    [PLUGIN] [WIP] Physical Sky - Weather System

    This is the development thread for the new version of my weather system.
    Earlier this year I posted about the prototype of this system in another thread.
    I encourage you to read through it and in case you have any questions feel free to ask them HERE in this thread!

    I will post mainly videos, pictures and from time to time some breakdowns. I try to answer every question.
    Every kind of feedback and constructive criticism is more than welcome.

    I am currently working on the snow on the ground. It will be followed by puddles and maybe sand.

    Download:
    Current Snow Demo and Test version (UE 4.14.3)

    Updates
    Reworked Snow as Material Function

    Video Demos:

    It looks absolutely fantastic! Are you using POM on terrain or is that tessellation? Also really great snow material with that specular highlights.

      This looks really good. What are your plans for the plugin?

        Update:
        Been working on the look of the snow when melting.
        The snow melts slower in shadows and where vertex paint is applied.

        Sequencer making it really easy to do these videos now!

        Thank you! I use tesselation. No POM right now. I want to use it for footprints though. But 4.11 has a bug where it freezes the pc when you try to use POM in a decal material.

        The plugin will be an advanced version of the prototype seen here.
        In short: A weather system that focusses on the transitions between different weather states. These weather states and the way they transition will be 100% controllable by the user.
        In the future there might be an AI that takes over the control or just parts of it.

        I hope to make it very easy to use and integrate into existing projects. And in the end it should be usable with any kind of art style although I will focus on realism.

          Will this be a paid or Free plugin?

              Oh cool, i asked becouse Epic devs said that terrain is not well fit for tessellation as it creates artifacts, but there are none on your video.

                The finished plugin is going to cost a bit of money.
                I will try to release parts of it for free like the snow material for example. Or the prototype I made but please don't expect too much.

                Oh no this is not a terrain!
                It's the ground mesh from the open world sample scene. I have to try it yet on the terrain. The last time I did it was a huge mess with the performance.
                But it should not be very difficult to convert the material to a POM material.

                  Update:
                  Tested the material on a landscape with slight modifications to use landscape layers instead of vertex colors.
                  As long as Epic is not actively trying to get proper tessellation working on landscapes I may have to rely on POM.
                  There are holes in the surface and the texture coordinates are a total mess for the World Displacement input.
                  Anyways here the video of my test:


                  After that I continued with the main material to add wetness. And I tried a different base material to find out what complications might occur.
                  Right know I only had to adjust the Height Multiplier for the new heightmap and the Snow displacement height.


                  [Edit]
                  Another base material I tested:

                      Update:
                      Reworked the masking and added puddles.
                      To get a better feeling for the look in a more complete and realistic environment I placed some trees and other assets from the Open World Demo project.


                      And with another base material:

                      (yes the trees are on top of the rocks )

                        Neat! Though is the snow melting material just based on the normal pointing away from the sun rather than actually being shadowed?

                          Looks very realistic, could use this in my current project ... as long it is affordable for a strained indie budget, cheers.

                              Are those trees from Epics nature package? They look very good. As usual your videos look very cool aswel. One thing that would be cool is if you could add storms in your weather system that would affect world wind actor and increase wind which would make plants to swing more. Little touch but would add a lot ambience to scene.
