Stephan,
Were you ever able to find a solution to your problem? Would be interested to see what you came up with.

Hi Dondi,

unfortunately no success. So we decided to create a non-interactive standard video.
Tools: AEFX + Navegar-plugin.
(won two gold awards :D s )

Hi,

as already pointed out, you need a special geometry for that with the correct UVs.

Also the mapping must match your fisheye effect as fisheye is a pretty general word - it mostly means catching an unusually high angle.

A special case is a hemisphere map, where you have an angle of 180°. That is easy to map. I've attached an example for that special case.

With your sample picture it won't look perfect. With a hemispherical map it does. You could fetch such an image from the web to try it in the attached scene. For instance this picture.

cheers,
rou
