Shadows Effect creates an accurate shadow for any object. The object can be defined using a stencil bitmap from a matte layer. The shadow is cast from a point source.
You can download the Win or Mac trial version as well as a sample project to test it out. The watermark will be removed once you enter the activation code. The trial is full-featured except for the watermark.
This effect works with 8-bpc, 16-bpc, and 32-bpc color. The optimal usage will require 32-bpc and full resolution. In 32-bpc color, After Effects does not clip the video and allows the user to view any out-of-range data.
Shadows Effect Controls :-
Use Matte controls to isolate stencil bitmap.
Light – Selects the location of the point light source.
Types – Solid or Decay. The solid shadow is an accurate shadow cast with a penumbra. Decay shadow reduces with distance from the object.
Field Range – Clamps from 0-100% of the glow.
Accuracy – In case of stair stepping artifacts near the object, you may select a higher number. This number is the power of 2 that we use to multiple 360 degrees to generate sub-degree level accuracy when casting a shadow.
Penumbra Factor – This number controls the thickness of the penumbra.
Penumbra Degrees – This is the value in degrees that the penumbra is calculated. TIP:- Use larger value here if you find penumbra is being cut off.
Opacity – Amount of glow to blend with the lower layer.
Tint – Color of shadow. If you change this to any other color, it functions as a custom spotlight.
