Before and after

[Zach Gray]

Here is my test scene.

The fur has basic styling. Nothing fancy with shading yet. And the size isn't tuned, etc, etc.

Turn hairs from 500 to 10 or 15k.


I can recreate this with both of my installs with a simple sphere:
x64 2.25ADV 2013 from Jan7 and 2.21EDU release.

I can render 100k's of hairs +GI in 30s with a plane with Hair3, but anything else crashes with more than a few hundred hairs. I've increased the memory, changed geo to static. Its true of both the vrayShave.dll shader and Hair3, which makes me think it's the ShaveSh.dll

(Network install, setting env variables via python, BUT I also did a local install to make sure that wasn't the issue)

Thanks for taking a look.

Im working on an asset right now (furry animal) everything renders fine...did you put those shave dlls into vrayplugins folder?

[Zach Gray]

Yep. I've tried just about everything I can think of including installing locally instead of network location and disabling most other plugins. Are you on win7 or Linux?

[Morbid Angel]

on win 7 x64

i just notice that joe returned the ver for vray shave to 15

Shave for Vray:
Click here for the Win32 (last update 7.0v15)
Click here for the Win64 (last update 7.0v15)

EDIT:

Just heard from Joe,

I've got the right plugins running, but still, I'm not getting anything stable on non-planar surfaces.


ORIG:

I'm going crazy here. I've tried everything I can think of, but I can't get shave to work with vray. There is something funky about my install.

I've literally spent 10+ hours trying to get this to install and work properly. Joe has been helping as well, but he can't reproduce the error.

-vray 2.20.1 Win 7 x64

-Maya 2012 Subscription Adv Pack sp1


For my attempts to fix, in case you were curious:
No plugins, no scripts, no network install of vray, no network install of shave, default locations for all installs(clean), running as admin, clean maya.env, clean path, clean environment variables, changing dynamic memory, checking dates on vray_shave.dll and ShaveSh.dll files, running shaveDiag(), launching from a custom python shell to clean env, deleted EVERY other copy of .dll files from network and hdd, rebooting to ensure no leftover open file handles. What is strange is that it's the same for 2013

[Morbid Angel]

have you tried running this setup on another machine? Also Im sure you did but just to check have you cleared out your maya user prefs dir?

This means the problem still exists?

[bazuka]

FYI

joe has just rlsed v17

cheers

[Zach Gray]

This means the problem still exists?

I had posted a solution to the problem related to hyperthreading, but Joe got in touch with me and said that wasn't the real fix, so I pulled my post so I wouldn't confuse anyone else who might be having the problem. I think he's found where the crasher is, and is actively working on the fix. .17 didn't fix it completely, but fixed some other stability stuff as far as I know.

[Morbid Angel]

yeah since v16 I can have multiple shave nodes in one scene and multiple maya's with shave running...so things are getting better...hopefully.

Zach, just tried your file with v18, 50000 hairs and no problems at all - renders in 18s

Best regards,
Vlado

I've been in touch with Joe. It's a machine specific bug, probably due to multi-core stuff. (The v17 and v18 shave versions were trying to track down the bug) I've tested it on another machine, and it works great. Disabling hyperthreading also makes it work, but he's trying to track down the root cause.

This is the machine with the trouble for the sake of interest:

System Manufacturer Hewlett-Packard
System Model HP Workstation z620
System Type x64-based PC
Processor Intel(R) Xeon(R) CPU E5-2630 0 @ 2.30GHz, 2301 Mhz, 6 Core(s),

This explains why it works on my main workstation better then on another one, one has HT off the other does not.
