Adding support for blending the terain detail material with the macro material. (#7557) 
* Adding support for blending the terain detail material with the macro material. Also includes several bug fixes
- The detail materail manager wasn't querying for default terrain region materials when it initializes, so it was missing some creation events that it would later get destruction events for and explode.
- Change the way the default material weights against other surface weights to avoid some discontinuities
- Fixed an issue where a default material id wouldn't initialize as invalid.

Signed-off-by: Ken Pruiksma <pruiksma@amazon.com>

* Several improvements and bug fixes
- Adding explicit creation / destruction events for material regions.
- Material regions will no longer try to "hide" when they don't have any materials
- Default detail materials will now only be used in areas where there are no other material assignments
- Fixed a bug where materials might not show up on surfaces when they were assigned to multiple regions or surface tags.

* Simplified loop that assigns materials based on surface tags. Slightly simplified shader code regarding detail material id coordinates.

* Fixes from PR review

* Making sure region changed doesn't get announced in the case where the old and new regions are both invalid.

O3DE (Open 3D Engine)

O3DE (Open 3D Engine) is an open-source, real-time, multi-platform 3D engine that enables developers and content creators to build AAA games, cinema-quality 3D worlds, and high-fidelity simulations without any fees or commercial obligations.

Download and Install

This repository uses Git LFS for storing large binary files.

Verify you have Git LFS installed by running the following command to print the version number.

git lfs --version

If Git LFS is not installed, download and run the installer from: https://git-lfs.github.com/.

Install Git LFS hooks

git lfs install

Clone the repository

git clone https://github.com/o3de/o3de.git

Building the Engine

Build requirements and redistributables

For the latest details and system requirements, refer to System Requirements in the documentation.

Windows

Optional

  • Wwise audio SDK
    • For the latest version requirements and setup instructions, refer to the Wwise Audio Engine Gem reference in the documentation.

Quick start engine setup

To set up a project-centric source engine, complete the following steps. For other build options, refer to Setting up O3DE from GitHub in the documentation.

  1. Create a writable folder to cache downloadable third-party packages. You can also use this to store other redistributable SDKs.

  2. Install the following redistributables:

    • Visual Studio and VC++ redistributable can be installed to any location.
    • CMake can be installed to any location, as long as it's available in the system path.

  3. Configure the engine source into a solution using this command line, replacing <your build path>, <your source path>, and <3rdParty package path> with the paths you've created:

    cmake -B <your build path> -S <your source path> -G "Visual Studio 16" -DLY_3RDPARTY_PATH=<3rdParty package path>

    Example:

    cmake -B C:\o3de\build\windows -S C:\o3de -G "Visual Studio 16" -DLY_3RDPARTY_PATH=C:\o3de-packages

    Note: Do not use trailing slashes for the <3rdParty package path>.

  4. Alternatively, you can do this through the CMake GUI:

    1. Start cmake-gui.exe.
    2. Select the local path of the repo under "Where is the source code".
    3. Select a path where to build binaries under "Where to build the binaries".
    4. Click Add Entry and add a cache entry for the <3rdParty package path> folder you created, using the following values:
      1. Name: LY_3RDPARTY_PATH
      2. Type: STRING
      3. Value: <3rdParty package path>
    5. Click Configure.
    6. Wait for the key values to populate. Update or add any additional fields that are needed for your project.
    7. Click Generate.

  5. Register the engine with this command:

    scripts\o3de.bat register --this-engine

  6. The configuration of the solution is complete. You are now ready to create a project and build the engine.

For more details on the steps above, refer to Setting up O3DE from GitHub in the documentation.

Setting up new projects and building the engine

  1. From the O3DE repo folder, set up a new project using the o3de create-project command.

    scripts\o3de.bat create-project --project-path <your new project path>

  2. Configure a solution for your project.

    cmake -B <your project build path> -S <your new project source path> -G "Visual Studio 16"

    Example:

    cmake -B C:\my-project\build\windows -S C:\my-project -G "Visual Studio 16"

    Note: Do not use trailing slashes for the <3rdParty cache path>.

  3. Build the project, Asset Processor, and Editor to binaries by running this command inside your project:

    cmake --build <your project build path> --target <New Project Name>.GameLauncher Editor --config profile -- /m

    Note: Your project name used in the build target is the same as the directory name of your project.

This will compile after some time and binaries will be available in the project build path you've specified, under bin/profile.

For a complete tutorial on project configuration, see Creating Projects Using the Command Line Interface in the documentation.
