Hi everyone ! 

I tried for already 4 days to fix an issue by reading different forums. Any of them help me out.
So I decided to finally post my problem here with the hope that somebody will get me out of this problem. 

So, each time I tried to render with MR it crash after a few frame then when I restart maya, and do the render again it crash right away.

I already tried : 

- Delete History
- freeze selection
- Delete unused node
- Render the current frame ( unchecked auto memory limit ) calculate : 24.8gb
- Export import in a new scene
- cleanup
- change the bsp to Large bsp
- uninstall and reinstall Maya 
- delete all shader and render
- I even reinstalled my window completely
- Render Globals / contours, disable hide source, lower oversample and filter support to 1
- deleted all of the scripts
- reload Mental ray 
- I also tried to render with mayasoftware 
- I tried Maya 2013 
- I tried a new scene also with only a cube and Mental ray 

And the final, I tried to render with my old alienware guess what ... 
Everything render properly --_-- 

When I render this is the error : 

// Warning: (Mayatomr.Scene) : output data type "rgba_h" not directly supported by image format iff, conversion performed by mental ray // 
// Error: *Fatal* (mental ray) : mental ray encountered a fatal error. The system may have become unstable. Please save the scene and exit Maya. //

when I start the render diagnostic : 

- This scene contains nodes with animated visibility, this requires Optimize Non-animated Display Visibility to be turned off.
- Node persp has animated visibility.
// Warning: file: F:/Softwares/Autodesk 2014/Mental_ray_maya/scripts/mentalrayDiagnostic.mel line 524: 1 warnings, see script editor for details. // 

in the output window the two last lines :

RCFG 0.8 245 MB warn 542009: finalgather ray returned NaN for the finalgather point at pixel 844.586 620.252
PHEN 0.3 316 MB fatal 051109: runtime exception 0xc00000fd: stack overflow

My computer spec : I7 3930k / 32gb ddr3 2166 / geforce 780 / window 7 pro 64bit.

I hope you guys can help me !
Thank you

So this is something wrong in your computer.


Could you try to rename or delete maya user setting folder?

XP: C:\Documents and Settings\"user name"\My Documents\maya\"version"

windows7: C:\Users\"user name"\Documents\maya\"version"

Then when you lunch maya, select "create default preferences".


If it don't work, try this.

1 create a new windows user

2 log in as new user

3 lunch maya select "create default preferences" 


If it don't work too.

Reinstall Maya and try again.


If all of this can't solve your problem, you can check your computer's hardware.
