I have had a couple of issues with Muse failing to generate when using an input image. What are the criteria for an input image?
Hi @Makit3D! Is it giving any kind of error in console? I just tested and it appears to be working fine, although the strength setting does not seem to have as significant of an effect as expected. We are looking into the strength now.
I tested with 128, 512 and 768px inputs in PNG format and they were correctly resized automatically. The model takes 512x512 inputs.
I don’t remember any errors other than the tool stating it failed to generate when using an imported image. I’ll try again tomorrow to see what, if any, errors pop up.
I have met same problem. My error is
Failed to download because HTTP/1.1 400 Bad Request

Input image was this. I checked if it is possible to generate a planet texture via Muse.
Thanks for the info 
we will be making changes to the image input to account for all resolutions. For the time being, you can crop+resize images to bypass the error. 512x512 is optimal and you can upscale the output afterwards, although we currently only support upscale to 2k and 1:1 aspect ratio. We are still experimenting with larger upscale sizes and different aspect ratios.
