Hello, I was able to put texture on TextureCubeMap, using the code by Jean-Sebastien. Thank you very much, again.
Now, when I try to use a 2048x2048 jpeg image for the texture, I get this message (after viewer.run()): Scaling image 'skybox-1.jpg' from (2048,2048) to (512,512) And indeed the image seems rescaled to 512x512. It does not have the quality of 2048x2048 image. Is there a way to use the 2048x2048 image without rescaing? What component is enforcing this 512x512 restriction? Any help shall be appreciated, Thank you. - Nao On Thu, Aug 28, 2008 at 11:42 AM, Naomaru Itoi <[EMAIL PROTECTED]> wrote: > Dear Jean-Sebastien, > > Your advice worked perfectly.
