Hi
I was testing out starfield in TGTP by using a starfield image and stick it on the background node. However, I decided that the stars were boring and I procured a much more advanced starfield image with different sized stars and shapes. But the image is inrecognizable when I apply it to the background. My initial though was that the image somehow got compresses to fit in the background sphere, so I increased the radius of the sphere, but to no avail. So, how can I use a more detailed image?
How are you creating your background? Are you using the Default Shader?
I am indeed using the default shader. I applied the image to the Colour image and Luminosity image (as stated in the starfield tutorial).
Did you turn the Luminosity to 10?
Yes, and diffuse to 1. But that is not the problem. Look at the attached image. It shows my original picture on the left and you can see how it turns out when rendered. The origianl picture is 1366x1035 if that is of any importance.
I've seen this. It has to do with either your settings (check all of them) in your Default Shader or how you've linked the Default Shader into where the Background Shader once was.
I know this works with as large as 1600X1200, since I've done it.
way it your quality at?

I am rendering with 0.4 quality.
I connected the Default Shader node into Surface Shader in the internal network of the Background node. All the default shader settings are equal to that of the starfield example.
you may want to try increacing your quality, when I do orbital shots I use at least 1.

Increasing the quality did not do any good. Also, I am not doing orbital render. The camera is at ground level.
hmm well, it it just this image? I had the same problum a while back with piture of a nebula im trying to remember how I fixed it.

No, not just this image. It seems that the problem is persistant with detailed images. Since I have no problem with getting a good result with a simple starfield image. If you are able to remember I would really appreciate it :)
could you post the image file so I could play around with it please?

thanks I get on it now.

Make sure your Opacity is set to 1, too.
Another thing, which looks exactly like what you've done - make sure on the Images tab that the Image Projection is Through camera.
Thank you calico! Setting the Image Projection to Through camera fixed it. Can you explain why this has to be?
Only explanation I can figure out is that the way you see the image in the preview window is how the background will be perceived. Not very technical, indeed. :P
when you use the projection camera, the picture is project like that on the world.

Here's my try at it. Just did a quick render with quality of 1.
Coooool.
