I'm trying to put together a video which uses 3D objects of an iMac, a phone and a tablet that I've found from various online stores. I'm brand new to working with 3D objects but the questions I have are:
1) What is the best way for me to put screenshots on the screens of these devices? I don't see a way to do it via the properties for the 3D objects, so I've been importing screenshots as a separate 3D layer, positioning them "on top of" the screens of the 3D objects, then parenting the images to the 3D objects. It feels like there is a better way to do it, but I don't know what that is.
2) Sometimes I am seeing glitches when I render scenes where I've animated the objects moving and/or the camera moving. For example, when the camera pulls back, the iMac's pedestal disappears and surface "tears". I even see the pedestal disappearing on the 3D object when in perspective view as I scrub my way through the timeline. The problem goes away if I make the objects '3D plane' instead of '3D unrolled' but I have been adding them as '3D unrolled' layers as this makes placing them in 3D space using the perspective / top / left view possible. Am I doing this wrong?
