Getting Started With Polybrush

First time using Polybrush? Start here for an overview of the essentials.

Questions or Concerns? Please let us know via email or on the forum. We'll be happy to help!


1) Open the Polybrush Window

From the Unity menu bar, choose Tools > Polybrush > Polybrush Window. This opens the Polybrush Window, which you will use for 99% of Polybrush functionality.

2) Choose a Mesh to Edit

Polybrush will automatically work on any mesh, but for now we'll use a Unity primitive mesh.

To create a Plane primitive, in the Unity menu bar choose Game Object > 3D Object > Plane

Plane

You can also use ProBuilder meshes for an even more powerful workflow!


3) Sculpt Your Mesh

Let's make this mesh look more interesting!

  1. Activate Sculpt Mode by clicking it's icon (sculpt) in the Mode Toolbar.
  2. Hover your mouse over the Plane, and Left Click to "pull", Shift Left Click to "push" geometry.
  3. To smooth out hard edges, activate Smoothing Mode (smoothing) and brush the mesh with Left Click.

4) Paint Pretty Colors

Danger, Danger! The default Unity material won't show Vertex Coloring, so let's create a new material that will:

  1. In your Project Panel, right-click and choose Create > Material, then give it a really cool name
  2. With the new material selected, look at the top of the Inspector Panel- see that drop-down labeled "Shader"? Click it, and choose Polybrush > Standard Vertex Color
  3. Apply this material to the mesh you'd like to paint

Hey custom shader people! You can use any shader, as long as it supports vertex colors

Now we're ready to paint vertex colors:

  1. Activate Color Painting Mode by clicking it's icon (color-painting) in the Mode Toolbar.
  2. Click to select a color from the Color Palette buttons at the bottom of the Polybrush Panel.
  3. Hover your mouse over the Plane, and Left Click to paint, Shift Left Click to erase.

5) Blend Fancy Textures

Texture Blending requires a special shader- you can create your own, or use ours:

  1. In your Project Panel, right-click and choose Create > Material.
  2. With the new material selected, look at the top of the Inspector Panel- see that drop-down labeled "Shader"? Click it, and choose Polybrush > Standard Texture Blend.
  3. Apply this material to the mesh you'd like to paint.

Prefer your custom shader? You can use any shader with Polybrush - see Writing Texture Blend Shaders for more information.

We can now paint and blend textures on the mesh:

  1. Activate Texture Blending Mode by clicking it's icon (texture-blending) in the Mode Toolbar.
  2. Click on a texture in the bottom of the Polybrush Panel to select it.
  3. Hover your mouse over the Plane, and Left Click to paint, Shift Left Click to erase the selected texture.

5) Place Detail Meshes

  1. Activate Mesh Placement Mode by clicking it's icon (place) in the Mode Toolbar.
  2. Click on a Prefab in the bottom of the Polybrush Panel to select it.
  3. Hover your mouse over the Plane, and Left Click to paint, Shift Left Click to erase the selected texture.
