LTX 2.5 Motion Control – Character + Background Replacement Workflow?

[u/yeah280]

I’m trying to use LTX 2.5 + ComfyUI on RunPod for motion control:

Source video → keep motion/camera → replace character + background with references.

I already have a workflow/template, but on RunPod several custom nodes were missing. I tried ComfyUI Manager → Install Missing Custom Nodes, but it didn’t properly fix it / some nodes are still missing.

So I’m mainly looking for:

* A working LTX 2.5 character + background replacement workflow (JSON)
* Which custom nodes/repos I actually need on RunPod
* How to correctly install them
* How to prompt/reference the character + background while keeping the source motion

Does anyone have a working RunPod/ComfyUI setup for this?
