Stable Cascade Workflow

instructions.md

https://huggingface.co/stabilityai/stable-cascade/tree/main

stage_b.safetensors and stage_c.safetensors (you can use the bf16 versions) go in ComfyUI/models/unet

stage_a.safetensors goes in ComfyUI/models/vae

and this: https://huggingface.co/stabilityai/stable-cascade/blob/main/text_encoder/model.safetensors goes in the ComfyUI/models/clip/ folder to be loaded with the Load CLIP node in the workflow

Can you help me please? My comfyui dont find these missing nodes:
EmptyLatent and Conditioning.
Searching doesnt return any results. Is there way to manually install this? Can find it. Thanks a lot in advance!

I downloaded the models to the required folders as specified above.
And it started to download:

model.safetensors
diffusion_pytorch_model.safetensors

where did it download these? as I already have them in another directory - and they are quite large to have "doubled up"

EDIT:
No matter, currently not supporting ML (there is a surprise - not blaming this community or its dev's btw)
