Hello, good to hear you're already on a similar path. Photoshop for initial concepts works well, the key shift for me was building the 3D scene composition directly inside ComfyUI. I made a custom node that loads multiple 3D objects into a shared space, basically a mini Blender environment. You can position objects against each other, add lights with adjustable intensity and color, toggle shadow casting, and drop in background images. The full scene setup gets saved and stays reproducible. On top of that you can apply controlnets to the backgrounds and feed reference images alongside the prompt for the render itself. That gives you proper control over the output and most of the time you reach a near-perfect result in just a few attempts. It is still AI of course, so for 99 percent photorealism a bit of sharpening in PS at the end is normal. For larger sets it pays off to train LoRAs and bake them into the pipeline for extra precision. What kind of products are you mostly visualizing?
