Scheduler Selector (Impact)
The full 16-scheduler dropdown, exported as a wire for Impact samplers
- scheduler
If you run Impact Pack samplers - and if you use FaceDetailer, you probably have Impact Pack installed even if you don't think of it that way - this is the scheduler dropdown you wire in. Scheduler Selector (Impact) exposes the full Impact-style scheduler list as a single output socket: the nine vanilla schedulers, the three AYS presets, and Impact's extras GITS[coeff=1.2], OSS FLUX, OSS Wan and simple_test. Sixteen choices, one scheduler output, done.
How it works
One combo (scheduler_impact, 16 choices) in, one scheduler output out, pure pass-through. The output socket is typed to the Impact scheduler list, so it drops straight into an Impact sampler's scheduler input. That's the whole mechanism - the value of the node isn't cleverness, it's that Impact exposes scheduler as an input socket and something has to source it. This gives you a single, visible, groupable place to make that choice, and it's the only one of the RvTools scheduler selectors that reaches the GITS[coeff=1.2] / OSS FLUX / OSS Wan entries.
When you'd reach for it
Impact's sampler nodes show up mainly in the detailer sub-pass (FaceDetailer's internal KSampler and friends), and the base pass usually runs on vanilla KSampler. If you want both passes sharing one scheduler decision, the two-output ComfyUI+Impact selector is the better fit - this single-output version is for when you only need the Impact side, or when you're wiring the choice through a switch so one node flips schedulers at runtime.
Deprecated
It sits in the DEPRECATED category, and the pack is unmaintained (superseded by ComfyUI_Eclipse). As pass-through plumbing it just works; just don't expect it to track whatever schedulers Impact adds in future releases - the list is frozen in this pack's code.
Installing it
ComfyUI Manager → search ComfyUI-RvTools_v2, install, restart; or clone https://github.com/r-vage/ComfyUI-RvTools_v2 into ComfyUI/custom_nodes. Impact Pack itself is a separate install (Manager: ComfyUI-Impact-Pack). No model downloads.
Gotchas
The v2 rename is the recurring theme with this pack: original v1 workflows reference ComfyUI-RvTools class names and will show this node as missing - that's the reason v2 exists, per the README. One more worth knowing: simple_test is in the list but it's a debug scheduler - you won't want it for real runs, and seeing it in the dropdown is normal, not a sign of breakage.
