Here is another example of me adding a window here - Please try our Touch Up Studio

Hey Stephanie we looked at your requests and learnt that -

You were trying to "move windows to the left wall," the model silently ignores it (because we trained the model to preserve structures and windows). Currently Moving windows isn't supported - the structural layout is preserved.

Try in-painting "Touch Up Studio" to modify specific areas of the space you are trying to modify -

Hey Stephanie, can you share what kind of renders are you trying to generate?

Maybe we can help you with it...?
