AI render enhancer

AI Render Enhancer: Make Your Architectural Renders Photoreal

Export a render or a viewport image from Lumion, Enscape, Twinmotion, V-Ray, D5 or SketchUp as a JPG or PNG, upload it, and ArchitecturesAI paints over it with more convincing materials, daylight, shadows, sky, planting and people. The walls, openings, camera and layout in your image are what the AI builds on. There is no scene to re-light, no material library to fix and no GPU to wait on. You get a new image back, not an updated model, and the AI can change small things, so check it before it goes to a client.

Flat grey and white real-time style render of a double-height office atrium with an upper gallery behind a glass balustrade, a straight concrete stair with a steel handrail, square columns, one empty white planter, glazed partitions on the left, a dark grey back wall and no people — Both images are AI-generated with our own image model; the "before" is made to look like a flat real-time engine render, not exported from Lumion, Enscape or Twinmotion. Edit prompt used: "Enhance this flat 3D render into a photorealistic architectural interior photograph: polished light concrete floor, warm oak treads on the staircase, clear glass with real reflections, bright natural daylight with soft realistic shadows, green plants and a small tree in the planter, and a few office workers walking and talking. Keep the exact space, staircase, gallery, columns, planter, glazed walls and camera angle." What followed it: the gallery, glass balustrade, straight stair and columns stayed in place, the floor became polished light concrete, the stair treads and risers turned oak, daylight now falls in with patches of sun, the planter got a small tree and leafy plants, and people now walk across the floor, down the stairs and behind the left glass. What did not: the glass reflections are only modest, and the stair's side stringer stayed grey concrete. Extra changes the AI made on its own: a second planter by the left wall, a potted plant on the stair, a desk and office chair behind the stair, greenery through the glass door at the top of the stair, a faint shadow figure on the wall of the left glazed room, and the dark back wall turned white. The new tree also hides most of the column behind the planter.

Why architectural renders look flat

Most renders that look "CG" share the same problems: even, shadowless light; materials that are a single flat colour or a tiled texture; glass with no reflection; a plain sky; an empty site with no planting; and no people to give the space scale. Real-time engines such as Lumion, Enscape, Twinmotion and D5 can fix all of that, but it takes time on lighting, material maps, asset placement and settings, plus a graphics card that can handle it. A V-Ray or Corona scene can get there too, with longer render times.

Early in a project, most of that effort goes into images that will be replaced next week. An AI render enhancer is a shortcut for those stages: you keep the geometry and the camera you already have and let the AI add the light, texture, landscape and life that make a picture read as a photograph.

How to enhance a render with ArchitecturesAI

Export the view you want as a JPG or PNG: a Lumion, Enscape, Twinmotion or D5 screenshot or still, a V-Ray or Corona frame, or a SketchUp scene exported with File > Export > 2D Graphic. About 1,600 pixels wide or more keeps thin details such as railings and mullions.
Click "Enhance your render". The Render Architecture tool opens with Residential and Modern selected. Sign in with Google or email.
Upload your render and pick the building type that fits: Interior or Office for an interior view, Exterior, Residential or Villa for a house, Commercial or Facade for a street front, 3D Model for a plain model view (25 types in total).
Pick the style that matches the design you already have, such as Modern, Contemporary, Minimalist, Scandinavian, Mediterranean or Traditional (25 styles in total). The tool asks the AI to render your building in that style, so a style far from your design pulls the result away from it.
Press Generate and download the result.
To steer one thing, such as people, planting, time of day or a material, open Custom Action or Edit Image on the result and describe the change in a sentence. Those actions work on the rendered result, not on your original upload. You can paste the prompts printed under each example there, but the examples on this page ran directly on an image model, not through this tool, and the tool runs different models, so your result will differ. Each change runs a new render and uses credits.

Enhance your render

Enhance or upscale: which one you need

These are two different jobs. Enhancing, in the sense of this page, repaints the image: it adds light, shadows, reflections, material texture, trees and people that were not in your render. Upscaling keeps the picture as it is and makes it larger and sharper, cleaning up noise and soft edges without adding anything new.

ArchitecturesAI has a separate Enhancement tool, and it is an upscaler. It takes an image with no prompt and enlarges it, with Noise Reduction, Detail Enhancement and Standard options. Free accounts get 2x; 3x and 4x are for paid accounts. It will make a flat render bigger and crisper, but it will not make it look photographic. To go from flat to photoreal, use the Render Architecture tool above; if you also need a larger file at the end, you can run the result through the Enhancement tool afterwards.

Low-resolution flat render of a white two-storey flat-roofed villa with a timber-clad upper box, full-height ground-floor glazing with a sofa inside, a rectangular pool with flat blue water, a grey paved terrace, grass and a plain grey sky — An AI-generated pair made with our own image model; the "before" imitates a quick, low-resolution export from a real-time renderer. Edit prompt used: "Enhance this flat 3D render into a photorealistic architectural photograph: crisp white render walls, warm natural timber cladding with visible grain, clear glass with sky reflections, transparent pool water with soft ripples and reflections, warm late-afternoon sunlight with long realistic shadows, a blue sky with a few clouds, olive trees and grasses around the terrace, and two sun loungers by the pool. Keep the exact building volumes, roof lines, window openings, pool shape and camera angle." What followed it: the volumes, the timber box, the window openings and the pool shape stayed the same, the walls are crisp white, the timber shows grain, the glass reflects the sky, the pool has ripples and reflections, and the warm low sun, long shadows, blue sky with clouds, olive trees on both sides, grasses and two sun loungers all appeared. What did not: the pool water reads darker and rippled rather than clearly transparent. Extra changes the AI made on its own: a hedge along the back of the lawn, a white garden wall at the far right, the black ground-floor window frames turned bronze, and trees reflected in the glazing.

