First version of temporal antialiasing and contrast adaptive sharpening for GA. Works well in most cases but still has a few issues that will need additional time. This is only the passes and shaders with no exposure to the editor. TAA and CAS can be turned on by enabling their respective passes in the pipeline. All of the code has been previously reviewed in smaller PRs into the taa_staging branch: aws-lumberyard-dev#29 aws-lumberyard-dev#53 aws-lumberyard-dev#73 aws-lumberyard-dev#79 aws-lumberyard-dev#84 Main issues: - Bloom doesn't play nice with TAA and seems to greatly amplify any flickering - AuxGeom jitters with the camera, so TAA doesn't currently work well in editor - Transparencies don't have correct motion vectors. History rectification keeps this from looking too bad, but could still be improved - There is still more that could be done to inhibit flickering, usually from specular aliasing - Motion vectors aren't correct on POM unless PDO is turned on, which can result in some blurring during motion. - SSAO can contribute to flickering in its default half res configuration. Changing this to full res mitigates the problem. Squashed merge of the following: * [ATOM-13987] Initial checkin of Taa pass. * TAA pass setup WIP. (does not work yet due to pass configuration issues). * Taa WIP - Camera motion vectors fixed and hooked up. TAA does simple reprojection and rejection based on depth. * Small update to use lerp and add some comments. * Fix issue with attachments not being set up on bindings at initialization. Fixing issue with half-pixel offsets in TAA shader * - Motion vector passes now use the same output with mesh motion vectors overwriting camera motion vectors. - Taa pass now works with multiple pipelines. - Cleaned up TAA shader a bit. * Fixes from PR review. * Adding check for multiple attachments of the same name with different resources in Pass::ImportAttachments(). * Adding camera jitter with configurable position count. Updated TAA to blend in tonemapped space. * Fixes from PR review. Fixing camera motion vectors for background (infinite distance) * Updates to taa shader from PR review * Adding a rcp input color size. * Fix comment on PassAttachment::Update() * Updates for PR review. * Fixing missing const on the FrameAttachment* in Pass's call to FindAttachment() * Taa WIP - Adding filtering to both the current pixel and history. Adding rectification based on variance clipping. Adding some basic anti-flickering. Removing rejection based on depth. * Updates from PR code review. Mostly better commenting and naming. * Adding contrast adaptive sharpening based on AMD FidelityFX CAS to help with the softness added by TAA. * Changing to using luminance for sharpening instead of just green. Added some comments. * Moving Taa's NaN check to a better location. Disabling TAA and sharpening in prep for check in. * Updates from PR feedback.

Download and Install
This repository uses Git LFS for storing large binary files. You will need to create a Github personal access token to authenticate with the LFS service.
To install Git LFS, download the binary here: https://git-lfs.github.com/.
After installation, you will need to install the necessary git hooks with this command
git lfs install
Create a Git Personal Access Token
You will need your personal access token credentials to authenticate when you clone the repository and when downloading objects from Git LFS
Create a personal access token with the 'repo' scope.
During the clone operation, you will be prompted to enter a password. Your token will be used as the password. You will also be prompted a second time for Git LFS.
(Recommended) Verify you have a credential manager installed to store your credentials
Recent versions of Git install a credential manager to store your credentials so you don't have to put in the credentials for every request.
It is highly recommended you check that you have a credential manager installed and configured
For Linux and Mac, use the following commands to store credentials
Linux:
git config --global credential.helper cache
Mac:
git config --global credential.helper osxkeychain
Clone the repository
> git clone https://github.com/aws-lumberyard/o3de.git
Cloning into 'o3de'...

Building the Engine
Build Requirements and redistributables
Windows
- Visual Studio 2019 16.9.2 minimum (All versions supported, including Community): https://visualstudio.microsoft.com/downloads/
- Install the following workloads:
- Game Development with C++
- MSVC v142 - VS 2019 C++ x64/x86
- C++ 2019 redistributable update
- Install the following workloads:
- CMake 3.19.1 minimum: https://cmake.org/files/LatestRelease/cmake-3.19.1-win64-x64.msi
Optional
- WWise - 2019.2.8.7432 minimum: https://www.audiokinetic.com/download/
- Note: This requires registration and installation of a client to download
- You will also need to set a environment variable:
set LY_WWISE_INSTALL_PATH=<path to WWise version> - For example:
set LY_WWISE_INSTALL_PATH="C:\Program Files (x86)\Audiokinetic\Wwise 2019.2.8.7432"
Quick Start Build Steps
-
Create a writable folder to cache 3rd Party dependencies. You can also use this to store other redistributable SDKs.
For the 0.5 branch - Create an empty text file named
3rdParty.txtin this folder, to allow a legacy CMake validator to pass -
Install the following redistributables to the following:
- 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, otherwise it can be installed to:
<3rdParty Path>\CMake\3.19.1 - WWise can be installed anywhere, but you will need to set an environment variable for CMake to detect it:
set LY_WWISE_INSTALL_PATH=<path to WWise>
-
Navigate into the repo folder, then download the python runtime with this command
For the 0.5 branch - Set this environment variable prior to the
get_pythoncommand below:set LY_PACKAGE_SERVER_URLS=https://d2c171ws20a1rv.cloudfront.netpython\get_python.bat -
Configure the source into a solution using this command line, replacing and <3rdParty cache path> to a path you've created:
cmake -B <your build path> -S <your source path> -G "Visual Studio 16" -DLY_3RDPARTY_PATH=<3rdParty cache path> -DLY_UNITY_BUILD=ON -DLY_PROJECTS=AutomatedTestingNote: Do not use trailing slashes for the <3rdParty cache path>
-
Alternatively, you can do this through the CMake GUI:
- Start
cmake-gui.exe - Select the local path of the repo under "Where is the source code"
- Select a path where to build binaries under "Where to build the binaries"
- Click "Configure"
- Wait for the key values to populate. Fill in the fields that are relevant, including
LY_3RDPARTY_PATHandLY_PROJECTS - Click "Generate"
- Start
-
The configuration of the solution is complete. To build the Editor and AssetProcessor to binaries, run this command inside your repo:
cmake --build <your build path> --target AutomatedTesting.GameLauncher AssetProcessor Editor --config profile -- /m -
This will compile after some time and binaries will be available in the build path you've specified
Setting up new projects
- While still within the repo folder, register the engine with this command:
scripts\o3de.bat register --this-engine - Setup new projects using the
o3de create-projectcommand. In the 0.5 branch, the project directory must be a subdirectory in the repo folder.<Repo path>\scripts\o3de.bat create-project --project-path <your new project path> - Register the engine to the project
<Repo path>\scripts\o3de.bat register --project-path <New project path> - Once you're ready to build the project, run the same set of commands to configure and build:
cmake -B <your project build path> -S <your new project source path> -G "Visual Studio 16" -DLY_3RDPARTY_PATH=<3rdParty cache path> // For the 0.5 branch, you must build a new Editor for each project: cmake --build <your project build path> --target <New Project Name>.GameLauncher Editor --config profile -- /m // For all other branches, just build the project: cmake --build <your project build path> --target <New Project Name>.GameLauncher --config profile -- /m
