Title: How to let clouds interact with objects?
Post by: zzu on October 27, 2016, 10:53:44 PM
Like the one in the paramount 100 anniversary intro, when the stars fly by, it kinda disturbed the clouds. Thank you for the reply.

This foreground clouds have been done with Maya I guess. You cannot have this kind of interactive effect in Terragen atm!

oh, I see. Maya's fluids' very slow, but yea, it's doable.

but in Terragen, clouds do react to geometry like mountains though?

You can have clouds interact with terrain, but not object geometry. You would use the Altitude Offset and/or Depth Modulator for this.

The lower-level clouds in the Paramount intro are I believe Maya clouds.

Thank you two. It's interesting, I'm thinking is there a way to trick terragen into thinking that an object is terrain?

In principle, I think, very perhaps (never done it) it should be possible to locate a camera at an object, attach a distance shader to keep any effect close to the object, and use the fractals on that object (terrain or any fractal) to warp the clouds around it. Very perhaps  :-\

Not currently, no.

Imagine animal-shaped clouds, planets surrounded by concentric rings of fluff, the gods playing chess with cloud pieces...
I've already thought of how to do the second one there, but the others...   8)
