strange Shave&Haircut crash : density map + multistrand

[thekraken]

Hi there,

I'm having troubles with the latest versions of vray / shave&haircut plugins.
os: Mac OSX 10.6.8
maya: 2012 sp1
vray: 2.20.01 (core 2.00.01 ?)
shave : 6.0v71

When using "some density maps" with multistrands, maya crashes at render time ... it won't occur without multistrand, or with hand drawn black&white map.

Here is my test :
- load vray then shave plugins
- create a sphere with default afro hair
- select vray renderer
- set density map with a simple file
- set multi strand count (say 5)
- click render and ... beng !

Any tip or trick to debug things would be greatly appreciated, I can't find a clue in the stack trace ! I cannot attach my tif files, but would be happy to send example textures by any means.

Note that the shave plugin is still reporting as 6.0v33 version, I had to change shaveVersion.mel to load the plugin, and tried to mail Joe about this matter but no answer till now ...

Thanks, we'll check it out, but just to be on the safe side, can you send us a scene for this to vraymaya@chaosgroup.com?

Best regards,
Vlado

Hi Vlado,

I just sent an example scene, with a simple sphere, hairs and two texture files (brokenTex and workinTex), should be pretty easy to test things. I'm not sure it's a real issue, since we do have a complex environment with various maya, vray and shave versions in production ... I hope it's not related to some dyld_library_path misconfiguration etc.

Thanks for your kind help, as ever, greatly appreciated.
