Dynamic Digital Humans Documentation
Setting up textures
DDH Tools has its own custom shader editors. If this custom editor for the Head, Hair or Mouth did not import correctly and shows the original editors, then in the Project Menu, navigate to Packages>Dynamic Digital Humans>Shaders>URP>2020 and select the appropriate shader. Then either double-click the shader and click Save Asset or right-click the shader and click Reimport.
NOTE
- For the Head Shader use DDHHead
- For the Hair Shader use DDHHair
- For the Mouth Shader use DDHHead
An example of the difference between the original editor and custom DDH Tools editor is shown below.

Depending on how the character was imported into Unity, textures may automatically be applied with the desired settings. If the character does not have the right textures, then make changes as needed according to settings shown below.
NOTE
For furthur reference on texture settings, watch this video from 7:26 onwards
NOTE
The specific values used for the texture settings in this section (shown in brackets) and the atlas videos are for the LauraV5_01 model. They can be used for your own character model or adjusted as needed.
Open the prefab asset created and change the textures as required.
