I think I overworry about it, but they do happen. Maya seems to destabalize sometimes, so like, last night, I introduced a new texture map into the scene, and Maya crashed. But I know from experience that if that happens, I turn off, turn on again, and chances are it will work. But there will come a point where it wont take any more. At the moment, I have 2 2048 maps and 1 4096. One of the 2048 ones is duplicated in some spec and reflection slots. Render times are about 3 and a half minutes at the moment, which goes up to over 8 when I add the landing lights in there.
