Hair&Fur doesn't render

[Mnietek2707]

I have a problem with Hair&Fur rendering (mr prim method).
3ds max 2010, V-ray 1.50 SP3a, Vista 64
Very simple scene: geosphere with hair modifier.
Hair just doesn't render.

I found these lines in v-ray log:

Bounding box for "GeoSphere01" is [-111,594,-95,1496,-103,15]-[94,7052,111,15,103,15]
[2009/Sep/3|20:32:01]
Bounding box for "Hair MR Object01" is [9,99998e+019,9,99998e+019,9,99998e+019]-[-9,99998e+019,-9,99998e+019,-9,99998e+019]

I think there is something wrong with values for "Hair MR Object01".
Am I right?

Can you attach your scene? The bounding box message is not an error; it happens because the hair does not have any standard "geometry" in it - it is generated on the fly when rendering.

Hi, I have the same problem here and I would like to know if someone solved that...

Its driving me crazy!

I upgraded my computer, reinstalled everything, and now the fur doesn't render with vray and mr primitives. It's like if it wasn't there, no errors at all. Same in vray frame buffer or in the standard one. If I just create a sphere in a new scene, add fur and switch to mr prim... no fur.

I'm running windows 7 x64 RC on an i7 860 with a gtx275. I am using max 2010 sp1+connection extension and the only third-party plugin is vray sp3a. I tried to reinstall max and vray, but that didn't help.

Fur worked well with the same OS on my old config.

Everything else seems to run fine. Any idea of a solution?

Thanks


EDIT: I found out that running 3ds max in administrator mode makes it work. If anyone has an idea of how I could make it work without that or why administrator mode is required, please post it here!

The Hair&Fur system writes a temporary file with hair information on disk; perhaps it cannot write to this location with your normal user rights. The location of this file should be in a temporary folder and so should be accessible for writing to a regular user account, but maybe something goes wrong there.

It must be something like that. Definitely a security related problem.

Disabling UAC also solves the problem.
