XGen hair not rendering with DR enabled in V-Ray 7

V-Ray V-Ray for Maya Issues
1

XGen hair will not render when DR is enabled. (It doesn’t matter whether there is a render server or not.)
Tested with V-Ray 7.10.02 and Nightlies 7.10.03 (Maya 2025/2026 win11)

The following warning will appear:

[18:39:39.414] Warning : GeomMayaHair pPlane1_description4Shape@collection3@description4 @xgen_patch: map channel Bison_Tip_Color (2) at time 1.000000 should have 0 strands, but has 251 strands

Has Chaos support seen this post?

I’ll take a look today. Sorry for the delay.

Tested it on a simple scene, and it seems to work properly. I guess it’s something specific. Mind if you attach/send the Maya scene?

Sorry for the late reply.

Here’s a screen capture.

I’ve attached the Maya scene data (I don’t know if it makes sense)

Thank you. The issue is reproducible, and it appears to affect only the “Use Local Host” option in DR. I’ve logged it (internal tracker ID: VMAYA-13684) for dev investigation. For now, disable the “Use local host” option when using DR to render xGen.
