[Solved] Sky model has no bottom

[nerdcafe]

Same problem as this guy: Sky Model
I use alpha tiles to make the sky visible but in the middle is this huge black hole. It looks ugly.

I tried to use sky picture as doodad but it disappears when the doodad is not on camera.

You will need to make your own skybox model with a floor. There was no reason for Blizzard to texture a floor for the model seeing how terrain would always obstruct it.

This is assuming it is not some strange hidden back mesh from the terrain obscuring it.

Do you have any idea why when doodad is not on camera it disappears? I already set visibility radius to maximum.

Try recalculating its extents in Warcraft 3 Model Editor and reimporting it, usually it fixes disappearing custom doodads.

Thanks it works.

To save on draw calls. Draw calls are expensive so Warcraft III only draws what is sensibly visible. StarCraft II does the same.

With camera projection hacks you can see that Warcraft III does not draw terrain patches, units and doodads/destructable that are too far off camera.

If something is visible and needs to be drawn is determined by its model extents.
