Realistic Renders Start with a Clear Client Brief

A strong 3D render starts with a clear client brief.
Take time to learn how your client lives each day.
When you meet with them, focus your questions on a few key points.
- Ask about the architecture style they like.
- Ask which rooms they use most each day.
- Ask what matters most, such as a home office, a big kitchen, or space for kids.
Use these answers to build a short written brief you can follow.
Keep in mind that different clients need different layouts.
- A young family may want open living spaces and easy access to the garden.
- A retired couple may want a comfortable kitchen and quiet bedroom suite.
- A remote worker may need a dedicated, quiet home office.
If your client loves to entertain, show a large living room with a big table and wide openings to the terrace.
If they want privacy, focus on quiet spaces like the master suite or a snug TV room.
Create a simple questionnaire you can review in meetings or send by email.
Ask clients to share a few inspiration images so you can see the style, ideas, and mood they like.
Step by Step Guide: How To Create 3D Renders
Step 1: Draw Complete Plans

With Cedreo and similar design tools, the 3D images are generated automatically from your 2D plan.
So if the 2D plan is incomplete, the 3D model will also lack details.
Wrong window placement, bad elevations, or a flat lot that should be sloped all make it harder for your client to visualize the design.
That’s why a realistic render always starts with detailed and accurate plans.
- Draw all exterior and interior walls and partitions, either from a blank page or by tracing over an imported plan.
- Check line weight, edges, and main geometry so the basics of your design stay clean and easy to read.
- Move walls, resize the whole house, or add a lower or upper level with a single click when you need changes.
- Place doors and windows with the right size, style, and color by choosing from Cedreo’s library of more than 1,500 openings.
TIME-SAVING TIP! Apply the same settings to all doors and windows at once to keep a consistent look and save time.
- Add the roof, set its pitch, and create valleys and dormers based on the rooms under the roof.
- Model the terrain using the site plan and adjust elevation points or lines so slopes and levels match real life.
- Place the house on the lot, add a compass for orientation, and draw driveways, terraces, parking areas, and retaining walls.
Step 2: Add Materials and Finishes

The look of your 3D image depends heavily on the textures you choose.
Small details like wood grain, tile joints, and reflections on shiny surfaces make a big difference in a realistic render.
Use materials to support the story you want to tell in each room.
- Mix a variety of materials on facades and inside rooms to add depth and increase perceived quality.
- Use Cedreo’s catalog of more than 2,500 interior and exterior finishes and click to add materials to walls, floors, and other surfaces.
- Use the zone tool to create bands, frames, or accent areas on facades, then change the material in that zone for contrast.
- Choose a roof color that matches local style and industry standards, such as dark slate or warm clay tiles.
- Set tile size or define plank flooring direction based on room size and window placement so patterns feel natural.
- Use invisible walls to split one room into two zones when you need different floor finishes.
For faster design decisions, test several variants of the same project by changing only the materials so clients can compare two realistic render options side by side.
Step 3: Furnish Interior and Exterior

Once the volumes are drawn, the layout and décor bring the scene to life.
Furniture, lighting, and accessories show how your client will use each space day to day.
- The Cedreo advantage: Cedreo gives you a large library of more than 6,000 high-quality furniture and décor objects you can customize in size, color, and texture.
- You can also use ready-made furniture packs to speed-up your workflow by furnishing a living room, bedroom, or kitchen in just a few clicks.
- Pay close attention to light fixtures because they guide the eye, add reflections, create shadows, and highlight textures in your environment.
- A common mistake is to skip interior light sources and rely only on daylight.
- A render without lighting often looks flat, and you lose the ability to enhance key details in the scene.
- Outside, think about the house in its full environment, not as an object alone.
- Use planters and low hedges in the foreground.
- Place lawn, garden furniture, and planting beds in the middle ground.
- Add trees and simple building shapes in the background.
Step 4: Choose the Right Camera Angles

Treat each render like a photograph.
Use an eye level camera so the space feels natural and easy to read.
Think about vanishing points and main sight lines so the composition feels balanced.
Pick views that match the priorities your client shared in the brief.
- If they care about social time, show the kitchen island, dining table, and living area in one view.
- If natural light matters most, place the camera in the living room and open the view to the terrace and garden.
- If storage is a concern, focus on built-in cabinets, closets, and smart niches.
By matching your views to client needs, you show more than a house or apartment.
You show your client that you listened and understood how they want to live.
CEDREO TIP! Save each camera viewpoint in Cedreo so you can reuse the same angle while you test different materials or layouts.
Step 5: Set Natural Light

Natural light gives your 3D model its final touch of realism.
Adjust the sun orientation and height so shadows fall in a believable way.
- Think about the main light source in each view and how it will cast shadows on walls, floors, and furniture.
- Test several times of day, such as soft morning light, warm evening light, and a night view.
- Try different seasons because a low winter sun does not behave like a strong summer sun.
Always check that shadows don’t end up hiding key parts of the building.
Remember that a small change in sun position can make a terrace, façade, or main room stand out.
Step 6: Choose the Right Background

Even the best house model will look fake if it sits on a white void.
The background gives your render context and makes the scene feel like real life.
Here are two ways to add realistic backgrounds in “Environment Choice” option under the HD Visual tab.
- In Cedreo, you can use standard landscapes such as city, countryside, mountains, or coast.
- You can also import a real photo of the site and place the house in its true surroundings.
This helps clients see their future home with the real road, trees, and neighbors they already know.
Step 7: Generate and Share 3D Renders

The last step is to turn your 3D model into photorealistic images.
Cedreo lets you start the render from the HD Visual step and get the result in just a few minutes.
The Cedreo Advantage: Because Cedreo runs online, you don’t need a powerful computer to create high quality renders.
You can see changes in the 3D model in real time rendering mode as you work.
You can even keep working on other designs while software creates the final renders.
- Use HD format for quick previews you share by email or during a client meeting.
- Use Full HD format for brochures, sales documents, and product design proposals.
Once your images are ready, download them or add them to your presentation documents.
Important! If you change the project, remember that the 3D model updates but the rendered image does not.
You will need to generate a new realistic render so it reflects your latest design choices.
