Does ChatGPT already have a function where I can upload a photo (standard jpg for example) and some 3D model and it will place this 3D model on the photo?
I have the same question , but Unfortunately no one has answer ..
You can use ChatGPT Images to make a visual mockup from uploaded images: https://help.openai.com/en/articles/11084440. For a 3D object, a rendered image can be a useful reference, but that isn’t the same as importing and positioning an editable 3D model.
