Frequently Asked Questions

Fenestra is a professional AI rendering and visualisation platform built for architects, interior designers, and real estate professionals. It combines image generation, real-time sketching, image editing, upscaling, and AI video animation into one workspace, with purpose-built tools for architectural workflows.

Fenestra is built for architects, interior designers, landscape architects, real estate agents, visualisation studios, and architecture students. It supports practices of every size, from solo designers on the Individual plan to enterprise studios on Team and Enterprise plans.

You can create photorealistic exterior and interior renders, sketch-to-render transformations, virtual staging for empty rooms, multi-angle views from a single image, 4K and 8K upscaled images for client delivery, and cinematic animated walkthroughs from a still image.

Fenestra includes curated access to leading models for architecture and design including Flux Klein, Flux Kontext Pro, Dev, and Max, Nano Banana (Gemini 2.5 Flash), Seedream 4.0, Qwen Image Edit, Runway Gen-4, and custom Fenestra solutions.

Most AI tools are built for everyone, which means they are optimised for no one. Fenestra is built specifically for architectural and interior design visualisation, with workflows for CAD, sketches, 3D models, and virtual staging that general-purpose tools do not support.

Create a project from the Fenestra dashboard, choose a tool (Image, Edit, Realtime, Enhance, or Video), upload a sketch, photo, or 3D model if needed, then write a prompt and click generate. Most users produce their first render within five minutes.

No. Fenestra works from sketches, reference photos, prompts, and uploaded 3D models. You do not need prior experience with Blender, Lumion, V-Ray, or any traditional rendering software to produce professional results.

Image is the most common starting point because it generates renders directly from a prompt, a sketch, or a reference photo. Use Edit if you already have a rendering you want to refine, or Realtime if you want to draw and watch AI render live as you sketch.

You can upload JPG and PNG images for sketches, references, and renders, plus 3D model formats including GLB, GLTF, OBJ, and FBX for editing and rendering directly from geometry inside Fenestra Studio.

Most users go from signup to their first generated render in under five minutes. The four steps are create a project, choose a tool, upload an image or write a prompt, then click generate.

Specific prompts produce better results. Describe materials, time of day, lighting, location, and style. For example, photorealistic timber and glass skyscraper in New York City, early morning, long shadows is more effective than just modern building.

Fenestra Studio has six main areas: the top tool navigation bar to switch between Image, Edit, Realtime, Enhance, and Video; the session sidebar on the left; the studio canvas; the prompt bar at the bottom; the details sidebar on the right; and the persistent bottom toolbar for compare, download, and view controls.

Yes. Switching between Image, Edit, Realtime, Enhance, and Video does not lose your work. Everything is stored in your session and you can return to any previous canvas via the session sidebar on the left.

Open the generations panel from the bottom right toolbar to see every output from your current project. Click any generation to view its prompt, model, mode, aspect ratio, and resolution, or to copy the prompt and send the image to another tool.

The right sidebar is context sensitive. When an output is selected it shows the generation record with prompt, model, mode, and resolution. When you work with a 3D model in Edit or Realtime it switches to 3D Controls for camera, lighting, and environment settings.

Fenestra Studio includes six tools: Image for prompt and sketch to render, Edit for refining and transforming renders, Realtime for live sketch to render, Enhance for upscaling to 8K, Video for cinematic camera moves, and 3D Models for rendering directly from geometry.

Use Edit for finished sketch to render output because it transforms a sketch using the context of the underlying drawing. Use Realtime for live ideation where you want to see a render appear as you draw on the canvas.

Yes. Fenestra supports GLB, GLTF, OBJ, and FBX 3D files. You can import a model into Edit or Realtime to render directly from geometry with AI generated materials, lighting, and environment, with full camera control.

Open the Video tool, set a start frame, optionally set an end frame, choose a duration, and pick a camera movement such as pan, dolly, orbit, or a preset built for architectural visualisation. The tool animates the still into a cinematic video clip.

Image generates renders from prompts, sketches, or reference photos. Edit refines or transforms an existing image or 3D model with masking, inpainting, expand, and replace tools. Realtime renders your sketch live on the canvas as you draw.

