For the material I could get only simple lambert to work.
No reflection or refraction.
For Iray? You have to use the mia_material. No problems here to get reflection working.

That's interesting thanks for posting all the info - wouldn't even have tried iray.
I found this 3dsmax dll ( ) and you say that just the -cudart64_32_7.dll is there, but i found all the three of them in the Autodesk\Softimage 2012\Application\bin directory !
maybe they are the same and we can just put it in the /nt-x86-64/
It looks like you don't even have to, at least here installing the ctrl_ghost geoshader was enough to get iray working.

So far, textures have not worked at all for me (results in an error and black render). Has anyone else had any luck?

There's also a lot of fireflies (bright white pixels) that don't seem to go away no matter how many samples I put.

are you using softimage's image node ?

Just a thought, did you try to use the native image shader of mental ray, mib_texture_lookup ?

Only the .mi based version of mia_material is supported (The one with the ugly UI)

Is there a way to make iray use both CUDA and the CPU?
It seems all CPU power is wasted when using CUDA and vice-versa.

i didnt manage to have iray use full both cpu and gpu, in 2011 it only used CPU, in 2012 it only uses GPU, i think there must be some string option to tell it to use both.

and yeah, only mia_material is supported by iRay, any warning you get from iRay is mostly because the node you are trying to use is not supported.

can be activate in 2011?

If it is so relative simple, why AD don't implemented this natively?

I must be doing something wrong. I've installed the various files as instructed earlier in the thread, but iray doesn't show up as a rendering option. Also, I'm not sure where to find mia_material. Pardon my noobishness!

Can't help you with your iray woes, but the "mia_material" should be available from the "Render Tree Preset Manager" under the category "mental ray > Material"...
Stay safe, sane & healthy!

use Architetural instead of mia_material. It is actually the same shader under the hood, but with a humanly readable interface ;)
good luck

Has anyone managed to get iray to go above 1000 samples?
Basically iray seems to stop when it reaches it and no matter what i can't make it continue in order to get rid of the grain :(

This is what is happening:
' WARNING : IRAY 0.12 warn : non-physical gamma value used in mia_exposure_photographic
' INFO : IRAY 0.12 info : increasing fragment size to 1646k to improve total performance
' INFO : IRAY 0.12 info : decreasing fragment size to 823k to prevent timeout
' INFO : IRAY 0.12 info : increasing fragment size to 1646k to improve total performance
' INFO : RC 0.4 info : progressive: stopping rendering due to max samples constraint
' INFO : RC 0.4 info : progressive: total rendering time was 180.46 seconds

Just read that in Mental Ray 3.1 there is iRay 2.0 ...

http://docs.autodesk.com/MENTALRAY/2013 ... l#whatsnew

"iray 2.0
The iray version 2.0 is a major update of this rendering mode built into mental ray. It provides numerous improvements in performance and quality, like native support for BSDF layering in the rendering core. This version is using the latest release of CUDA, thus it is supporting, and will actually take benefit from, most recent GPU hardware, like the NVIDIA Fermi architecture."

Anyone knows if this will work in SI too?

Actually I didn t expect it to be integrated by AD... its AD at least ;)
The question was more about integrating it "by hand"....like before...
