Shader Enhancements in Leadwerks 4.4

Leadwerks Game Engine 4.4, scheduled for release soon, features some updated and enhanced visual effects.  In this blog I will talk about some of the adjustments I made.  Having "The Zone" scene that Aggror recreated actually helped a lot to see how shaders could be improved.

Bloom / Iris Adjustment / HDR

The bloom and iris adjustment shaders have been updated to give bloom a wider and softer blur.  Iris adjustment is faster and more intense now, which will make the outdoors areas seem very bright when you are indoors, and the indoors areas will look very dark when you are outdoors.

SSAO
The SSAO shader has multiple passes added to it, resulting in a much smoother yet crisp result.

Vegetation Shaders

A new vegetation shader called "groundrocks" will make objects align to the terrain.  This lets you easily paint clusters of rocks all across a landscape, resulting in a nice chunky look that breaks up boring heightmap terrain.

Built-in Fog
Although several fog shaders have been available in the Workshop for some time, version 4.4 adds a built-in distance fog you can use to make spooky scenes.

The fog is built into several shaders in order to give correct reflections.  It works great with water.  Notice the reflection is also foggy, and the water itself is affected by fog, giving a nice misty look to the far side of the lake.

You can try Leadwerks Game Engine 4.4 right now by opting into the beta branch on Steam.

I know the documentation must have taken a lot of time but as I said before, it seems like Leadwerks is getting a lot of good (and relevant) upgrades recently.

      I thought I would share my experience on this; if you're working on Multiplayer, you will need to protect your packets. The solution is simple, let's go through how we can achieve this by implementing what Valve calls "challenge codes". (Some reading on the topic from Valve here: https://developer.valvesoftware.com/wiki/Master_Server_Query_Protocol#Challenge_response).
      Disclaimer: this doesn't cover other security techniques like authoritative server or encryption.
      So, I've worked on Border Recon last year (I think) and I needed a way to protect my server/client packets. There was no need for me to re-invent the wheel, I just had to copy what Valve has had for a  long time - challenge  codes.
      The idea behind challenge codes is similar to Captcha, but not exactly. Think of it like this: for every packet submitted to the server, it must be verified - how? By requiring the client to solve challenges our server provides.
      To implement this we need to have the following:
      A randomised formula in the server i.e.: a = b * c / d + e or a = b / c + d - e, be creative - it can be any combination of basic arithmetic or some fancy logic you like and can be however long as you want - do consider that the longer the formula, the more work your server has to do to make the computation.  Copy the same formula to the client. A random number generator.  So the idea here is:
      (Server) Generate a random number (see 3 above) of which the result would become the challenge code, (Server) run it through our formula and record the result. (Client) And then, we hand over the challenge code to the client to solve (an authentic client would have the same formula implemented in its program as we have on the server). For every packet received from the player, a new challenge code is created (and the player is notified of this change by the server in response). For every other packet, a new challenge code is created. (Client) Every packet sent to the server by the client must have a challenge code and its answer embedded.  (Server receives the packet) Run the challenge code again to our formula and compare the result to the answer embedded on the client's packet. (Server) If the answers are different, reject the packet, no changes to the player's state. The advantage(s) of this strategy in terms of achieving the protection we need to secure our server:
      - For every packet sent, new challenge code is created. Typically, game clients (especially FPS) will update its state in a matter of ms so even if a cheater is successful at sniffing the answer to a challenge code it would be invalidated almost instantaneously. 
      - Lightweight solution. No encryption needed. 
      Disadvantage(s):
      - The formula to answering the challenge code is embedded to the client, a cheater can de-compile the client and uncover the formula. Luckily, we have other anti-cheat solutions for that; you can implement another anti-cheat solution i.e. checking file checksums to verify the integrity of your game files and more (there are third-party anti cheat solutions out there that you can use to protect your game files).

      New commands in Turbo Engine will add better support for multiple monitors. The new Display class lets you iterate through all your monitors:
      for (int n = 0; n < CountDisplays(); ++n) { auto display = GetDisplay(n); Print(display->GetPosition()); //monitor XY coordinates Print(display->GetSize()); //monitor size Print(display->GetScale()); //DPI scaling } The CreateWindow() function now takes a parameter for the monitor to create the window on / relative to.
      auto display = GetDisplay(0); Vec2 scale = display->GetScale(); auto window = CreateWindow(display, "My Game", 0, 0, 1280.0 * scale.x, 720.0 * scale.y, WINDOW_TITLEBAR | WINDOW_RESIZABLE); The WINDOW_CENTER style can be used to center the window on one display.
      You can use GetDisplay(DISPLAY_PRIMARY) to retrieve the main display. This will be the same as GetDisplay(0) on systems with only one monitor.

      A huge update is available for Turbo Engine Beta.
      Hardware tessellation adds geometric detail to your models and smooths out sharp corners. The new terrain system is live, with fast performance, displacement, and support for up to 255 material layers. Plugins are now working, with sample code for loading MD3 models and VTF textures. Shader families eliminate the need to specify a lot of different shaders in a material file. Support for multiple monitors and better control of DPI scaling. Notes:
      Terrain currently has cracks between LOD stages, as I have not yet decided how I want to handle this. Tessellation has some "shimmering" effects at some resolutions. Terrain may display a wire grid on parts. Directional lights are supported but cast no shadows. Tested in Nvidia and AMD, did not test on Intel. Subscribers can get the latest beta in the private forum here.
