Ref img for background

[mischaschaub]

Would it be possible to have a ref img for the background? This certainly would enhance continuity for a scene. At the moment I create a lot of stills and arrange these as keyframes in the great app dough from Banodoco. Works pretty.

At present, I don't have a good idea to implement this operation, but can it be achieved by cutting out the image?

@Z-YuPeng can we build some relationship between the background to the noised img, for example, during the denoising process, a model can identify the background tokens?
