mental ray crashes exporting Hairy, Stand-in objects

[Caveman]

Hi,

I am trying to export a model with Hairs on it, as stand-in, to use as instance with ICE particles.

But mental ray crashes and fails to export. If I remove the hairs, it does the export but I want the hairs too. So, is it possible to export hair as stand-in?

Any help would be much appreciated.

I had to reduce the amount of hairs from 6500 to around 3000 before I could export those hairs. Otherwise either mental ray or both Softimage and MR would crash.

I am on Softimage 2015 SP1 seems like it has unresolved bugs that needs reporting

Hi, thanks for the update,

I found this from here: Mental Ray geometry cache

Hi Origin,

... for example I have a test scene 2011 with over 10,000 instanced characters with hair - rendering will not work as default, the Ram fills up in minutes and crashes but if I make the stand-ins first the scene renders super quick and memory stays around 4 - 6 Gb

Which is related but doesn't necessarily present any problem, or solution (sorry)

But at least it's a sing that it can or should work with lots of hairs/geo, maybe it's version related?

Hey! I got it working.

I think I got the crashes because I had the same material on all the different hairs in the scene. I applied different materials on all the different sets of hair and it's exporting without any crash now

Cool
