View Full Version : Move Across Polygon Surface.

10 October 2005, 10:05 PM
Attached is a file i found where an object can freely be moved across a polygon surface. I need this same effect for some work i'm doing. However when i replace the "plane" object with different plane object that is rotated vertically the "sphere" object only moves half way across the "plane" object.

Got that? :)

Thanks to the author of this file, whoever that is.

This was because there were no offsets from the Sphere Z position for the Ray Points. I've added nulls for the Ray Points and a Hit Position null to convert the global Z offset for the Sphere to local.

Setting it up this way makes the setup portable under a master null. The expression will keep working correctly when the master null is moved or rotated.
