Unusual Viewport Issue So, I'm not sure what's going on here. But I just finished an animation in another file and came to this model I'm working on and... well I don't know how to explain it but any time I get close to the object or camera, it begins to disappear. I'd rather not factory reset as I have a lot of custom things set up. Any idea's what causes this? I use Shift+f to move around, scroll to zoom in and out etc... Blender 2.79b (still need to get used to 2.8 I have used blender a lot but still a noob)
The cause is almost definitely your clip distance. You can make the objects you are looking at bigger or change the clip distance by pressing N in the viewport and changing 'Clip Start' to a smaller value.
