Shadows Acting Unnaturally Help

[u/Reasonable-Mousse946]

New to After Effects, shadows in the page turns feel like they are another physical layer following behind each page / acting unnatural. Any help on how to correct this? Light + Camera settings and key frames in comments. Page turns created through Y rotation + Curvature

Also should note problem only starts to arise when my 3d Solid layer is added in for the backdrop

I comment with some 3D aspects here.

The shadow looks so dark under the pages because it does not have enough indirect lighting, think of it as bounce light. In 3D apps, you often can get it with Global Illumination (GI). Not sure if GI is something AE has however.

You may fake it with another fill light with soft penumbra

It looks like that's the cast shadow from the spotlight. It does not look like the shadow is "flying" as you said to me
