Mental Ray Rendering Fatal Error

Maya
1

hi and thanks for Any help .
i am rendering a Helli that is pretty detailed and when i render i get this thing

// Error: Fatal (mental ray) : mental ray encountered a fatal error. The system may have become unstable. Please save the scene and exit Maya.

and i checked every thing i know with in maya .
its maya 2009 and i can render sometimes until its crashes i checked any duplicated node with the same name and i have no idea how to solve it and i want to continue with the project.
so pleas help and thanks a lot.

Can you render one frame? If so then its pribably not worth debugging but rather just launch the render form command line in loop that restarts mentalray every so and so frames. Its most likely a very close call with memory max.

What os? winXp32?

well if i take a bline and replace from all of my materials (thetas are blin to but with textures file)
the minuets it a nor mall blin i have no problems to rend it as i wish.
i tough i found the node who is responsible but igess i didn't .
is this problem sound furmiler?

Well large non-bot (bot is mental rays own pyramidal texture format) textures can eat a LOT of memory an most users dont really have all that much memory at their disposal, because of small catch in 32 bit systems. So 1.5 Gb is eaten up very quickly. I mean its not uncommon for me to blast up to 6 GB of memory when rendering simple tests. My record so far is a render that ate 15 Gb memory whan cleaned up.

64 bit OS is starting to be minimum requirement for anything theese days. Unfortunately that doesn't count mac.

ok thanks a lot but is there any way i can render the texture file on a 32 bit machine?
and raelly thank you for evry thing

Convert the formats to bot that way mr can eat them form disk. There's a command line utility that ships with maya to do this or get one of the few make bot scipts on this site.

Run render form command line that will save you a few hundred megs of memory and then enable the 3GB switch in the boot.ini
