## **What is possible**

---

V-Ray can render XGen primitives in IPR as well. Anything that can be done to a scene for a production render can be done while using IPR too. This includes

adding/removing patches to/from descriptions  
adding/removing descriptions in the scene  
moving the original geometry (patch) that XGen primitives are instanced on  
changing XGen attributes to change the instantiation of XGen primitives  
changing the custom shader parameters (which are just custom attributes)  
changing description properties (primitive type, primitive generation, etc.)  
playing with modifiers  
assigning materials to patches/descriptions  
modifying assigned materials
