This displays settings for the Painter editor window, some of which are duplicated by the Option buttons at the bottom of the window. Hide Info Messages: When checked, Painter won't show informational messages even if the Toolkit’s Configuration Dialog’s “Inf...
Paint Mode Basics
The left column always displays a list of Tilemaps. Select which Tilemap that you want to operate on. The center column displays sources of Objects to paint. Select the source of Objects. Then the right column displays the contents of the selected source as a...
Object Sources
The center column is a resizable split view. The top part displays all possible sources for painting Objects. Sources can be any Palettes that you’ve created with the Unity Tilemap Editor, TileFabs, Bundles, and Favorites. Painting on a Tilemap requires a sel...
Favorites
The Favorites List operates in conjunction with the Clipboard and the Pick tool. New items are always added to the top of the Favorites list. Use the “F” button to add the Clipboard Object. This isn’t possible for TileFabs or clone-state TilePlus tiles. CT...
Palettes
If you want to omit a certain Palette from the list, change its GameObject’s layer to anything other than default. To omit a TileFab or Bundle, set its IgnoreInPainter field to true in an Inspector. When Show Palettes is checked, the Use Unity Palette checkbox...
Painting Prefabs
Instantiated Prefabs are always parented to the selected Tilemap and set to the same layer. You can use transform modification shortcuts like ALT+V, ALT+R/T/X/C/Z when previewing Prefabs. This does not affect the Prefab asset at all: when you release the mouse...
TileFabs, Bundles, and Chunk Snapping
Recall that a Bundle (TpTileBundle) asset is an archive of a single Tilemap and a TileFab (TpTileFab) asset is a collection of Bundle assets. To exclude a TileFab or Bundle from Painter, inspect the project asset and set the IgnoreInPainter field to true in a...
List of Objects from Selected Source
The right column is also a resizable split view. The top part of the split lists the Objects from the Source that is selected in the center column or the optional UTE palette view when the Source is a palette. When you click on an Object in the List or Palette...
Basics
The left column still displays a list of Tilemaps. When you select a Tilemap in the left column then the center column will display the tiles in that map along with thumbnail images of tile sprites and their positions, followed optionally by the tile’s Instan...
Selection Inspector Variants
For TPT tiles you’ll see Selection Inspector shown in various images in these docs. Tile tiles (normal Unity Tiles) are assets so you can only open an Inspector on the asset. Listing all the positions for a Tile might make the list thousands of items long, whi...
Working with Painter's Grid Mode
This pane is used to organize Grid Selections. When this panel is open you can capture Grid Selections with the UTE or from within Painter. What you see in the list are BoundsInts from Grid Selections. The BoundsInt is all that’s needed to create a new Grid S...
Painting
Getting Started Enable Painting objects by clicking on the Paintbrush icon in Paint mode. Select a Tilemap to paint on in the left column. Select a source of Objects from the center column: a Palette, the Favorites List, a TileFab, or a Bundle. Select a speci...
Modifiers
Custom Modifiers are “presets” and are applied with a shortcut key, defaulting to ALT+V (Win) or Option-V (Mac). This works in conjunction with an Editor window cleverly named “Painter Modifiers,” available from the Tools/TilePlus menu or by clicking on the P....
How Different Tile Types are Handled
Painter expects to encounter one of two basic tile varieties: Tile and TileBase. There’s actually a big difference between the two. A Tile has a sprite, a transform, and a Color. All tiles derived (subclassed) from Tile have these characteristics. However, a T...
Chunk Snapping
This is a special mode that’s useful for painting TileFab “Chunks” aligned to a grid equivalent to the size of the Chunk. Chunks are a specific sort of TileFab that’s always square and of even dimensions (4x4, 8x8 … 64x64 etc.). It’s activated by the Chunk Sna...
Prefabs
In Paint mode, the center column has an option checkbox called: Bundle Tiles View. This checkbox only appears if the “Show Tile Bundles” checkbox is checked. When unchecked, the Bundle is painted as a single item as usual. When Bundle Tiles View is checked, ...
Decomposing a TileSet
Perhaps you have a TileSet that you bought on the Asset Store, Itch.io or somewhere like that. Often you need to paint more than one tile from such a set to create a complete visual object in the scene: a building might comprise a dozen or more tiles or someth...
Appendix 1: About the Icon
Painter will try to create an icon for you when the Clipboard contains a multiple-selection Pick and you choose to create a Bundle or add the Pick to Favorites. A customized sprite packer is used to create a representative Icon (aka sprite) for the TpBundleTil...
