Curious...on another forum, quite a few people have complained about vegas crashing while rendering a nested project. Quite the surprise to me as I have have done several complex nested renders without a single problem....
it crashes for me when i import a veg as media and teh veg is already hammering over 6 video tracks and over 12 audio tracks... with mp3... thats usually when it dies for me..
for smaller projects it usually handles itself ok...
It may be a memory issue. I think with Nesting Vegs, there is a lot more going on in the background. I have my PC optimized for background tasks (instead of programs) and my Dynamic RAM setting lately is mostly setting on 512 because I do so many RAM renders for editing. My Dynamic RAM setting is never between 0 and 128. Either 0 or 512 (I have 2GB of RAM).
