By some weird act of cloaking, the GTSC Faustus is nearly invisible in FRED and in FS2. I say nearly because LOD2 and 3 are visible. It isn't a code thing since it was invisible in exes dating back to May, and I have seen Faustuses since then. Looking in the media VP's, the science01-01a texture in mv_models.vp is a 512x1553 pcx (non-standard power of two height), but its shine and glow are standard sizes. And when I look at the science01-01a texture in mv_textures.vp, the texture is a 1024x2048 dds.
So I was able to fix this by taking the texture in mv_textures.vp and putting it in /data/maps. Anyone else had this problem?
