Hi, do you have any suggestions if small foreground image remains grey(failed to synthesize)?

[bo-zhang-cs]

If you use ControlCom, downsampling in the autoencoder and U-Net of the diffusion model can result in synthesis failure when the input bounding box is too small. To mitigate this, I recommend directly enlarging the bounding box or enlarging it by cropping and zooming in the background region, which may help prevent such issues.
