VXGI test

This is a test of NVIDIA's VXGI combined with BrickGame. VXGI provides much higher quality global illumination than Light Propagation Volumes, but at some additional cost. It requires a much more powerful GPU than the non-VXGI version of BrickGame. It runs at 20-30 FPS on my Geforce 980 at 1920x1080, so you will at least have to lower the resolution on less powerful GPUs. I haven't tested it on an AMD GPU; it should work, but I expect the performance will be worse than on a comparable NVIDIA GPU.

It was built with some local code changes that aren't reflected in the code in the BrickGame repository, in addition to being built against a slightly modified version of GalaxyMan's 4.8 GameWorks merge (https://github.com/GalaxyMan2015/UnrealEngine/tree/4.8_NVIDIA_Techs).

Because of the way GitHub works, I couldn't post a release without it tagging and including a zip of the source code. That source code does not correspond to this build!

v0.9

This release is mostly just optimizations.

v0.8

• Emissive bricks now illuminate their surroundings
• Rebuilt the sky to have a moon and clouds (requires changes to the engine code that aren't in UE4.1)
• Made terrain generation faster
• Made render chunks larger (and increased the draw distance)

v0.7

Changes since v0.6:

• Added simple ambient occlusion, so interiors no longer receive ambient lighting
• Tweaked day-night cycle, atmospheric scattering, and ambient lighting
• Render grass material only on the top of grassy dirt bricks
• Added glowing brick material (doesn't affect other bricks yet)
• Prevent brick placement on top of the player
• Optimization of rendering data setup

Keys:
Left Mouse Button: Add a brick of the selected material
Right Mouse Button: Remove a brick
Middle Mouse Button: Select the brick material you're aiming at
Mouse wheel: Change selected brick material
