Title: Misshaped Planet
Post by: Markal on February 06, 2010, 11:06:51 PM
I'm working on a space scene...I set the Render Camera, perspective, Use horizontal FOV at 75....this streaches the view of the terrain horizontally a bit. I also rotated the terrain view to 23.  The quick render camera aspect ratio is 1.5 with the pixel aspect ratio at 1.
   The planet object is quite obviously egg shaped and not round....is it possible to get a round planet with these streached perspectives and ratios?
Any tips/suggestions would be appreciated.....I like the look of the angles, perspective and aspect ratios on the terrain and really would prefer to keep them and somehow adjust only the planet object to make it round and more natural looking....help!!!

Try to scale the planet object in the negative axis (I'm assuming Y) so it will round it out. Just a thought.

I would like to scale a planet to stretch it in a particular direction also, how do you go about doing this?

Another way is to limit the focal length (?) to 50 and move the camera. 50 seems to help with very wide renders where vertical objects start to bend oddly.

Comp in post .
Beside this i don't know a way to do this with this wide FOV .

The FoV-related distortions are part of the camera effect. Orthographic camera should avoid this, but it has other issues, depending on what you're trying to do. Moving the camera further away from your scene might be better.

You cannot currently scale planets independently on each axis - they are sized by radius.

You know you could in future get round these distortions if Terragen had a shift lens for its camera, this feature is found in other rendering engines Maxwell Render been a notable example though there are others: another use would be to compensate for the phenomena of Converging verticals, and to some degree lens parallax.
