Painting

ctrl + left mouse button to paint

ctrl + scroll to change the brush size

alt + scroll to change the brush density

Make sure that the layer settings in the prefab painter are set up correctly!

Important! The prefabs need colliders in order for the tool to work.

Palettes

Palettes are 'painting presets'. You can for example create a 'Trees' that contains 3 different types of trees. You can manage your palettes using the palette toolbar. You can use the 'Load' button to load a custom palette from your project folder, or you can create a new palette by clicking 'palettes > New Palette'. After you've edited a palette, don't forget to save it. You can relocate or rename palettes however you want.

Compatibility

This tool has been tested with Unity 2018.3.0f2.
