    1 - How can I create mist or fog?

    Contributed by B@rt.

    Mist is a function of the World Buttons window (the Globe button). First add a new world by clicking on the '-' button in the window header. Next, select mist and change the settings:

    * Qua/Lin/Sqr - Quadratic/Linear/Square root falloff.
    * Sta: start distance, measured from the camera
    * Dist: 'thickness' of the fog, measures from the start distance.
    * Hi: no idea :)

    To show the Sta and Dist values, select the camera and switch to the Edit Buttons Window (F9). Select 'Show Mist'.

    2 - How do I create a starfield?

    Contributed by Daniel Jircik.

    Click on the World button, click on stars. To create a denser field adjust the distance number. Note the denser the starfield (as in particle) the slower the render time. To create multi-colored stars increase the value in the Colnoise option.

    3 - How do I create a realistic sky?

    Contributed by Daniel Jircik.

    This is another topic of which a book could be written, but try this.

    1) Obtain a generic jpg of a sky/cloud patern. then in Gimp create a new image with twice the pixel with of the original. IE: 2:1 (X:Y) copy and paste the original image onto your new one. Then in Transforms select flip so that the end of the old image meets the identical start of the new image. Selecting a good cloud image is important as you want to have a semless joint.

    2) Assuming you have created the scene which you need the clouds for make a tube that encircles your image. Try to keep the surface aspect ratio roughtly 2:1 but with clouds sometimes a little squeezing is desirable. Use your new panoramic image as the texture and voila. Alternately you can texture map onto a squashed sphere.
    Have fun. Don't forget to eat.

    4 - How can I add a background image to my renderings?

    Contributed by B@rt.

    To load a background image for rendering, do the following steps:

    - Switch to the Display Buttons screen (F10)

    - At the line saying 'Backbuf', press the one of the two small buttons at the beginning of the line. The first button will show previews of images; the second image only the filenames (this is much faster for directories with many images in them).

    - Select 'Backbuf'
