SamplerSchedulerIterator
## Sampler Scheduler Iterator Iterates over **sampler x scheduler** combinations one pair per execution. Outputs each pair to connected nodes (e.g. KSampler, Aligned Text Overlay). Node title updates automatically: `Iterator: Step 3 / 12`. Queue stops automatically after the last combination. > **Note:** Press **Refresh** before first use. This reads all installed > samplers and schedulers from ComfyUI and writes the reference file. > The counter resets to 0. --- ### Inputs This node has no inputs. Configure combinations in `.\ComfyUI\custom_nodes\ComfyUI-rogala\config\sampler_scheduler_user.json`. ### Outputs | Pin | Type | Description | |---|---|---| | `sampler_name` | SAMPLER | Current sampler — connect to KSampler. | | `scheduler` | SCHEDULER | Current scheduler — connect to KSampler. | | `external_text` | STRING | `"sampler | scheduler"` label — connect to Aligned Text Overlay. | ### Example Edit `config/sampler_scheduler_user.json` to select combinations: ```json { "samplers": ["euler", "dpmpp_2m", "dpmpp_3m_sde"], "schedulers": ["karras", "simple"] } ``` Total = samplers x schedulers (here: 3 x 2 = **6 runs**). Copy names from `config/sampler_scheduler.json` (generated by Refresh). Unknown names are silently ignored.
