• First, expand the character on the stage menu and navigate to their Looks folder. Example - /World/male_adult_construction_03/Looks.

• Next, select your target material (Example - opaque__plastic__hardhat) and change material’s Property -> Material and Shader -> Albedo -> Color Tint value to adjust character’s color.

April Tags

We provide a simple mdl material that can index into a April Tag mosaic image.

To use, add the material to your stage using Create->Isaac->April Tag-> or by dragging the following material into the stage from the content browser

/Isaac/Materials/AprilTag/AprilTag.mdl

Then create a mesh cube using Create->Mesh->Cube and assign the AprilTag material to that prim

The material has the following parameters which need to be configured:

• Mosaic texture The path to the texture that contains the grid of April tag images

• Tag Size The width/height of the tag in pixels

• Tags Per Row The number of tag images per row in the mosaic

• Spacing The number of padding pixels between each tag image

• Tag ID The index of the tag to use.

Some sample mosaic textures are provided in /Isaac/Materials/AprilTag/Textures/

The figure below shows example usage using /Isaac/Materials/AprilTag/Textures/tag36h11.png
