Adam's presets for the Prepar3D Tweak Assistant (PTA).
NEW! PTA 2.60 preset 26_01
Latest preset: Adam_26_01 for PTA 2.60 (P3Dv4.1).
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).
Creating different presets to suit palettes for all the P3D seasons 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 - and newer presets have the recommended HDR settings hard-coded in the "Tweak main config" section. HDR can be tweaked "live" in P3D to suit user preferences or weather conditions, but bear in mind that even small changes in HDR values can have significant effects on 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 dynamic 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.
I combine REX/Texture Direct (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_03 : current/latest (for P3Dv4/PTA 2.5 only)
P3Dv4 HDR settings: Brightness: 0.71 | Bloom: 0 | Saturation: 0.87. DOWNLOAD
Changes from Adam_PTA_25_02:
25_03 has some blue removed from various settings and softer cloud shadows so that the landscape isn't overly dark in cloudy/overcast conditions. I kept reducing bloom (an effect I've always had reservations about) until it was almost zero. In the end, I turned it right off!
Adam_PTA_26_01 : current/latest (for P3Dv4.1/PTA 2.6 only)
Changes from Adam_PTA_25_04:
26_01 is a minor update from 25_04. Unlike 25_04, this new preset comes in only one "flavour".
P3Dv4.1 HDR settings: Brightness: 0.75 | Bloom: 0.10 | Saturation: 0.94
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.
