Terrain Exaggeration

Is there anyway to do terrain exaggeration with the Unreal Plugin? It would help see the topography more clearly in some things I am working on.

You could modify the scaling of the map (best done by attaching the Map Actor to an empty Actor and scaling the parent). This only works in a local scene.

Thanks for the response. I need a Global scene so that wouldn't work. Is there no way to intercept the height information and provide a simple scalar multiplier?

Unfortunately this is not currently supported, but we intend to add this functionality some time in the future.

In the mean time, you may be able to achieve something similar by finding the orientation of the up vector (with respect to the camera's current position on the globe) and scaling the map in that direction. But this hasn't been tested and the placement of other objects will likely be wrong (e.g., 3D object scene layers or actors using surface placement)
