Hi all.
I have built a scene which has a cliff. The cliff is made from a simple mask attached to a surface layer. The surface layer smoothes and then displaces the area by an offset of 2500. No multiplier.
Then I compute terrain then base colour node and three surface layers providing only surface colour changes. No displacements. Then a surface layer with fake stones as a child.
All looks lovely, so I start to animate my camera. Position 1 is at the top of the cliff, a cliff which is 2500m high (ish.) I move my camera back a couple hundred m
and I am still right on the edge of my cliff. WEIRD! I know scale can be deceptive in Terragen but I thought if my cliff was the right height my fake stones on the top of my cliff all look correct all was good. So I got the ruler and measured a fake stone. 12m.
And I realise what look like small bumps at the top of my cliff are in fact mountains!
One thing I left out and I guess this is probably the key. Around my cliff is a mountain range. This is derived from a power fractal with a (feature scale of 5000)
a (lead in of 6257.06) (smallest scale .13) (Octaves 18) and a displacement of 2000. In my cliff surface layer I have reduced the smoothing to allow some of this
displacement to come through. Is that what is throwing the perception of scale off?
Thanks.
James.
