Adam's presets for the Prepar3D Tweak Assistant (PTA).
NEW!! 18 Jan 2018: preset Adam_26_02
Optimised for the recently released REX Skyforce3D - though all presets here should work well with REX4/TD, AS/ASCA and FEX. PTA is available from www.simtweaks.com.
Note: Preset 26_02 works fine with P3Dv4.2 + PTA 26.01.
PTA presets with natural and balanced palettes that will work at all times of the day, with all seasons and all sky/cloud textures (regardless of which program is used to generate them).
Using a different preset to suit the palettes for each P3D season would require frequent sim restarts and rebuilds of the shaders cache (particularly if you jump from one hemisphere to another in the same session) - so using a single year-round preset is much more practical. All the presets here are designed to work this way.
These presets require HDR mode in P3D to be enabled: make sure you set the correct values for each preset. Though HDR values can be tweaked "live" in P3D (to suit user preferences or weather conditions), bear in mind that even small changes in settings can have a significant impact on the final output.
If you find you need to make more drastic (or permanent) adjustments to the preset, see Customising below.
Sky textures have a HUGE impact on the overall palette in P3D (on sky, terrain and even aircraft) so, if you are using live weather + texture generation (AS or ASN etc.), you may occasionally get some unpredictable results. For this reason, I prefer a fixed day texture set for the full 10-day cycle. I use OPUS Live Weather to vary the weather system only (ie. cloud coverage, visibility etc. - no changes to textures), giving me plenty of variation without disturbing the overall colour balance.
Adam_26_02 uses the default REX SkyForce3D theme as a base (for clouds and sky) - with REX/TD supplying the ground & water textures. As soon as I've settled on a new theme, I'll post the details here.
For my older presets (pre-26_02), I combined REX/TD (sky, ground, water) with FEX (clouds):
REX Sky textures 1: Dawn: 22 Chill | Day: 14 Fair | Dusk 03 Dust ... or ...
This presumes you already have a fully working version of PTA on your system. If starting totally from scratch, please check out Matt's site (and the Avsim forums) for fresh install instructions.
It may take a while for the textures/shaders to rebuild the first time you run P3D after a preset change - this is normal.
Adam_PTA_25_04 : current/latest (for P3Dv4/PTA 2.52)
Changes from Adam_PTA_25_03:
25_04 is a minor update from 25_03 but, for the first time, this new preset comes in three "flavours": REX, FEX and ASCA. Though they're similar, each has individual tweaks - and the required P3D HDR settings will be different in each case. You can always "mix and match" - just load up a different preset and apply it.
I've found that ASCA in particular seems to be affected by sky colours more, so there's an alternative set of P3D HDR settings to try.
3 presets: REX | FEX | ASCA DOWNLOAD

Flight Environment X P3Dv4 HDR settings:
Active Sky + ASCA P3Dv4 HDR settings (two to try):
Adam_PTA_26_02 : current/latest (for P3Dv4.1/PTA 2.6 only)
26_02 is a minor update to 26_01 and is optimised for the newly released REX Skyforce3D. A full list of changes is in the readme file in the archive.

Customising presets: quick tips
All systems are different, so if you feel you need to make further adjustments, here are some places to look:
Preset filenames indicate the main PTA version (XX) and preset number (YY), in the form Adam_PTA_XX_YY.zip. Don't use presets for different or non-matching *main* PTA versions, as parameters may have been added, renamed or even removed. Using presets for different PTA *sub* versions (eg. PTA 2.10, PTA 2.11) is fine.
