Hello,
as far as I recall, in earlier blender versions, you could see the background grid through your mesh. aswell as any camera/lights.
I found, that in 2.7 I can no longer see the grid. and editor objects (like empties, cameras, lights etc) can be hidden behind any mesh. I looked through any property windows + user preferences for 15min now, but can’t find anything. google is also no help and here is no topic on that as far as I could see.
Did anybody else notice this? And if yes, did you fix it?
Here is an example:
I don’t think there ever was a version that had default “transparent” meshes…
But if you do want it, make the things you want to see (like editor objects) “Xray”.
you’re might be referring to pre-2.5 (and maybe early 2.5+) when the “occlude background geometry” setting was off by default. you can turn it off by pressing this button:
