3D light casting shadows causes morays or vertical lines

When I rotate a layer in 3D space with a point light casting shadows on it, it creates a vertical line pattern. If I use a spotlight, it creates a moray pattern. When I use ambient, it goes away, but so do the cast shadows. How can I fix this. I am looking at the composition at 100% and I am using square pixels. I have set the bit depth to 32.

Which version of AE? If you're on CS6 or CC then try to use the Ray-tracer render to see if this fixes the problem. Another solution is to move the light source away from the layer that is emitting the shadow - move it until the artefacting goes away.

I found that the Ray-Traced works better than Classic 3D (under the Composition menu, Advanced tab). Another solution that I also found was viewing my composition on "Full", instead of "Half". This got rid of those either horizontal or diagonal lines that kept appearing wherever there were shadows.
