Material Overrides
Material overrides allow you to change the material (or material properties) for an individual actor, without having to change the material itself (which would affect all actors with the same model).
Material override properties can currently not be animated.
To add a material override, go to the actor editor and select the pfm_model component of the actor, then click on Edit materialOverrides. This will take you to the UDM Editor window, where you will have to set up the following data structure:

You can now fill properties with the material properties you want to override the material with another material, double-click the value for the dstMaterial property and enter the path of the replacement material.
You can also replace individual material properties and textures manually by adding them to the properties and textures for the textures accordingly.sections. For instance, if you want to override the color_factor property, right-click properties, select Add Property > vec3 and name the property color_factor. On the right side you can now double-click the value to edit it:
If you want to replace the albedo map, right-click textures, select Add Property > string, name the property albedo_map and input the texture you want to use as a replacement as the value.
