I noticed them Brain, working on some cockpits as we speak, I have the outside fuselage/canopy mesh rendering without culling, so it must be this, I tried messing with these clipping settings to no avail. Only workable solution was to disable ShownFromCockpit entries in the aircraft I put my test work into.
With all the popular terrain/weather/treemods available is it so hard for TK to finally have a look at the alpha materials/z-buffer conflict?
(as usual NOT being negative, the workable code for fading is something I allways wanted, but I'm trying to move the gddamn rendering a bit further past few evenings without luck. Checking the TerObjectAlpha.fx shader line by line, experimenting, nothing so far)
