How could I find out which parts of a Landscape are rendered?

[werner.poetzelberger]

For planning I need to find out which parts of a Landscape are actually seen and rendered by the camera.

Is there a - NEAT - method to mark the seen/unseen parts of a Lanscape in a mask e.g. or pained in the Albedo.

Doesnt need to be in realtime (I mean every frame).... but need that info - visually would be enough.

Hi Werner,

I only can think of a fully custom solution that will calculate camera frustum and somehow project it to the mask (like if you will look on terrain from the bird's eye view).

Not sure it this would be the best, but I think you could do these:

• For a one-time design solution, you could just position the editor camera at your game camera position, and just paint the albedo with the landscape editor tools
• For a real-time solution, but maybe too slow, a perspective decal placed at the camera position with the same FOV could do the trick

Haven't tested any of these, but the solution could be of some help to us too :)
