Practical Tips To Improve Your 3D Renderings
If you’re looking to improve your 3D rendering skills and create stunning visualizations, you’ve come to the right place. In this guide, we’ll provide you with nine practical 3D rendering tips that will help you enhance your workflow, improve your output quality, and save you time and frustration. Whether you’re a seasoned professional or just starting in the world of 3D design, these tips will provide you with valuable insights and techniques to take your renderings to the next level. So, let’s get started with these essential 3D rendering tips!
Mastering Photometric Lighting: Pro Tips for Realistic Illumination
Lighting is absolutely crucial when it comes to creating realistic renders, and when not done correctly, the quality of the image suffers massively. To create a lighting setup in 3D, you first need to work on positions, shapes, color temperatures, and intensities, and then try to recreate these in 3D in a way that matches the real world. It’s also worth paying close attention to shadows, they play an important role when it comes to photorealism and help to add a contrasting effect. There are a few tools available that can help you out when it comes to lighting, such as interactive rendering and light mix, available in programs like Corona and Vray, which provide instant feedback to help you experiment and see which lighting setups look the best.
Round Your Edges: Tips For Smooth And Polished 3D Renders
A good initial tip for creating renderings is to round your edges. Even in decent looking renders, geometry with sharp edges is often used, which doesn’t actually exist in real life and therefore should not exist when creating realistic renders. Rounded edges improve how light and reflections affect an object, resulting in smoother, more natural highlights.
There are few different methods to achieve rounded edges, with the most common one being the chamfer modifier in 3Ds Max and another being to add supporting edges and a turbosmooth modifier. This technique takes more time and adds additional geometry, but it can result in a more realistic look. Last but not least, another option is to use a material to round the edges as opposed to geometry which involves adding an edge texture such as CoronaRoundEdges or VrayEdgesTex to a material’s bump slot.
Use Surface Imperfections: Adding Realism to Your 3D Renderings
No surface is 100% perfect and clean, and this must be considered in the 3d world if you are looking to achieve high levels of realism. When looking at a real world surface, there’s always going to be some level of dust, scratches, dirt or other imperfections, no matter how clean or new it is. With this in mind, adding these sorts of imperfections to your scene can increase its realism in the context.
This can be done by making adjustments to the glossiness, which closely mimics reality by altering the sharpness of reflections throughout the material, and despite being very subtle, it has a nice impact on the realism of a particular scene. Another way to introduce imperfections to a material is by simulating edge wear (where an object’s edges show greater wear than its flat surfaces), which can be done using a layered material and a combination of imperfections and edge textures (such as CoronaRoundEdges or VrayEdgesTex).
With this in mind, remember also not to go overboard, use this in a subtle way – remember that the goal here is to improve realism, and not to make surfaces look dirty, worn out or grubby.
Capture Realism with Camera Angles: Essential Tips for Quality Renders
Similar to capturing a photo from the perfect angle, setting up the optimal viewing angle for your architectural renders can have a significant impact on the quality of the final result. Here are some quick tips that can make a notable difference in your renderings:
Purpose and Storytelling: Make sure that the angle aligns with the purpose/focus on the rendering. For example if there’s a particular selling point of a property that’s important for your client, make sure to choose an angle that showcases this in the best possible light.
- Experiment with Different Angles – It’s always a smart idea to test out lots of different angles for your project and provide your clients with a wide range to choose from.
- Composition – Techniques such as the rule of thirds and leading lines can help create visually pleasing images.
- Focal Length – Test out different focal lengths for desired visual effects.
- Lighting – Different Lighting Setups can work well with different angles, so this is something you can experiment with.
Creating Atmosphere in 3D Renders – Pro Techniques for Immersive Scenes
Adding atmosphere to 3d rendering definitely makes a difference when it comes to levels of realism and adds a layer of depth, but it’s important to be subtle to make sure that it doesn’t look out of place within the context of the image. In terms of tools to help add atmospheric fog, you can either use a volume material such as CoronaVolumeMtl or the z-depth render element, both of which will help add a layer of depth to your images.
Asides from tools, creating atmosphere in 3D renders involves using lighting, textures, composition, environmental elements, color and post-processing techniques to enhance the mood and ambiance of the scene. Consider the intensity, color, and direction of light and be sure to choose textures and materials that complement the atmosphere you’re looking to create. Rough and weathered textures can help to create a vintage/aged feel whilst glossy materials help to create a futuristic and sleek feel.
