How do I use Normal Maps?

I have a GLTF/GLB model with normal maps. How can I make Wonderland Engine render them correctly?

Normal maps are supported in Wonderland Engine, but disabled by default.

Enable them as follows:

  1. Enable Views > Project Settings > Rendering > useTangents
  2. Go to Views > Resources > Pipelines
  3. Right-click “Phong Opaque Textured” > Duplicate
  4. Rename the new pipeline “Phong Normal Mapped”
  5. Enable NORMAL_MAPPING in the new pipeline.

Now you can switch the material of the imported mesh to use the new pipeline and set the normal map.

(And as @yin-chien_Yeap mentioned, make sure to export your model with tangents. Tangents can not be generally regenerated and need to match whatever your normal maps where authored with to look right.)

Note that the model must be exported with Tangents for the normal mapping to work in Wonderland
