LayerDiffuse SD15 brings 4 new models:

Generate FG

Use the apply node the same way as before.

Generate FG + Blended given BG

Need batch size = 2N.

Generate BG + Blended given FG

Need batch size = 2N.

Generate BG + FG + Blended together

Need batch size = 3N.

Notes:

• Dropdown options in previous nodes are updated. You will need to re-select the config for your previous workflows
• Unlike forge impl, which does cond concat for fg/bg/blended, in ComfyUI impl, the cond passed to layer diffusion node directly overwrites the global cond.
• LayerDiffuseDecode (Split) is added to decode RGBA every N images. It serves the purpose to only decode FG images in a batch.
