FP 3.41, MAX2010_64, XP x64
I am having a strange problem that I can't recall seeing before. I have a scene where there are about 500 trees and they are mostly spaced apart such that when you look in an area, you can see the whole single tree standing alone. The next tree is standing alone further away from the first tree, etc. So you can see each tree individually.
The animation is a camera following an aircraft and down on the ground below are the trees.
The problem is... as the finished animation is played back, the scale of the trees changes on different frames. So for example, the tree might be fine on frame 1, 2, 3, 4 but on frame 5... the tree gets wider. Then on frame 6 the tree goes back to the original size again. Then maybe on frame 17, 18, 19 the tree gets wider again but on frame 20 the tree returns to normal size. The result is the trees don't stay a constant size.
As I step through the animation in MAX, I don't see the trees changing at all.
The trees were placed by using the Tree Editor to place trees at the locations of point helpers (not sure if this makes any difference).
Have you ever seen this type of problem before?
