Yuri Tryfonov (the original developer of PTA/P3D) has turned his talents to X-Plane – with X-Vision Pro.
After having tried many shader tweak LUA scripts, I’ve decided to stick with the excellent (and free) FlyAGI Tweak Utility (see also the FlyAGI Manual), used with FlyWithLUA NG (v2.7.22).
NOTE: There are substantial differences in lighting between default/native XP scenery and photoreal areas (eg. ORBX TEGB) – and also slight differences in palette between the various ORBX photoreal areas themselves – so the latest preset (140_01) comes in three variations: “ORBX TEGB Photoreal”, “ORBX TEWA Photoreal” and “Native”.
