This post is mainly to reduce headaches related to this strange issue. I’ve been having this trouble for a while, but just recently found out what it was.
If you have a scene from the olden days (maya 2009 or so) you may have imported stuff into a later version of maya, in my case 2012.
If you’ve done this, and randomly and inexplicably found maya crashing at certain points in the render, or when the hypershade is open at certain times, you may have luminance nodes in your scene plugged into a bump node… like I did. I’m staying away from luminance nodes all together for now, but they may very well be safe in other applications.
You’re probably annoyed with it, and want to know how to fix it. Well, there is actually a very easy fix. Just replace the luminance node with a rgb->hsv + ramp remap setup. If you cant even open your scene because it crashes upon load, try this.
1) Close maya
2) open maya
3) open script editor and run this mel script:
“renderThumbnailUpdate 0;” with out quotes of course
4) open your scene file, strip out the luminance nodes and replace with whatever.
5) save scene if you want
6) run “renderThumbnailUpdate 1;”
“renderThumbnailUpdate 0;” tells the shader balls to not update when you see them, keeping you from crashing when that particular shaderball is visible in the hypershade. just remember to re enable it or you’ll have a hard time seeing your tweaks update. These make great shelf actions btw. I’ll probably make this into a script and post it up here later. If you would find this useful too, let me know and I’ll probably be more likely to write it.
