I want to make a world inside a skybox, but this skybox must include object like enormous starships or other giant buildings too far but not
dead.

The idea is to create a camera that point to this "skyworld" and visualize it backdropped, behind the world. When i move, my camera moves normally, and the sky camera moves very slowly, and i have the sensation of a skybox.

It is possible on dppro to have a camera backdropped on the screen ?

(i think that games like painkiller use this method, but i'm not sure).

i think i know what you're saying. you could have this "skyworld" away from the player's world and you could have a camera trained on it and move the camera as the player moves. then by using the SET CAMERA TO IMAGE command you can grab what appears on the camera and set it onto your skybox. not quite the effect you wanted but it would work.

oh, and if nothing ever changes in this "skyworld" then why not just make it a texture?

Yes it is.

Firstly, you need to ensure that your skybox is the first object that you create within your game, and then you can use the DISABLE OBJECT ZWRITE to stop it updating the z-buffer.

Note - it is the order of creation and *not* the object number that determines the correct draw order. The earlier you create an object, the earlier it is rendered in the draw sequence.

Here is a very basic example - I don't have time for much more at the moment.



Object 1 is the skysphere, object 2 is an object inside the sphere and object 3 is an object outside the sphere.

You can move the MAKE OBJECT SPHERE around within that section to see what happens to the other objects (ie, try making that command the last of the three and see what happens)

I tried for now to grab an image from a separate camera, but it does'nt work : it returns me an error : cannot grab image due to an illegal area (error 504). What this means ???????

It's not a DBPro bug - it's your code. Remove that MAKE CAMERA command you added.

Ok, i understanded the working way of the cameras. i found a solution to change cameras. But the problem of the illegal area (written 3 posts ago) remains. What is this ???

Dunno, but show a small example and I'm sure we'll be able to work it out
