I've now upgraded to P3Dv4 + PTA2.52. Neither of the two texture systems that I use (REX/TD and FEX) have been updated for P3Dv4 yet, but re-pointing them to P3Dv4 works fine (providing you don't install water textures or animations, as those have changed in v4).

PTA is available here: Matt Davies' comments: @MattDaviesHD.

Latest preset: Adam_25_03  for PTA 2.51/2.52 (P3Dv4 only).

Tweaking Tips | Benchmarking Scenarios

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/cloud Textures

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: Dawn: 22 Chill | Day: 14 Fair | Dusk 03 Dust.
FEX cloud theme: When logged into the FEX server, try finding Adam P3dv3 PTA 20-08, author Adam Banks.

Preset Installation

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.

  1. Download the preset zip archive and extract it to somewhere convenient.
  2. Copy the *.ini file into your PTA folder.
  3. Start PTA: navigate to and open the new preset.
  4. Click on "Apply Preset". This will apply the preset and clear your shaders cache.
  5. Launch P3D - and check that your HDR settings are set to the recommended values for the new preset.

It may take a while for the textures/shaders to rebuild the first time you run P3D after a preset change - this is normal.

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!

  • HDR Values changed (see above).
  • Cloud shadows weakened slightly.
  • Blue (in various settings) reduced slightly.
  • Haze/fog reduced slightly..

Customising presets: quick tips

All systems are different, so if you feel you need to make further adjustments, here are some places to look:

  • Too blue overall? Enable the Scene tone adjustment post-processing filter then adjust the blue value - OR - lower the blue value (balanceZ) in Vibrance.
  • Water too blue? Tweak the Water Saturation value (to around 0.78 or below). Turning down the blue in the Haze effect and Rayleigh filters may also help.
  • Water: repeating textures? These will depend on the current water textures in use. Try experimenting with the two Waves size parameters.
  • Too dark in fully overcast conditions? Temporarily raise the HDR Brightness value (in P3D) or (in PTA) slightly raise the values of Objects lighting/Ambient sunlight ratio and Terrain lighting/Ambient sunlight ratio.

Preset filenames indicate the main PTA version (XX) and preset number (YY), in the form 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.
