The VTXS project was born to challenge the modern graphics trend of smearing everything with TAA and upscaling. The philosophy behind VTXS is that everything stays perfectly sharp, regardless of camera speed.

Screen Space Demo

VTXS
This shader introduces a lighting system developed exclusively for VTXS.

Each emissive pixel visible on screen illuminates the scene and casts shadows.
The noise level is low enough for real time gameplay without requiring denoising. However, a denoiser is still present as an optional feature.

While being a demo this shader is intended to be used for gameplay, so all features necessary for a complete and playable experience are planned.

Implemented Features

Screen Space Path Tracing
Physically Based Atmosphere
Full roughness range specular reflections
Volumetric clouds
Godrays
Subsurface Scattering
Variable penumbra shadows
Bloom
Eye adaptation
Screen Space Raytraced Refraction
GBAA Anti-aliasing

Big thanks to jbritain for making vloumetric clouds for VTXS!

It is highly recommended to use a PBR resource pack, as the integrated PBR system is very limited.

The shader now works on Intel GPUs, however, there may still be issues. Please report any issues in my Discord server.
