Just a warning for anybody loading XRefs on the fly when batch or networkrendering.
When you are using an Hair&Fur effect AND want to use XRefs, the XRefs might not load at render time, even if they are visible in the viewport:
- Put the object with tthe Hair&Fur modifier somewhere in an XRef, and set the Hairs to MR Prims in the H&F effect.
- In the main scene that loads the XRefs, also add the H&F effect, but disable it.
This way everything should work fine. I am working with Max2020, so don’t know how later versions handle this. I didn’t find a clear solution for this anywhere online.
