I rendered out the silhouette of the arch, put it as an opacity map onto a sphere, and no matter what I did, I got a strange shadow gap even where there was shadow without the plane.So I used this shadow map and created a spline object out of that in Max, converted it into a mesh and used this one as shadow object. I hope this is OK with the rules as well, since I'm rendering something quite similar to the previous invisible card in TG.

But I will of course follow the rules. So, if there's any concern, I'll think about something else.
