I am posting here a slightly modified help patch. And there are two problems:

– When I significantly change the camera position, the lookat point disappears from the window? In Max5, using, lookat point always stayed in the center of the screen…

– Try rotating the torus. The rotation seems totally buggy?

I am using MacBook Pro, Intel Core 2 Duo, 2.4 Ghz, NVIDIA GeForce 8600M GT graphic card and Mac Os X 10.6.5.

PS: In some other patch where I control lookat with some moving object coordinates, i can’t change rotatexyz values or they start changing automatically…?

it seems it is not a problem, rotation just don’t work properly in Max 6, or am i doing something terribly wrong?

check out the @locklook attribute of this will enable the old-style camera/lookat control of

the rotation problems are due to the fact that the values are converted from euler to quaternions and then back.
you will get less strange results modifying the rotatexyz or rotate attribute if instead of using the attrui, you use a pak object.
