I am trying to draw a textured sky sphere at an infinite distance. The model I am using is textured and has inward facing normals.

The example from the manual does not seem to work at all, the view seems frozen and the models texture covers everything
else.



I tried adding the SKY flag; "flags2 = SKY | SCENE | SHOW;". This does draw the model, but not at an infinite distance as it still suffers from clipping at clip_far.

I also tried using ent_createlayer() in various combinations with the same results.

Probaly it disappears by clip_far because it's a model.

Thats the problem! The SCENE flag is suppose to ignore the z-Buffer and draw the model behind everything else, so clip_far should not make any difference, but it does.

As the manual says, the SCENE flag draws an infinite z value into the z buffer. This has nothing to do with clip_far, which is the maximum distance of an object to be rendered. The SCENE flag does not affect clip_far.

For an object to become the sky, the SKY flag must be set. In your code above you have a view entity at an infinite z distance. The difference between a sky and a view entity is that the sky entity is rendered in the background, the view entity is rendered in the foreground of a view.

I hope this helps.

Thanks Jcl, I misunderstood the examples intent.