For composition, using framing, depth of field and focal length will make a big difference in creating atmosphere, and the arrangement of certain elements and objects can have a subtle impact on the overall feel/atmosphere of an image. Environmental elements can also make a big difference, with fog, rain, mist helping to create a moody atmosphere.
Lastly, it pays to carefully choose the color palette, selecting colors alight with the mood you want to convey. Warmer colors can help to create a cozy and welcoming feel, whilst cooler colors add a certain feel of calmness to an image.
Lens Effects in 3D Rendering: Adding Depth and Realism to Your Renders
Using lens effects in 3D rendering can add a touch of realism and visual interest to your scenes and there are few important rules to follow. Firstly, carefully choose the appropriate lens effect, whether it’s Depth of Field (DOF), bokeh, lens flare, or vignetting, as each can uniquely impact the image. It’s crucial to adjust your camera settings to align with the chosen lens effect, such as tweaking the focus plane and blur to achieve the desired depth of field. Additionally, it’s important to note that some lens effects that may have a negative impact on real-life photos, such as bloom and glare, can actually enhance the realism of a render when used. These effects can add a subtle touch to your image, elevating its overall aesthetic appeal.
Another option is to add lens effect in the post production phase, which can be done in image editing software to add filters and use other techniques to adjust the lens effect. As with many of the other points on this list, experimenting is something that makes a difference, and testing out different things on your lens effect such as intensity, color and size will allow for a greater chance of achieving the look you’re aiming for.
Scaling Objects Correctly: Tips for Achieving Proportional 3D Renders
As mentioned in the common mistakes section, one of the most obvious ways that a 3d render isn’t real is when the size of certain objects and furniture looks off, and it’s important that these match their real world counterparts accurately, so it’s important to double check that these elements match up when you import a model. The scaling of certain textures also plays a role, so you need to make sure that the orientation of a texture is correct and not repeated or tiled. Also, make sure object UV’s and material tiling are an accurate representation of the real-world material’s scale, and the texture orientation is correct.
Blend Photos
One great way of increasing the levels of photorealism of a 3d rendering is to blend it in with a real life photo. There are a couple of ways that this can be done depending on the type of project. For aerial renderings, getting drone photos of the surrounding area and blending these in with the 3D Rendering can look fantastic, and when done well, you won’t be able to tell the rendered parts apart from the photo. This can also be done for eye level exterior shots – once selecting the angle of the exterior shot you’re looking to render, you can take photos of the surrounding area which can once again be blended with the image. Last but not least, for 3D interior renderings, having background photos of what is shown through windows can add a nice touch of photorealism to an image.
Despite all of this, it’s important that high quality photos are taken and it’s recommended to hire a professional for the best results. If the photo is of poor quality then the viewer will be drawn to this and the overall look of the image will be lacking.

Details
When aiming for a high-quality 3D rendering, meticulous attention to detail is paramount. Every small element holds significance in achieving realism. As previously mentioned, it’s crucial to ensure that certain elements in the render reflect real-world imperfections so surfaces shouldn’t be overly pristine, as they should mimic real-world surfaces with subtle imperfections. For instance, in landscaping, a perfectly even lawn with identical blades of grass and flowers would be unrealistic. Keeping this in mind during rendering is essential.
Similarly, when creating interior design renderings, it’s important to consider small but often overlooked details such as light switches, brackets, plugs, and wiring that would be present in a real-life apartment. These small elements add to the authenticity of the rendering.
Remember, it’s the small details that can make a big difference in achieving a high-quality 3D rendering that is visually convincing and realistic. Taking the time to incorporate these subtle imperfections and commonly overlooked elements into your render can greatly enhance its overall quality and believability.
How to do Architectural Renderings
Architectural rendering involves creating a digital or physical representation of a building or space that accurately portrays its design, materials, and lighting. To create architectural renderings, you will typically need to use specialized 3D modeling software such as SketchUp, AutoCAD, or 3ds Max, among others.
Once you have your 3D model, you can apply textures and materials to create a realistic surface appearance, and then set up lighting and camera angles to capture the scene. Finally, you can render the image or animation using the software, which will generate the final output in the form of an image or video file.
The process of creating architectural renderings can be complex and time-consuming, but with practice and the right tools and techniques, you can achieve high-quality results that accurately convey the design intent and vision for your project.
Conclusion
In summary, achieving realistic and authentic 3D renderings that are of high quality necessitates thorough consideration of various factors.
