Irrlicht Engine

Well i've searched the forums related to this and i have found nothing so if anyone could enlighten me?

Im sure its an easy fix but i've searched and found nothing
where i get to far away from my map it disappears
like this:


How would i fix this?

K. So i got it but now the box is to small i dont need the plane in GTK anymore but this is what i get

i made the model with GTKRadiant

and want the grate to be transparent i have tried the code posted by bitplane
and it still dosnt work =\

haha fair enough WELL

the grate you see right. it should be alpha but instead its created a spirte in the background that is alpha of the same texture and i got no idea why.

So i've just started using the irrlicht engine i have managed to get get alpha channels working BUT i have run into a problem.

its not on the plane that i want it to be instead it creates a whole new sprite at the camera node start point
