Post your best prompts.  Here's mine.

 

Make this 3D CAD model look photo-realistic.  Use sun and shadows in the morning. Place a cedar privacy fence behind this shed.  Behind the privacy fence show some new homes in this newer subdivision.  Add some light landscaping and maybe a mulch bed with shrubs or flowers.  Place a lone large mature Douglas Fir behind but near the privacy fence.  Do not modify the structure.  Keep the original colors of the model.

My camera view placed into ChatGPT..  just playing.  I told it to place in the mountains (because that is where it's being built in NC), make landscape more realistic, add snow on the second draft.  You guys didn't know I invented a snow proof flag and pole, did ya!

 

@para-CAD

I've been meaning to get a second shed, thanks for the reminder.

1st image = Chief Standard view, all out of the box no PBR.

Gemini (free, no account) 

Prompt = "Increase photorealism of this image. Improve lighting, global illumination, reflections, shadows, and material texture resolution. Preserve the exact architecture, materials, proportions, windows, doors, and camera perspective. Do not modify the design in any way—only enhance realism and render quality. "

Chat GPT = make above rendering a winter scene but do not alter architecture or materials.

Michael....I was hoping you'd share your renders from your other thread.  

I hope we can build some great prompts to get high quality renders in seconds.

 

ChatGPT Images 2.0 just dropped.  

People are saying it has dethroned Nano Banana (Google Gemini)

We shall see.

 

I had some success with Grok, initially, but now it cranks out completely blurry images like I'm showing a home from Witness Protection.

 A client emailed me and wondered what direction I was running with his house, since the ROW and easements were ridiculous on a small city street.  The model is a WIP, but I did a quick camera view, and a screen grab at street level, and had ChatGPT merge the two, and remove trees.  First pass was enough to convey the direction.

Well I've used chat gpt to change exterior wall materials and colors and it seemed to work fine. I even deleted a curved stairwell in one of my plan files and asked AI to make a better curved staircase and it worked nicely. Today I put it to the test and I wouldn't say it is to scale but it did a great job when I told it to merge these two screen shots of the floor plan my client wants. I searched everywhere but failed to find the web link. AI couldn't even find it with all the info put in.

Here is a project I am involved in currently.  It's in very early development but, I wondered tonight what Google Gemini / Nano Banana would output based on my original image.  Nothing special.

A.I. Prompt

 

Turn this rendered image into a photo realistic rendering. Do not change the structure. Keep integrity and colors of the original structure. Siding is suppose to be board and batten. Add a gravel driveway going up to the garage doors. Add some landscaping and make it a late afternoon sunny scene.

I disagree.  

 

If I were a client and looking at your Chief standard render I would not want to live in that and I would already be starting to think that maybe I chose the wrong draftsman/designer/architect.

 

With Gemini render, I personally would love to live in that myself.  

 

I can see myself smoking a cigar on the front porch and enjoying the scenery.

 

What you did in, I'm guessing 20 seconds in Gemini?... Would not be possible in Chief and even with the help of TwinMotion would take hours and hours and never come close.

 

Nice job!

I tried doing that last pic a few years and it looked pretty good. I took a google maps screenshot of the lot and use it as a backdrop in CA. You know, before AI was coming out.
