I've spent hours trying to track this down.
For some reason, the shadows cast by this piece of clothing disappear at close range (see video).
If the distance is increased between the avatar and the clothing, the shadow reappears.

What I know:
* It's not an ambient occlusion issue that I know of. I checked by turning off IBL and using only spotlights.
* It shows up while previewing AND after rendering out in iClone's Native renderer.
* It doesn't show the problem after rendering with Iray.
* I get the same results in both CC3 and iClone7.
* Unsurprisingly, the same result occurs is you "resize" the garment. (But it's already on the *large* size, so that wouldn't be a work around).

It's possibly something simple, but it's sure got me stumped.

@4U2ges - brilliant! - you nailed it!
It was playing up while set at -5.
Dialing it down to -1 totally solved the issue.
Thank you so much!  :)
