Fixing ComfyUI Minimax H3 upscaler's model path discovery for external directories
Slight-Living-8098 · reddit · 2026-08-26
A user fixed the ComfyUI Minimax H3 Latent Upscaler nodes failing to find models stored in external directories configured via extramodelpaths.yaml.
Root cause: the original nodes took only the first registered directory via getfolderpaths(...)[0] and searched it with glob(), ignoring extra paths and subdirectories.
Fix: discovery now delegates to ComfyUI using folderpaths.getfilenamelist("latentupscalemodels"), which covers all registered paths and subdirectories, and loading uses getfullpath(). Both 2D and 3D nodes were patched.
Large model files no longer need to be copied into the main models folder. The fixed branch is dev/modelsearchdir on GitHub (badgids/ComfyuiMinimaxh3latentUpscaler); clone it into customnodes and restart ComfyUI.
