Is there a way to make rain look more realistic than this? Thanks

Have been using this guide for ages, rain is much more realistic and looks great.

1. Go to your ShadersHLSL folder in your main P3D directory.
2. Locate the file PrecipParticle.fx and back it up first!

3. Open it in a Notepad type program and locate the following block of text:

   //Control how long streaks face and how big they are.
    float height = precipMaterial.fQuadSize * precipMaterial.fQuadSizeHeightScale;
    float width = precipMaterial.fQuadSize * precipMaterial.fQuadSizeWidthScale;

4. Divide the height and width of the rain particles by adding the following code (highlighted in bold). You don't HAVE to divide both, experiment to your liking!

    //Control how long streaks face and how big they are.
    float height = precipMaterial.fQuadSize * precipMaterial.fQuadSizeHeightScale / 3;
    float width = precipMaterial.fQuadSize * precipMaterial.fQuadSizeWidthScale / 3;

5. Save the file
6. Locate the Shaders folder in %LocalAppData%\Lockheed Martin\Prepar3D v5
7. Delete the Shaders folder (not ShadersHLSL folder)
8. Load the simulator and enjoy your new rain!

 

For anyone using P3D v4, the text in PrecipParticle.fx reads as follows:

  //Control how long streaks face and how big they are.
  float height = cb_fQuadSize * cb_fQuadSizeHeightScale;
  float width = cb_fQuadSize * cb_fQuadSizeWidthScale;

Similar to P3D v5, change the text to the following to get better rain effects:

  //Control how long streaks face and how big they are.
  float height = cb_fQuadSize * cb_fQuadSizeHeightScale / 3;
  float width = cb_fQuadSize * cb_fQuadSizeWidthScale / 3;

Then there is the next level of calcs...

    // Control how long streaks face and how big they are.
    // TBM 03/02/2019 change the calculated value for a smaller looking rain/snow effect.
    float height = cb_fQuadSize * cb_fQuadSizeHeightScale / (2.4 - (cb_uPrecipType * 1.65));
    float width = cb_fQuadSize * cb_fQuadSizeWidthScale / (1.0 - (cb_uPrecipType * 0.25));

    //float height = cb_fQuadSize * cb_fQuadSizeHeightScale;
    //float width = cb_fQuadSize * cb_fQuadSizeWidthScale;

Cheers

I'll try that thanks

I hope that //42 PrecipitFX will be upgraded for P3D sometimes, it was a must have for P3D.

You could update to MSFS!!!

Flight Simmer since 1983 - loving the brilliant Quality Wings 787 and all PMDG models!!

Yes, why not update to MSFS - for all those fabulous planes and fantastic flight models, with state of the art GTN 750/650, perfect autopilot, controllable weather modeling, and I just love that I can choose a date/time and fly historical weather or real world...oh wait... 🤔

I installed the PrecipitFX-Rain effects into v5 and it works! It‘s not looking perfect, but much better than the default rain. You need a v4-fake installation with pathes into v5, but attention: only tick the rain and snow effects.

You could purchase Active Sky.  Works like a charm.

Thanks for helping me with this...problem seems to be solved and rain is looking much better. As for utilizing PrecipFX, how do I create a dummy lead for v5.2?

Maybe I'm missing it, but I can't find any setting within AS to change precipitation particle size?

I have a reg path already setup for this type of pseudo install and by and large it works well.

However when using ORBX Central to install Precipit-FX it fails complaining about error/missing config files such as scenery/terrain etc.

The only way I can do it, is to manually install all the effect/Simobject files, messy , to say the least.

I have been using As for years as well as ASCA. As for Particle size change it is in YOUR MAIN P3D FOLDER/SHADERSHLSL.

As one of the posters advised me, this is the relevant portion of  PrecipParticle.fx. Use Notepad to open and edit the file adding the ./3 to float height and width height. 

//Control how long streaks face and how big they are.
    float height = precipMaterial.fQuadSize * precipMaterial.fQuadSizeHeightScale / 3;
    float width = precipMaterial.fQuadSize * precipMaterial.fQuadSizeWidthScale / 3;
    //Control how long streaks face and how big they are.
   //float height = precipMaterial.fQuadSize * precipMaterial.fQuadSizeHeightScale;
   //float width = precipMaterial.fQuadSize * precipMaterial.fQuadSizeWidthScale;

I know that, but your selective quote of my reply/answer was to what @jfmitch posted regarding AS., and not what it makes out to be when posted out of context.

Which, to my mind, infers that AS has some setting within it to control rain particle size.

AFAIK there is not, and never was, any setting within AS to adjust particle size.

That is why I posed the question .
