VRGDG Image Switch (Multi Dynamic)

When your reference-image pool grows past four, the fixed-slot switches stop cutting it. VRGDG Image Switch (Multi Dynamic) is the pack's big selector: set image_count anywhere from 1 to 50, click Refresh Inputs, and the node grows the exact number of image ports you asked for. Then one index string - 1,2,5, or the word all - picks which of them come out.

How it works. The node ships with image_count (default 4) and an index string. Bump image_count and refresh, and the optional image inputs materialize to match - no more staring at 46 dead ports when you only need six. Selection follows the pack's string-index convention: a single number for one image, a comma list (1,2,5) for a batch, all for everything connected. The dynamic port count is what makes this the go-to when your workflow's reference set changes between projects - one node flexes from "I need three refs" to "I need forty storyboard frames."

The inputs. index and image_count are required; the 50 optional image ports appear as needed. Note the node doesn't know how many images you plan to connect - image_count is the ceiling you're declaring, so set it to what you need, refresh, then wire up.

The output. image - a single image or a batch, depending on your selection string.

The mechanism behind the curtain. That Refresh Inputs button is powered by a small JS extension shipped with the pack (VRGDG_ImageSwitchMulti_dynamic.js) - it's what actually adds and removes the input ports in the UI. If you've installed the pack and the button doesn't work, that's a frontend-loading problem, not a node-logic problem.

Installing. It's in the vrgamedev pack:

cd ComfyUI/custom_nodes
git clone https://github.com/vrgamegirl19/comfyui-vrgamedevgirl

or install via ComfyUI Manager and restart.

Troubleshooting. Two classic issues. First, the stale-node problem: if you changed image_count and the ports didn't change, you forgot to click Refresh Inputs - that's the intended flow. Second, if the refresh button does nothing at all, it's usually a cached JS file: hard-refresh the ComfyUI page (Ctrl+Shift+R) or clear the browser cache, and if that fails, reinstall the pack so the web folder is present. And as with all the pack's switches, 0 in an index string is a sentinel, not a real image - if selecting 0 returns nothing, that's by design.
