In WPF, you can set multiple material effects for a 3D model.

The 3D model in WPF mainly uses its own lighting material to reflect the three-dimensional and spatial sense of the model. We usually use a brush as the material to assign the model. Here, WPF provides several material types, for example, the foreground material of the model is diffusematerial, and backmaterial (if our foreground material has transparent properties, we will see the background material, A bit like a layer mask concept ). Next I will give an example to achieve the dual-material effect of a model.

First, set the foreground material and add a highlight material. Here, our foreground material is an image with a transparent background ()

Set the model background material. You can set images and videos to a brush ()
