← ComfyTV Mask

Out-bridge: extract MASK tensor from COMFYTV_IMAGE (often PNG with alpha). No ▶ Run — loads on Queue.

What this node does

ComfyTV Cutout and alpha PNGs output COMFYTV_IMAGE. ComfyUI inpaint / ControlNet need MASK. This node inverts alpha to mask (same as _load_image_tensor logic), matching ComfyUI conventions.

Shares URL input with ← ComfyTV Image: one branch RGB, one branch mask.

When to use it

• ComfyTV Cutout → native Inpaint
• ComfyTV edit → ControlNet Inpaint
• Split one COMFYTV_IMAGE: ← Image + ← Mask

How it works

• Normal node, no Run.
• With alpha: mask = 1.0 - alpha; without: zeros.
• Output [1,H,W] float.

FAQ

Q: Wrong mask after Cutout?
A: Ensure PNG has alpha channel.

Q: vs Inpaint Stage brush?
A: Inpaint Stage masks inside ComfyTV; this exports mask to native inpaint.