Expand changes the aspect ratio of an image by extending the canvas. You can take a 1:1 square and extend it to 16:9, 3:2, 4:3, or other ratios. Fenestra fills the new area using the context of the existing image so the scene continues naturally beyond the original edges.

Edit area uses the context of the underlying image to make targeted changes inside a masked region, ideal for adjusting materials or refining details. Replace area overwrites the masked region entirely with new content from your prompt, with no context from the original.

Camera control lets you generate new camera angles from a single input image using an orbit widget. You can rotate horizontally, raise or lower the angle, and adjust zoom to create alternative views without uploading or building a 3D model.

Yes. The Edit tools work on any image including uploaded photos, scanned sketches, previous Fenestra generations, and references from other software. Use Edit for virtual staging, material changes, sky and weather edits, and object removal or replacement.

Fenestra supports virtual staging, multiple angles from a single image, sketch to render, CAD to render, 3D model to render, image enhance and upscale to 8K, cinematic video animation, and style transfer for consistent visualisations across a project.

Yes. Fenestra has dedicated workflows for converting CAD drawings, Revit models, Rhino 3D files, and SketchUp scenes into photorealistic renders. Export your model as GLB, GLTF, OBJ, or FBX and import it into Edit or Realtime to render directly from geometry.

Upload a photo of an empty interior and a second reference image of the furniture you want to place, then prompt Fenestra to add the furniture. The AI organises and lights the new pieces inside the original space and produces a staged photo ready for real estate listings or design presentations.

Yes. You can upload photos of specific furniture pieces, moodboards, or product shots as reference images. Fenestra uses the reference furniture to place real, identifiable pieces inside the empty room rather than generic generated furniture.

Nano Banana 2 (Gemini 2.5 Flash) is a strong default for virtual staging because it preserves the original room geometry while accurately placing reference furniture. For higher fidelity output, switch to Flux Kontext Max or Seedream 4.0.

Yes. Fenestra produces 1K, 2K, 4K, and 8K virtual staging output suitable for MLS listings, property marketing, and high-resolution print. The Enhance tool can upscale staged images further for premium real estate photography.

Open Edit, upload or select an image, click the Camera icon in the Edit toolbar, then use the orbit widget to rotate, raise, lower, or zoom the camera. Click Edit to generate the new angle. No prompt is needed in most cases because the camera position guides the output.

No. Fenestra generates new camera angles directly from a single 2D image using AI. A 3D model is not required. This makes multi-angle renders accessible from any uploaded photo, sketch, or previous generation.

Small camera adjustments produce the most consistent results. Fenestra uses the original image as context, so subjects, materials, and lighting carry across angles. Larger orbit angles may introduce more interpretation, useful for exploration but less precise than a true 3D render.

Open Account Settings, click Plans and Pricing, then select Cancel. You retain access to your plan until the end of your current billing period. After that, your account reverts to the Free plan and your assets and generations are preserved.

Subscriptions renew automatically on the same date each month, or each year for annual plans. Your renewal date is visible in account billing. You will receive an email receipt from payment provider Lemon Squeezy after each successful payment.

No. Cancelling drops your plan back to Free at the end of the current billing period, but your projects, generations, and uploaded assets are preserved. You can resubscribe later and pick up where you left off.

Every generation in Fenestra consumes credits from your plan's monthly allowance. The exact cost depends on the model and task and is always shown in the prompt bar before you generate, so there are no surprises. Credits refill at the start of each billing cycle.

Each model has its own credit cost. Some models cost as little as 1 credit per generation, while higher-fidelity models can cost 10 or more credits per render. Image generations, edits, enhancements, and video animations each have their own per-model pricing.

No. Credits reset at the start of each monthly billing cycle and do not roll over. To keep a larger balance available, upgrade to a higher plan with a bigger monthly credit allowance.

The Individual plan includes 200 credits per month, Pro includes 1,000, Studio includes 2,000 to 8,000 depending on tier, and Team includes 5,000 to 10,000 in a shared pool. Enterprise plans have custom credit allowances.
