Odd Shadow

[eon_designs]

Hello

We have recently upgraded our keyshot 3 to version 4 (the latest one 4.0.74)

When rendering this image (just shown part of it) where there is supposed to be a very slight shadow I am getting something very odd happening. This has happened a few times on different renders, always where there is a shadow.

Thankfully this was originally created in Keyshot 3 so I was able to re-render it and got a perfect background, but if you open it in Keyshot 4 and render this happenes? There is no evidence of this in the live view - only when you perform a full render.

Any suggestions? is it a bug or something realy simple that I need to change.

This happens when DOF is on or off, sample setting is around 32, all other settings were 2

Thanks. eon

A similar thing happened on another render - here it is in the reflection - same sort of patch work?

Very strange.

Any suggestions. Thanks. eon
