Defect: Surface Comb crashes MAX

Problem

Description:

3dsmax 2021.3.17 with latest ornatrix v7.4.3.32514 (may)

Hi, I'm struggling with this:

Adding surface comb to stack crashes max. It happens when OX GUIDES, Ox Hair from Guides and Ox Strand Lenght has assigned vertex channel. They could share common vertex channel or unique, it doesn't matter.

Steps to Reproduce:

Ussualy problem occurs at point 3:

Create a sphere and add quick hair>fur ball
Assign channel>Paint vertices in OX GUIDES from Surface and paint something.
Add surface comb above Ox Hair from Guides. If it dont crashes yet try to create sinks with mirroring turned on.
If it still working on this step (but very rarely) add vertex paint channel or assing existing one in Ox Hair from Guides, do the same in Ox Strand Lenght.
Crash.

List of stack from top:

VrayOtratrixMod
Ox Change Width
Ox Surface Comb
Ox Strand Lenght
Ox Hair From Guides
Ox Guides from Surface

Jeordanis Figuereo	Hello, I cannot reproduce this crash, but I'm quite confused about the steps to reproduce it. For instance, in step 2: "Assign channel>Paint vertices in OX GUIDES from Surface and paint something." Are you assigning a strand channel or a mapping channel (a vertex channel from the distribution mesh) to Guides from Surface? To what parameter? In the description you mentioned the Length modifier and Hair from Guides but they are not relevant in the steps. I think it would be better if you can attach your test scene here, if are you able to reproduce it from scratch. Jeordanis Figuereo (Product Designer. EPHERE Inc.) LinkedIn Discord
