RTX Remix End Context

Every sentence needs a period, and every RTX Remix REST API workflow needs an RTX Remix End Context. It's the closest thing this pack has to a terminal node: you chain your REST API nodes through their context inputs - Start Context, then Get Layers, Create Layer, Ingest Texture, whatever - and End Context sits at the far end, telling ComfyUI "this is where the graph finishes."

Why does that matter? ComfyUI only executes a graph when something marks it as an output. A chain of nodes that all pass a context around but never terminates will happily sit there and do nothing when you hit Queue - there's no terminal node to trigger. End Context is that trigger. It's flagged as an output node in the schema, so it shows up in the queue and makes the whole chain evaluate. Its only input is context, and it has no outputs. That's not an omission, that's the design: it's a checkpoint, not a data node.

Think of it this way: RTX Remix Start Context (which takes an address and port and produces the RTXRemixContext) is the head, and End Context is the tail. Everything in between threads the same context object, which also dictates execution order - nodes won't run until the node feeding their context has run. That ordering guarantee is the real superpower of the pack's context system, and End Context is what closes the loop so the order actually resolves.

Inputs:

• context (RTXRemixContext) - the only input. It doesn't do anything with it beyond existing, but it needs it, because the context is the thread that pulls the whole graph forward.

Outputs: none. It's an output node in the ComfyUI sense - it terminates the graph - but it emits nothing itself.

Install: ships in NVIDIAGameWorks/ComfyUI-RTX-Remix. ComfyUI Manager (search "RTX Remix") or:

cd ComfyUI/custom_nodes
git clone https://github.com/NVIDIAGameWorks/ComfyUI-RTX-Remix
# restart ComfyUI

Needs ComfyUI v0.3.48+ (V3 schema) and, for the rest of the graph, a running RTX Remix Toolkit. End Context itself doesn't call the Toolkit - its job is purely organizational.

Where people get burned: forgetting it. You'll build a nice REST API graph, hit Queue, and nothing happens - no error, no output, just silence. Before you blame the Toolkit or the port, check you have an End Context hanging off the last node. It's the single most common "why is my workflow dead" answer in this pack. Also, don't put it in the middle of a graph - it terminates evaluation, so anything meant to run after it simply won't.
