets into a set for map production.

Usage tips

The standard multi-terrain setup is autotile_from_* (grass) + autotile_from_* (water) → rule_tile_merge → rule_canvas. Terrain chips then appear in the editor.
Give every asset a meaningful material_id, such as grass or water, before merging. Defaults are automatically renamed and can become difficult to identify.

Related nodes

autotile_from_parts / autotile_from_template — generate assets to combine
rule_canvas — consumes the combined result
rule_tile_asset_save / rule_tile_asset_load — save and reuse assets

What this node does

Each Autotile creation node makes one terrain type (one material ID). To paint several terrain types such as grass, water, and roads on one map, combine the assets here before connecting them to Rule Canvas.

If material or tile IDs collide, for example when both remain at the default terrain, IDs in later assets are renamed automatically, such as terrain_2, and a warning reports the change.

Example wiring

Autotile creation (grass).asset ──→ RuleTileMerge.asset_a
Autotile creation (water).asset ──→ RuleTileMerge.asset_b
RuleTileMerge.asset               ──→ RuleCanvas.asset

After merging, both terrain names appear as chips in the Rule Canvas editor and can be selected for painting.
