I wasn't sure where to post this, but maybe it could be a fix for both pop ups and rotating objs? I have layered alpha glass pop ups on my EMPERORS SUNRISE mod that seem to work fine, but I created a swing out windscreen for my FLATTY MODEL 8, and it works as intended besides this strange bug with the windscreen alpha. Same alpha I had before I broke it off as a pop up light subob.
I've seen this bug before, like for instance the alpha glass on my pending mod HYPERION, in the pits and in vehicle editor you get this same effect on the mirror turn signals. But they seem to be corrected once you spawn on track, this windscreen is not fixing itself.
I've tried, flipping tris, single and double sided, moving the page with S_glass_alp up and down the list to change it's order in the Textures tab in the editor. Nothing works so far.
