Alright, one of the most important 158th models, a great floating station in the sky, is having some severe issues.
The station features 2 fly-in hangars, large grand hangars that have about 20-25 meters worth of height. 4 landing strips are textured onto the top. Clipping issues seem to have floor polys from the top hangar clipping through the landing strips on the very top. A similar case with the main hangar has polys from the lower hangar clipping through its flooring. Finally, the lower hangar has polys from the hab module (the model is divided into 3 modules with the hangars in the top and hab below them) clipping through it's flooring.
I've run into this before with other fly-in hangars, but those were all largely unstable models to begin with and were more gineau pigs for my experiments in TS than anything else. This model as far as I can tell is stable and solid.
The second issue has to do with the sun shining bright and clear, straight through the wall of the hangar. The polys are in place, the sun just shines right through.
Input is greatly appreciated, as are suggestions on how to fix these things. I'll have screenshots of the clipping up tomorrow afternoon, but until then, all I have for you is the beautiful picture of the sun disregarding the bounds of the hangar wall.
