The Per-Object shadows of a large object that I have on my level appear just fine, but as soon as it starts moving via Matinee, the shadows disappear. This was not happening in UE4 4.1 (seems to have broken in 4.2?). Or maybe I have to activate a flag or something?
Important additional info: The Matinee has one mesh that is being moved, but in the level I have a dozen of other ones that are attached to the original so that they all move as one large unit. The shadows for the original object and those being attached are all visible in the editor and disappear as soon as I simulate/play.
It sounds like the bounds are getting messed up somehow, that would cause the shadow to disappear. You can visualize those with ‘show bounds’ in game. Do you have any special flags set like bUseAttachParentBound? Otherwise might be a bug.
I checked in-game using ‘show bounds’ and it seemed to be ok. I’m using the ‘Light Attachments as Group’ option in lighting… though I’m not sure what effect this has.
In any case this definitely “broke” when updating from 4.1 to 4.2. My main light is a stationary light.
I just tested disabling the ‘Light Attachments as Group’ and it got fixed (I thought I had tried that before, but apparently I didn’t. Now I’m ok. Thanks for the support!
