TXMP links

According to the swapcode table, the 20 links are in fact 4 groups:

• 6 (skybox, bottom one is never used)
• 8 (only first one is ever used (sun))
• 1 (never used)
• 5 (first one always lensflare02, other 4 never used)

Issues with the sun

After upscaling and positioning the sun, two bugs remain:

• the sun texture is rotated 90° counter-clockwise
• the sun isn't occluded by anything at all :(

Planets

Multiple planets work, but the occlusion issue is still there.

Stars

Stars are not placed the way plantes are.

They are probably generated at random...

Original ONSK

• afternoon (level 1)
• sunset (level 2 and 3)
• crapsky (level 19)
• night (all the other levels except level 13, which has no ONSK)

All ONSK are identical apart from the sun stuff (see above) and the skybox textures.
