DISCLAIMER: I cannot continue working on this project because of the war started by russia (f**k you) in Ukraine.

Hello! This is my attempt to create a Vulkan renderer for old Unreal Engine based games (Rune, Unreal Tournament, etc.). Inspired by kentie

This is a work in progress and I have no commitments. For now I am concentrating only on Windows support for quick start, but later might add linux build (who knows). At the moment I can play Unreal Tournament 1999 v436 is playable, I have not tried other games yet.

What is implemented

• Baseline functionality. I beleive all existing functionality is there, though I can miss something.

What is missing

• Optimization & Mem/Resource management. Code is not optimized at all and was written for correctness first. I am planning to optimize it at some point (this should not be hard). Expect occasional crashes due to descriptor sets, exceeding amount of mem allocations in vulkan and other. Validation is disabled on purpose :-)
• Mipmap support is missing (easy to add)
• Build scripts. I did not want to spend time on not fun stuff, so here you are.. VS project which is setup for Unreal Tournament Debug Win32

What could be added

• RayTraced something, not sure though, because there is not so much freedom all triangles come as pretransformed triangle soup in view space, so not that much useful for ray tracing.
• Soft particles (should be easy)

Prerequisites

You need to have original game files to run the game. This repo will only include files necessary to build a driver.

Building

To build a driver dll you need to have header and lib files for your game. You can either create a 'game' folder here and put them there or just make a symlink.

Game folder structure: game\<GameName>\Core\Inc game\<GameName>\Core\Lib game\<GameName>\Engine\Inc game\<GameName>\Engine\Lib

After this, open solution, select correct configuration and build a dll. Resulting filesshould appear in 'packages' folder, copy them to your game 'System' folder.
