Hello,
I still get warning message for mental ray render even after selecting differnt kind of format apart from maya iff. As mentioned in the discussion above, i even tried using those formats..bt still the error persists. kindly suggest.
Curious, does it happen on a newly created scene as well (ex: new scene /w sphere)? Also, what version of Maya are you using? I was seeing the issue with Maya 2013.5 (EXT2).
Cheers,
Hi swakaj,
I originally experienced the issue on Maya 2013.5 and in Maya 2014 SP0. Just created a new scene with a Poly Sphere, went to the Render Settings and using the Presets menu, I performed a Load Presets > Default Settings for all of the renders (Software, Hardware, Mental Ray, etc.)
- On the Common tab, the image format is .IFF
- On the Mental Ray Quality tab, I set the Framebuffer Data Type to RGBA (Short) 4x16
I do not get the warning when rendering the scene using the PERSP camera. Changing the Framebuffer Data Type to RGBA (Half) 4x16 causes the warning to appear.
IIRC, Maya .IFF supports up to 16-bit and you would need to use a different image format for 32-bit (ex: OpenEXR). I suspect that RGBA (Half) 4x16 (aka RGBA_H) isn't supported in the Maya .IFF format. I can't be certain for sure, but I also believe the .TIF implementation is also max 16-bit ... maybe a seasoned Maya user can confirm this to be true.
Hope that helps,
Yes you are right, changing the framebuffer to Data Type to RGBA (Short) 4x16 solves the problem, Even if one selects any other framebuffer instead of framebuffer Data Type to RGBA (Half) 4x16.
Its just framebuffer Data Type to RGBA (Half) 4x16 that is creating the warning to appear.
I normally keep the file format to png insead of .IFF
No one seems to have pointed to the unsupportability of RGBA (Half) 4x16 (aka RGBA_H) isn't supported in the Maya .IFF format
Or now they want all to know and use more of OpenExr formats.
Anyways thanks.
Have a wonderful weekend.
Located this thread when I ran into the same issue all of the sudden in Maya 2014. Then to confirm the same issue popped up in 2015 as well. Please forgive my lack of phrasing properly as I am a student and new to 3d software as of 9 months ago.
However, I use Mental Ray, Raytracing, ambient occlussions, and even can make phy sun and sky work correctly. The two solutions for the issue I found is to change the light to a directional type. The other method is under your light attributes there is a special field for mental ray and it has a box for area light. Once selected you choose the shape from a drop down box beneath it.
This may not be ideal but your lights will appear in the render now. Of course Maya does have a share of quirks and it is good to export things out and make a fresh scene if the project gets too awry.
Most of this experience has been on my mac although it seems like a cross platform issue.
Hi,
I am having the same problem when I try to render with mental ray, but all the solutions above didn't work for me. I am using the latest version of Maya(2016), in a good workstation and I don't know what else can I do... I thank you in advance for the attention!

I did this and I no longer get the error message but my renders are black. Even with lights witout shadows. No such problem with maya software. The same file renders correctly in maya 2015.
Any suggestions would be very much appreciated.
I had the same problem with my MAYA 2016 version. All I did was, I installed 'DirectX'. Install the version which is compatible with your OS system. I am sure this will work.