Get more out of your render before you upload

The AI only sees the picture, so the input decides most of the output:

Turn off overlays. Hide grids, section planes, dimensions, axes, selection outlines, watermarks and UI panels before exporting.
Keep verticals straight. Two-point perspective reads like architectural photography; a tilted camera makes walls lean, and the enhanced image keeps the lean.
Give materials distinct colours. Even rough colours for glass, timber, render, stone and roof help the AI tell surfaces apart; an all-white clay model leaves more to guesswork.
Model what matters. If a mullion pattern, a balustrade or a roof edge is part of the design, it should be in the render. The AI fills empty areas with its own ideas.
Show the ground and the sky. A terrace, lawn or street tells the AI where the building sits; a model floating on a blank background gets an invented setting.
Ask for people and plants in words. Use Custom Action to say how many people, where, and what kind of planting, rather than placing low-quality assets in the scene.
Export large and leave a margin. Small images lose fine detail, and anything cut off by the frame stays cut off.

SketchUp-style shaded model export of a two-storey gable house with an attached one-storey garage wing on the left, flat grey siding with black edge lines, white-framed windows, a dark roof, a flat grey driveway, flat green ground and a light blue sky — Both images come from our own image model; the "before" is drawn like a SketchUp shaded view with edges, not exported from SketchUp. Edit prompt used: "Enhance this shaded 3D model export into a photorealistic architectural photograph at golden hour: real fiber-cement lap siding in warm grey, white window trim, dark asphalt shingle roof, warm low sunlight with long soft shadows, a lit window or two, a green lawn with shrubs and young trees along the front, and a soft golden sky. Keep the exact house shape, roof lines, garage wing, window and door positions, driveway and camera angle." What followed it: the house shape, roof lines, garage wing, window and door positions and the driveway stayed where they were, and the lap siding (warm grey only on the shaded side), white trim, dark shingle roof, low warm sun, golden sky, lawn, shrubs and two young trees all appeared. What did not: the prompt asked for a lit window or two, but every window glows. Extra changes the AI made on its own: the faint garage door outline became a clear panel garage door, a lamp shows inside the lower middle window, the sunlit front gable and the garage end wall read tan-beige rather than grey, and fields and trees appear in the background.

Photorealistic golden-hour photo of the same house with lap siding that reads grey in shade and tan in the sun, white trim, a dark shingle roof, all windows lit, a panel garage door, a lawn with shrubs and two young trees, fields and trees behind and a golden sky — Both images come from our own image model; the "before" is drawn like a SketchUp shaded view with edges, not exported from SketchUp.

What the AI changes, and what to check

The AI keeps the camera, the massing and most openings, but it is not reading your model. As the captions above show, it adds things you did not ask for: extra planters, furniture, garden walls, a garage door, fields in the background. It can also miss part of an instruction, such as lighting every window when you asked for one or two. Two runs of the same image will not match exactly.

So treat the result as a design image, not a construction document. Compare window counts, mullion patterns, rail heights and roof edges with your drawings before the image goes out, and run it again or edit it if something has drifted. When the design is fixed and you need exact materials, repeatable views, animation or a walkthrough, finish the job in your renderer.

Who uses an AI render enhancer

Architects who need a convincing image for a client meeting or competition board before the scene is fully lit and textured.
Students who work in SketchUp or a real-time engine on a laptop and want a photographic image for a review.
Visualisers who want a quick mood or lighting study from a draft render before committing to a long final render.
Developers and agents who have a plain model view and want a marketing-style image of the same building.

Frequently asked questions

What is an AI render enhancer?

It is a tool that takes a finished or draft architectural render and repaints it to look more like a photograph: more realistic materials, light and shadows, reflections, sky, planting and people. On ArchitecturesAI you upload the render to the Render Architecture tool, pick a building type and a style, and download the result.

Will it change my design?

It builds on your design, but it does not copy it exactly. The camera, massing, openings and layout usually stay, as the three examples show. The AI can add or redraw small things, such as furniture, planters, a garage door or background trees, and the style you pick can pull details toward that style. Check the result against your drawings and run it again if a part drifts.

Which rendering software does it work with?

Any that can save an image. Lumion, Enscape, Twinmotion, D5, V-Ray, Corona and SketchUp exports all work, as do screenshots of a viewport. The tool only sees the JPG or PNG you upload, so the software and version make no difference, and nothing is installed or linked to your model.

Can it add people and vegetation?

Yes. The examples on this page added office workers, a tree in a planter, olive trees, grasses, shrubs and lawns. In the tool, run Generate first, then use Custom Action or Edit Image on the result and say what you want, for example "add a few people walking and two olive trees by the terrace". The AI decides their exact look and placement.

What is the difference between enhancing and upscaling?

Enhancing repaints the image with new light, texture, planting and people. Upscaling only makes the existing image larger and sharper. The site's Enhancement tool is an upscaler (2x on free accounts, 3x and 4x on paid ones); the Render Architecture tool is the one that makes a render look photographic.

Does it give me a higher resolution file?

Not by itself. The Render Architecture tool returns a new image; if you need it larger, run that result through the Enhancement tool, which upscales it. Starting from a large, clean export also helps.

How is this different from sketch to render?

Sketch to render starts from a hand sketch, line drawing or massing model and invents most of the materials and setting. A render enhancer starts from an image that already has your materials, camera and lighting roughly set, and makes it look more real. If you only have a sketch, use the sketch to render AI page instead.

Is it free to try?

Yes. After you sign in, a new account gets 2 free renders with a watermark. In India this site does not include free renders. Paid weekly, monthly and yearly plans are listed on the pricing page.
