Hey @Issie28795101fjta
Thank you for sharing your prompt and screenshot.
Prompt provided:
Add the pictures and the shelves—as seen in the SketchUp image—to the photorealistic render; do not change the perspective—it must be isometric, just like the reference.
Prompt suggestion
use reference image, keep the details of the image, add the shelves according to the sketch, keep the isometric layout
Honestly I am not sure that is going to work. However, adding positive enforcing prompts will often give you an output.
