Mylenium - Either you or I are missing the point.
No, actually not. We are both right and both helpless in changing the matter. ;-) You are both not considering, that AE's internal measure is pixels. It has no such thing as an abstract "world unit" as one can setup in 3D programs. Therefore, any physics are based either on absolute pixels or percentages of those pixels, at best quantized to the sub-pixel precision grid and that is dependent on the comp resolution/ size. For "predictable" behavior independent of the resolution, you would basically have to treat everything as a procedural 3D item, so the sampling is based on testing the 3D intersection, e.g. with a procedurally defined ramp "texture".... It's really more complex than it looks on first sight, so for the time being, we will probably have to live with these limitations.
