Cannot move light behind 3D object in AE without everything turning black

[deltabox]

So I've been trying to move my parallel light behind this 3D object in AE, so the shadows will be casted towards the camera, but whenever I move it behind the whole environment turns black. I imported the 3d object with Element 3D and I tried to rotate it in all orientations but the shadows are still casted away from the camera.

The Element 3D is a layer indeed, but moving the light behind the 3d object without everything turning black only works in Draft 3D mode, which I think is quite weird.

I've tried to search all over the web for a way to make it work properly, but I cannot find any topics about it, so I decided to bring it up myself.

Here's a gif that explains my problem:

Here's a gif where I do the same as the above but with Draft 3D enabled:

I really want to be able to cast the shadows towards the camera so it looks like the lights comes from outside the window at the statues.

That's a limitation of how stencil-based shadows are calculated. You would have to use raytrace shadows, if at all, or switch to a spot light.

Raytrace shadows gives me the same results I'll try with spot light instead though.

You need to add some ambient light. Try setting the value to about 40% and see what you get. With ambient light:

Ambient light seems to be the fix for this! Works best especially with raytrace shadows, thanks for the help.
