TileMapLayer3D

Version 0.5.0 - New UI, Toolbar and Data model (If you use versions before 0.4, this will break old scenes). Migrate to 0.4 first then to 0.5

2D to 3D level and asset Creation. Inspired by the 2D TileMapLayer node. This Plugin allows you to create 3D levels with 2D Tiles and Textures.

You can paint and erase as you would in a full Tiling and Level creation system.

It supports Collision and exporting the Level and Assets as separate meshes.

Allows tiling across all 3D axis, with a perfect grid-based structure.

You can also create Objects and reusable assets with this plugin.

Auto-tiling is stable, but Requires 3x3 (minimal) TileSet with 47 Pieces (uses same Terrain configuration as TileMapLayer nodes for 2D)
