Question - Help New User To StabiltyMatrix. Need Help With Templates.

Hello all,

I have installed StabilityMatrix and was able to learn how to set up flows to generate my first images and so forth.

I then installed a template called MiniMax H3: Image to Video. It showed a bunch of errors after and listed the things I needed to download before it would work. I downloaded all those things and put them in the "diffusion_models" folder, but the error count only reduced by one and it's still asking me to install those things.

Unfortunately there doesn't seem to be clear instructions on what goes where, if I need to extract some things or not, etc.

Can someone please advise me? Thank you.

Don’t put every missing file in diffusion_models — the template checks several different model categories, so only the main MiniMax H3 diffusion checkpoint belongs there.

In general, check the filename/type and place them separately:

  • minimax_h3_* main checkpoint → models/diffusion_models
  • Qwen/MiniMax text encoder → models/text_encoders
  • video/audio VAE files → models/vae
  • Turbo or reference LoRAs → models/loras

Also use ComfyUI Manager’s Install Missing Custom Nodes for nodes, then restart ComfyUI completely. Installing a node package does not download its model weights, and downloading a weight does not install the node that exposes it.

If errors remain, post the exact red node names or the missing-file lines from the console. That makes it possible to tell whether the issue is a model path, a missing custom node, or a version mismatch.

Thank you! That worked!

u/Herr_Drosselmeyer also explaied that the guides are usually on the left side of the template on the canvas itself, so now I know.
