Objects are invisible at certain orientations, only when viewed through an orthographic camera

Hi, I’m trying to make an application that allows user to rotate a model with arrow keys. application worked fine until I switched my in game camera to being an orthographic camera, now at some orientations model disappears from view completely. I’m doing rotations using blueprints, and I’ve watched values in blueprint and nothing funny happens to them. Here’s what it looks like when its bugged, with my object not showing up:

Here’s what its supposed to look like when I set object to a different rotation with my key inputs:

It seems like at only a few orientations it bugs out, if I randomly spin it around it only bugs out and disappears maybe 5% of time.

Hi janimationd,

I made a project with this same setup, but I was not able to reproduce this with orthographic camera. only thing I can think is that maybe your camera is in a position relative to rotating actor such that actor is no longer in view, though that seems unlikely if it only occurs sometimes.

Can you upload project somewhere like Google Drive or Dropbox so I can take a look? You can send me a download link privately if you need to via PM on forums:

Thanks!

Hi ,
I can no longer replicate issue, it’s likely because I switched away form mobile version of UE4 Mannequin in favor of normal model. My camera wasn’t near model, and it only happened at really odd angles. I don’t think posting my project will help since issue no longer exists. We can mark this resolved since its no longer an issue for me, but I’m guessing mobile version of UE4 mannequin was causing issues.

Glad to hear it’s not a problem anymore! I’m still not able to reproduce this, even when using mobile mannequin, so if issue comes up again please reopen this post and we’ll keep looking into it. Thanks!
