Feature Request: Motion Vector output support for Super Resolution Mod (DLSS/FSR/XeSS)

[C-zaha-Chell-Tia]

Feature Request

First of all, a huge thank you to the Complementary team for creating and maintaining such an incredible shaderpack!

I would like to respectfully request the addition of motion vector output support in Complementary Shaders for compatibility with the MC Super Resolution Mod (DLSS / FSR3 / XeSS).

Implementation Details

1. Primary Requirement — V3 Specification Support:

   • MC Super Resolution Mod version 9.0+ requires the V3 interface specification for motion vector output. We would greatly appreciate implementation of V3 support for full compatibility with the latest builds.

2. Secondary Request — V2 Fallback Mode:

   • If feasible, including a V2 fallback option alongside V3 would be extremely beneficial for stability.
   • Technical Background: In complex Forge 1.20.1 setups—particularly environments utilizing Sinytra Connector or heavy Mixin-based dependency mods—v9.0+ of the Super Resolution mod can occasionally cause Mixin errors or startup crashes. Having a V2 fallback allows players to run older/more stable mod builds safely without losing shader motion vector functionality.
