[Question] Objects disappear at certain angle.

[Klein~]

Hey!

So, I have this little problem - I add objects to my edit, I move them around and such until I'm happy with its positioning and I make an MPQ.

Right, so I go ingame, everything Is there, I'm happy but.. SOME objects like trees, fog, roots or such disappear at a certain angle. When I look at It directly, It's clearly there.
When I try to eye It partly from the corners of my screen, they disappear. It's really starting to bug me.

Also..no! I haven't oversized them.
Any help will be appreciated! =)

Problem may be that some MCRF entries are not properly set. Noggit has issues with that. Also, when using custom models, the header stores information on the model boundaries. If these are set to wrong values, WoW stops rendering them too early in some cases.

Thanks for the quick reply schlumpf. And thanks for offering some problems my issues may be caused by.
Could you perhaps tell me how I could attempt to resolve my dilemma exactly?
