MovieFocus can only enable the manual focusing features when you have selected one of the supported shaderpacks. That's because MovieFocus patches the selected pack and adds hooks so that it accepts the manual focusing input. The following list captures all of the currently supported shaderpacks. Feel free to open an issue or even start a pull request if your favorite pack is missing.
- Versions 10.0 and 10.1 of SEUS by Sonic Ether. The latest version 11.0 is also supported, but since DoF is disabled there, you have to manually enable it first.
- Versions 1.0 and 1.1 of OnlyDoF by MrY.
- Version 6 of Chocapic13's Shaders by Chocapic13. Note that derived shaderpacks like SFLP or Lagless Shaders are detected, and then are probably, but not guaranteed to be supported.
