this object won't render in RT (both CPU and GPU)....why ?

[Subburb]

Hello, i'm doing renderings/previz on an archi project with RT GPU.
All is running fine, except one object : the fences. When i unhide it, RT just stops caused by memory allocation failure. i'm on GTX 580 with 3GB.

it's a simple object (41 000 polys) , with simple Vray material, made of meshed splines, then scattered with railclone (demo), then collapsed into editable mesh.
i've tried reset xform on it, but no luck : this object just stops RT, whatever if it's in CPU or GPU mode.

Of course it works fine with regular Vray render.

here's a link to download the object : http://www.subburb.com/echange/fence_RT_Problem.zip

Hope it'll help to find what's wrong

Was this imported from SketchUp? In any case, I have a fix for this, if you are interested please email me to vlado@chaosgroup.com

It has nothing to do with the number of polygons; the issue is some unexpected (or rather, missing) UV information.

Nope, this object was made into max. if you think it's still interesting to get the fiw, i'll send you an email. Thanks by advance. RT is very addictive

Works just fine with the fix.
btw it's a bit faster with this build (645 KPs with rt2.2.03 and now it's 682 with rt 2.25.01)

Many thanks !
