🖌️Object Brush

Object Brush is a tool that lets you paint prefabs on surfaces. This tool can be used painting environments, general objects or anything else you can imagine. A great tool to have in your arsenal!

Make sure that you have Always Refresh on in the Editor when using the Tool.

To get started using Object Brush Tool we need to create a holder for our particles.

We refer to a particle as one prefab/object that is spawned at a point we paint.

1. Create a GameObject in the hierarchy.

2. Attach the Object Brush Tool script as a new component.

All properties has tooltips if you hover over them in the inspector that tells you what they do.

Update Mode

This handles when the objects we paint should update and recalculate everything. It is very important you understand when you can use each of the Update Modes to avoid any freezing when painting later on

The painter tool never lags or freezes the game, only in the editor when modifying it.

Update Mode Auto

Updates whenever you change any of the properties in the inspector. Use this carefully.

Update Mode Manual

More information about keybindings are available in the same inspector window as the Tool itself.
