Creating Materials from PBR Texture Sets

Materials for Multi PBR sets can easily be created when in “Multi-Sets” Mode. When you are in the mode, an orange outline indicates that you are only seeing the diffuse texture of a multi texture PBR set. A right click option is now available to create a material using the entire set.

While the option to create a material is also available without enabling the Multi-Sets mode, it would simply create a diffuse material for each of the images in a set.
