Was trying to get a character to hide behind curtains but it wasn't really working so I quickly scrapped this together.
Prompt: curtains, hiding, curtain grab, nude, shadow
May help: covering (insert body part here), see-through, silhouette
Mainly trained with images of curtains covering nude bodies. If you try to use a character's clothes or outfit lora it may keep the curtain from covering the whole body. Without the nude tag or proper clothing tags curtains may become clothes.
You can also try to attempt to try using objects similar to curtains such has bed sheets or towels.
Have fun!
