Is Rendair worth it? 8 AI rendering challenges tested by Adrian Mazur

Adrian Mazur is a practicing architect who reviews AI tools on his channel. After an earlier video where free AI models struggled with specific requests, he sets Rendair eight practical challenges drawn from his own projects and scores each one. It is a useful watch if you want to see where the tool holds up and where it needs a second pass, on real houses rather than demo images.

What you'll see

1. He renders a simple exterior 3D model in the app then called 3D base to render, keeping image strength moderate and creativity low, and compares it with the free models he tested before.
2. He tries a more complex house, then a front view where the garage door turned into glazing. A negative prompt fixes it, and a follow-up asks for cobblestones to the entrance.
3. He renders an interior kitchen and living space from a 3D model view.
4. In Chat he describes an early-stage residential building from text, then asks for an entrance door between the two volumes.
5. In Chat he removes clutter from photos of a finished project for his portfolio, then upscales to 4K.
6. In Elevation to Render he turns a colored elevation into a render, lowers creativity, and uses Select and Modify to add a road, neighbors and greenery.
7. In Chat he furnishes a photo of an empty room.
8. He furnishes a photo of a construction site, then uses Select and Modify to paint walls white and Remove Objects to clear a pillar, cables and unfinished floor.
9. In Sketch to Render he turns a white line sketch into a render after raising image strength and lowering creativity.

Takeaways

• He found the portfolio photo cleanup better than his own Photoshop work, especially the shadows. He noticed a slight quality loss and fixed it with an upscale.
• He points out the misses: roof eaves on one render, a terrain that ignored the hillside, a camera angle that shifted, and a prompt line about white walls that was skipped until he edited it.
• He recommends structuring prompts around goal, changes, style, context, what to keep or remove, and level of detail.
• He found a negative prompt was the fix when the AI added elements that were not in the model.
• His verdict is that it has limits like any AI, but saves real time on day-to-day tasks, especially early concept work.

Try it yourself

Start with 3D Model to Render or Elevation to Render, use Remove Objects and Select and Modify for corrections, and try Chat for photo cleanup.
