Texture corruption

[Boux]

Hi, there,
There is texture corruption on a backgroung model when the observer gets closer to a foreground model (when entering the collision box?)

Screenshot from a distance:


Getting closer (textures flicker badly on the space station model)

Boux,

It would help if you could circle the regions which are damaged, showing which is correct and which is not.

For someone unfamiliar with a model, it's hard to tell what is intentional and what is accidental.

It's another depth sorting issue. The near plane is probably getting set to close, resulting in flickering from z precision issues in parts of the model further from the camera. Do you have a link to this add-on?

The background add-on is the Deepspace9 station from Jestr's Star Trek universe (Motherlode).
The foreground model is a conversion for Celestia I am working on from a model by Rick "Hobbes" Snider from scifi-meshes.com.

It would help if you could circle the regions which are damaged, showing which is correct and which is not.

If you look carefully at the space station model, you will see many areas where textures are corrupted (they flicker when in Celestia).

What are the radii of the two models?

DeepSpace9 --> 30 km
Kerchan ship--> 500 m
Hubble --> 7 m (just made a test with it)

Here is a shot with Hubble put into orbit over there.
Same texture corruption on the space station when getting closer to Hubble:

Look at black triangles here and there (clearly visible on the spoke on the left) and wrongly rendered "windows" on the station (should be white-bumped dots).

EDIT
Ah here is the ssc if it can help
