The viewmodel of the AUG in the TIOCoop mod is obviously not mounting the classic Swarovski optic I had based the sight targa on. Yesterday, I started feeling that I should fix that. Also took the opportunity to give it a neatish new reticle.
I made a screenshot of the AUG after switching the pos and tpos in the weapon.def, and with that image of the scope up to the eye, drew something that looked like it, slapped some shading on it, and then drew a German #4 with an illuminated red dot. The reticle is mounted 3px low, and that's a fairly consistent 300m zero. The bars and post are my best attempt at making them 5 mrads thick, the thin crosshairs are similarly my best guess at half an mrad thick, and the gap is 10 mrads wide from the center on three sides. The red dot brightness is adjustable.
Edit: The fact that there is a maximum allowable number of valid entries in the weapon.def (54, if I haven't miscounted) annoys me to no measurable end. Imagine my joy at realizing the weapon.def in the TIOCoop mod that I've been editing for so long actually had a duplicate entry for the thermite packs (which was undoubtedly my mistake), and having deleted it, freed up a valid weapon entry slot, and I could add a semi-fire mode to the AUG.
