### **Example: Dynamic Tessellation**


## **Notes**

---

- Use the **Ox Render Settings** modifier to control the thickness of the strands; any settings in the Ornatrix atmospheric effects are ignored.
- Unless you use the **Use global hair tree** option, the generated strands are dynamic geometry; as such, they respect the **Dynamic memory limit** setting in the V-Ray raycaster section. If you have lots of hair strands and **Use global hair tree** is disabled, it is recommended to increase this value.
