If using Maya 2011 you can simply put Input to say sRGB, meaning that all your textures you plug in are handled as gamma corrected, which is the same as using the gammacorrect node.
Then under Output, you put it to Linear. Using a exposure_simple node on the camera is recommended with gamma set to 2.2.
The 3ds Max 2011 Subscription Package obviously comes with iRay support, and by support I mean some kind of GUI to control it all, at least thats what I heard.
but for color swatches you still have to gamma correct them right? for mia material, etc … I dont think the color management take into account color swatches … I might be wrong, correct me if I am…
Also do you still need to add the mia exposure simple even when you use the color management?
what I do when Im in the render view I go to Display > Color Management then
Image Color Profile > Linear
Display Color Profile > sRGB
Im wondering if with this setup you still need the mia exposure …
thx.
I am copying this from the maya 2012 thread.
Got iray working in 2012
Seems much improved over all. I haven’t pushed it too hard but it seems they have made noticeable improvements to iray.
Here is how I got it working,
Copy the required dlls from another package that has iray with mental ray 3.9 (max 2012 in my case). Put them in the your maya2012\bin folder.
cudart64_32_7.dll
libiray.dll
libiraymr.dll
Now iray is installed, to activate it I use a slightly modified k_progressiveRendering script written by Sylvain Berger. I attached my version if his script.
Works fine on my 2 x gtx470 rig.
The script that I attached before gives you control over iray with a cute window. It makes iray a check box, there is also min samples, max samples, max time, and error threshold in there too.
Works on my 1 x gtx470. Iray from MR 3.8 never did work for me (fermi compatibility?), but iray from MR 3.9 works really well.
hi , if i active the irradiance particles and i have a crash , i just active in render render settings-options-diagnose bsp- size, i have the bsp2 and the version 64 bits for maya 2011
You don’t need an indirect lighting method with iRay. It is a path tracer and does that automatically on its own. Turn off FG, GI, IP, etc. It’s unnecessary.
too bad there’s no demo of mental ray standalone so I could try this out on OS X. Would have been nice to use as a benchmark for the Quadro 4000 review I’m just finishing up.
Hey cgbeige, please link us to the quadro 4000 review when it’s done, I’m interested to read what another cg guy has to say about it, I actually own one.
Thanks!
Well i’m pretty much done with my assessment (I’m reviewing the Mac edition). It’s a huge improvement over the 4800 and the drivers, while still shitty for viewport 1 compared to the Windows drivers, are very good with vp2. It got the same score as the radeon 5870 for a large scene play blast and the msaa doesn’t cause a big hit. There are some bugs and opencl is still AWOL but that’s coming. I like it for sure - two of them with VrayRT would be cheaper than a 5000 and has more cores and it’s great that they didn’t go apeshit with a Mac-specific card (it has a little sticker on it saying Mac version) so the price is the same as the Windows version, which has always been an issue with Mac cards until now. I just hope we don’t have to wait for 10.7 for opencl support (the betas have this but the viewport is unusable in Maya with the 10.7 betas). New GL 3.2 implementation so that’s to be expected.
But I’ll put the link yo the full review in my sig later.
Sorry rBrady, where did you attached the script? i can find it, probably i’m blind
i have questions about some problems ,
got almost everything resolved thanks to the answers in the other thread
i am asking here as this is a more iray centered thread , and that may be more people would chime in with suggestion .
i did install the script : fine
turned off the frame buffer mode : fine
i can now render with iray
the problem is that my ipr crash everytime it try to refresh
3 questions :
thank you for any light that could be shed into this matter
Hey xtrm3D
I was testing iray with a work colleague a few weeks ago on maya 2011. Yeah we also experienced those same issues. I guess it stems from iray not being propperly intergrated to maya yet ?
I would like to know if the same crashes happen on 2012.
Sorry, I forgot to attach my script to this thread.
Its not officially supported at all, so crashes are to be expected. It’s a “use at your own risk” scenario. Try a clean scene with some simple geo first. Its easy to run out of memory and crash the app. Its a bit like going back to the 32bit days.
BTW, I got binary proxies working, they work great. Once I get to 64 trees I run out of memory and it crashes though.

The press release for MR 3.9 said that iRay would support more materials, but so far it seems like it’s still just mia_mats.
Does anyone know if any additional materials are supported?
I’m not getting this to work at all. First off I can only find 1 of the 3 files you’re supposed to copy, the libiray.dll is the one I find.
Using the attached script, I can get the iray Rendering Options Version 1.1-window up and all, but there’s no “PRG”-button in my renderview to easily get the settings up. Also, when I render it, it’s not using the GPU at all, only the CPU. There’s no indication whatsoever in the Render View nor the Script Editor that iray is being used.
