AI architectural rendering tool tutorial: every app by Salmaan Mohamed

Salmaan Mohamed is an architect and illustrator who reviews tools for architects. This is a structured walkthrough of Rendair's create and edit tools, from sign-up to upscaling, with prompting advice along the way. At the end he renders SketchUp models and sketches his Instagram followers sent him, which shows how the tools handle inputs he didn't prepare himself.

What you'll see

1. Signing up and finding the tool tabs.
2. Text to Render for a modern multi-story shopping complex, with prompt keywords picked by category, creativity, reference image, aspect ratio and number of images set.
3. Elevation to Render on a clean elevation drawing, keeping creativity at 50 or lower so the outlines hold, then refining the prompt for a better result.
4. Sketch to Render on an abstract living and dining room sketch at creativity 75, then on a cleaner exterior sketch for comparison.
5. 3D Model to Render on a resort model exported from SketchUp as a JPEG, with lower creativity.
6. Image to Render to change the mood of an existing image, turning it into a rainy scene while keeping shape and color strength high.
7. Select and Modify with an automatic area selection to turn roads into a stone walkway.
8. Remove Objects, which detects the elements in the image for you.
9. Inserting a human silhouette and blending it in with the older insert and modify tool.
10. Drawing a rough building outline straight onto a Google Earth street view of an empty site with sketch in context.
11. Upscale to 4K with the option to fix people.
12. Follower models: a bathroom, a shop elevation, a stone facade, an office interior, a villa sketch and a cat drawing.

Takeaways

• He found the text-to-render images close to photographs, without the rough edges he often sees in AI images.
• For elevations, he recommends clean, not overly detailed line drawings and a high-quality upload. He found textures a bit heavy at first, fixed with prompt tweaks.
• He stresses that the output depends heavily on the input. A cleaner sketch gave a clearly better result than an abstract one.
• The resort render had problems in the landscape on one side, which he says can be fixed with the edit tools.
• Some follower inputs needed prep in Photoshop first, such as filling empty edges or converting a drawing to black and white.

Try it yourself

Pick the app that matches your input: Sketch to Render, Elevation to Render or 3D Model to Render. Fix details with Select and Modify or Remove Objects, then use Upscale for the final image.
