Title: strange render results...
Post by: wackymidget on August 20, 2008, 05:56:40 PM
Hi,

I'm getting strange render results. Can somebody please tell me what I'm doing wrong?

BTW I'm running Terragen2 on Mac OSX 10.4 on a macbook pro

What are you trying to do?

Hi,

I'm just trying to render a planet, but I get these black triangles at the sides...

Your render isn't finishing then.

If this is the unaltered default planet then I don't know. If you've added various shaders to the planet surface the try switching various shaders off until the problem goes away. I would hazard a very small displacement has got out of hand somewhere.
Good luck

I started a new project. Then zoomed out. I got the following result :(

The preview window also doesn't render very well once zoomed out...

Go into your camera tab, hit 'render camera' and check the 'horizontal FOV' values.

Your default fov should be '60'. I went in to mine, put an extra '0' in the box and I seem to have replicated your problem exactly in one move.

Maybe you accidently changed something there?

Look at my screenshot.

Ahh, I see what you are doing!

I rarely use the navigation panel, always numbers, so I didn't understand really how this could have happened accidentally.
To zoom, do it in increments of 5 from the render camera settings box or, if you have to use the navigation panel, set your zoom speed to the slowest speed by clicking on the first of the 5 speed bars at the bottom of the panel.

You have zoomed out to 180 degrees by using the nav' panel control. Nothing serious. Try just moving further away from what you're looking at instead of zooming out so much from a fixed camera position. Fov 60-80 degrees is usually fine for zooming out, 90-100 tops I'd say at 4:3 resolution, real stretching problems start to appear.

Thanks! I'm going to try this when I get home tonight.

Thanks everyone, not using the zoom solved my problem :)

Hi,

I'm getting some other strange render results... The rendered image looks nothing like the preview.
I included the camera settings and preview as well as one rendering with and one without atmosphere.

Can anybody please tell me what I'm doing wrong?

Thanks!

Found the problem. I set the motion blur to 0. This fixed the problem.
