Build Prerequisites

• Install libKTX. Find the latest release in the Releases tab and install it to D:/Program Files/KTX-Software. If your system does not have a D drive, you'll have to modify RenderCore/extern/extern.cmake to set KTX_DIR to the directory you installed libKTX to
• Optinally, install Nvidia's Optical Flow SDK to RenderCore/extern/Optical_Flow_SDK_5.0.7
• You'll also need to install the Vulkan SDK and add its bin directory to your PATH
• Download "the glTF Sponza" from https://github.com/KhronosGroup/glTF-Sample-Models/tree/master/2.0/Sponza. You'll need to manually copy it to your working directory before running

Android build

• Symlink or copy the folder RenderCore/Shaders/ to app/src/main/shaders/
• Copy the glTF Sponza to app/src/main/assets/Sponza/
• Build the Gradle project in app/
• Run the APK

Windows build

• Download gltfpack from https://github.com/zeux/meshoptimizer and place it in your PATH
• Copy the glTF Sponza to Windows/build/Sponza/
• Symlink (or copy) the folder RenderCore/shaders/ to Windows/build/shaders/
• Build the cmake project in Windows
• Run the SahWindows Visual Studio project
• If you want to run from outside Visual Studio, either copy Sponza and the shaders to Windows/build/Debug or copy the SahWindows executable to Windows/build

Other OSs

Unsupported. You could probably modify the Windows build to also run on Linux, but I've had no reason to

Known-good configurations

• This program definitely works on a Nvidia RTX 2080 Super GPU, and a Mali G710 GPU. Other Vulkan implementations may or may not support all the required features
