Our entire office is having this unpredictable and infuriating issue. Here are the bullet points of what we know/have experienced:
-We are using Mental Ray for rendering, so we're using Arch&Design materials, but it also happens with Standard materials
-We are in the process of upgrading to Redshift and it also happens with Redshift materials
-It happens to materials with "show shaded material in viewport" checked
-It happens to materials with "show realistic material in viewport" checked
-It happens to materials with neither checked
-It happens to materials that use texture maps
-It happens to materials that don't use texture maps
-Scene size doesn't affect it; it can be very small and basic, or rather huge
-Distance from origin doesn't affect it
-It started when we upgraded to 2017. Prior to upgrading, we were using 2015.
-Upon opening Max, we have to switch around and find a view setting that happens to work best for us at that particular time. Flat vs default vs facet in conjunction with standard vs dx mode vs high quality (though high quality is almost always too slow to use even if everything is visible; our scenes can get pretty large sometimes)
-----what I mean by this is, with the same exact scene, Standard+flat may work the best; open that same scene a different day or later the same day, and all of a sudden Standard+facet works the best (making invisible things visible, that were previously visible with Flat earlier that day). Sometimes, nothing works very good and you have to close and re-open Max several times until it randomly works (I've restarted up to 6 times before)
-The same thing is happening to all users on multiple types of machines. I am currently using a laptop with i7-6820HQ @2.7 GHz, 16 GB RAM, and Quadro P3000 (I'd like to point out that this is pretty much the beefiest laptop video card there is...). Other machines are also running very high end processors with 16 GB RAM, but video cards include Quadro K5000 and Quadro M3000M.
-Everyone uses Windows 7
-Sometimes selecting the invisible object will make it show up, but it will disappear again shortly after deselecting it. Sometimes it disappears instantaneously, sometimes it fades away.
-Sometimes selecting the invisible object will have no effect whatsoever
-It happens with adaptive degradation toggled
-It happens with adaptive degradation not toggled
-Shadows on, shadows off, use default lighting, use scene lighting, no affect with any combo
I was going to start my own thread with this issue since, like you said, it may be a different issue than the OP, but you asked @Alfred.DeFlaminis! So here it is!
