Shadow Errors

Hi everyone,

I've been doing some look development lately, and noticed a problem in my shadow pass. On any rounded surface (i.e. spheres, cylinders, complex shapes), a harsh line gets rendered on the object where the light begins to fall off. This is causing issues with regard to compositing. Please see my attached examples, and download the scene file for yourself. I've tested this with both R13 and R14 and am seeing the problem in both versions. I've also seen this happen with both Area and Shadow Maps, but my example file is using Area shadows.

Any help you could give would be greatly appreciated.

Thank you so much!

Have you ticked shadow correction in the multipass settings?

Have you tried to render shadow channels with Open EXR file ?
It could work better with compositing your shadows.
