Hi!

How do I import height maps into the world editor?

Currently this option is not available - you should sculp the terrain in the World Editor instead.
The feature will be added in the future.

Thanks for the quick reply

But is there anyway to make the hight map bigger than what you can make in the world editor?

Bigger? What do you mean by that?

You can place two heightmaps or more of course (just keep on pressing Insert key in the world)

What I meant is that you could only insert a rather limited amount of height maps.

But it seems that it has been fixed now

This is not Correct, if you are sculpting in the World Editor you can Zoom-out via WSAD and the editing Block moves away.

Personally I prefer to use 4th/5th mouse buttons to move/rotate the camera (or their keyboard equivalents - Space / Windows key)
