Hy guys !
I have this weird error I'm getting all the time in maya after I zoom out too much ...

Why is this happening ! If I had a bigger project I could never be able to see it from above !
What should I do to fix it ?

The screenshot is composed out of part 1 which is one zoom away from part 2 (both were perspective camera only made one img with photoshop)
Any idea why that is happening ?

Thanks so much !!!
Best regards, Vick.
