I managed to work around this and I was able to do it with the shadow…but now I had to do many tweaks, somehow start from scratch…and I have this ‘water drop’ that has to come out of a surface.
I got the camera tracked in AE:

Then I created the water drop….and done the movement in C4D. I put a “plane” to recreate the surface in the video.
but the “plane” should NOT be visible….instead I would like only to get the reflections on the place. I’ve done the workaround described before:


But the “plane” is still visible 🙁
Would anyone be so kind to give me a heads up on this to get this done? Any help would be HIGHLY appreciated!!
