Problem

Description:

crash is caused by width of hair strands turned on in stack, hair is created from curves in maya without ornatrix then converted to hairs with ornatrix it renders wthout width opperator but when added to the stack vray 5.0022 gets an unhandled exception its just hair from guides and hair width in operator stack.

Steps to Reproduce:

create curves from fiber mesh or just create curves in maya  and use curves as guides in ornatrix, add hair from guides to stack doesn't matter if the strands are grounded or not it produces the same error  addd hair width and render turn off or on to see error no width multiplier map was used 

Hi Melvin,

I tested this on Maya 2019, VRay 5.00.22, and the latest Ornatrix V3 nightly build, I can't reproduce the error. It sounds like you are trying to sue the old Render Settings node to set the hair width instead of the new Change Width node(Introduced on Ornatrix V2). Render Settings node has been deprecated and is no longer compatible with new VRay versions. If this is the case, try using the Change Width node instead.
