Managing 3D rendering includes several different aspects that need your attention. Focusing on these aspects will help you to increase the effectiveness of your renderings. With these expert tips, you will gain crucial knowledge that will help you create real, high-quality 3D renders.
You need a fully functioning methodology to create the most realistic 3D renderings. But, incorporating that methodology is just one piece of a much bigger puzzle. Merely correcting the modeling or lighting isn't enough to offer effective 3D renderings that sell.
Of course, a lot depends on your knowledge regarding 3D rendering software since you don't want a bad render limiting your possibilities and ruining all that effort. When managing your 3D renderings, you have to work on making them look as realistic as possible.
With all this in mind, here's a list of the most useful expert tips that should help you create the most realistic, high-quality 3D renderings that will beat the competition and make you stand out from the rest.
1. Start simple
Simplicity is always the best, especially when you're doing complicated and complex designs. Shift your focus to leading proper curve lines and maintaining a simple shape. This is extremely important in the modeling stage. The moment you establish the main shape, you're clear to focus on the tiny details.
2. Don't be afraid of fresnel shaders
Fresnel or incidence angle shaders help you put together multiple basic shaders. Blend between them to capture a specific angle. This gives your 3D rendering a more realistic look. Enrich the normal mode of your shaders with textures to create the wanted effect more efficiently.
3. HDRI matters
In 3D rendering, shape really matters. To properly accentuate the shape, use high contrast, high dynamic range imaging (HDRI). This greatly helps to enhance mirroring along the curvature of your 3D rendering model. Light information affects your entire model. So, the higher the resolution, the better the output.
4. Additional lighting is always a good idea
There will be situations when HDRI or your environment won't be enough. This is a great moment to consider additional light sources. Highlights are great at emphasizing the shape of your model, especially when it comes to making silhouettes stand out.
5. Consider composition
When creating a 3D rendering model for the viewer, you can use focal points and guidelines to lead the viewer through the first, second, and third plane of your entire 3D rendering scene.
Consider additional close-ups and focal points in an attractive and interesting environment. This will help you wow your audience and cash in your work. The color pallet of your environment should be as pleasant as possible. Use camera movement to add dynamics to your shots.
6. Pay special attention to every edge
The modeling stage is all about beveling every edge down to the tiniest detail. This greatly contributes to making your 3D rendering as realistic as it gets. You can add a really great and more realistic light reflection to many deflective elements (such as a light diffuser) by adding a subtle slope.
7. Gathering reference material greatly helps
3D rendering is like anything else in the world; someone already did it. So, if you're required to model something that already exists, gathering as much reference material as you possibly can help you make the most of it.
More importantly, this will get you valuable views from the front, side, and top. This is exactly what you need to make your model look perfect and more realistic from every angle. Every single detail matters, especially the proportions.
8. Real-world scaling helps make photorealistic renderings
Real-world scaling allows you to make your 3D rendering model appear photorealistic. Every detail including scene lighting needs to behave the same as in real life. This is extremely helpful, especially when it comes to introducing dynamics or future-proofing.
9. Keep the mesh clean
Make sure to keep the mesh comparatively low-poly and as clean as possible. This is a great 3D rendering technique that makes working on complex 3D models much easier. Aside from that, it also keeps the size of the entire scene on lower levels which makes your model more easily adaptable to any scenario.
10. Even the tiniest detail can alter the perception
3D rendering is all about every single detail. It's incredibly important to pay special attention to every detail as they have the capacity to make or break your 3D rendering model. Since everything comes down to the level of perception, you can't ignore small details or use any shortcuts.
Regardless of how small these details are, they are highly influential in making the audience believe your model is real. If you want to become good at 3D rendering, paying attention to details is one of the things that matters the most.
11. Override materials are recommended if need be
The background colors of the environment tend to overpower the images of 3D rendering models. This directly affects the refraction, GI, and shadow colors. While this is not a big deal in most cases, there are some exceptions. You can easily manipulate such effects if you have a proper tool (such as VrayOverrideMtl).
12. Linear workflow is more than welcomed
A 32-bit linear workflow works like a charm when you need to make your 3D renderings as realistic as possible. Going with 8-bit images is fine too but there can be a certain level of misinterpretation if you're viewing these images on anything larger than your monitor.
The visible image will look much darker which requires certain adjustments such as increasing the intensity and adding more lights.
To avoid wasting time on this rather daunting process, incorporate a linear workflow to make your render devoid of all those flaws. This allows you to use real-world lighting to make your images look more natural and photorealistic.
13. V-ray settings
If you're a beginner, this setting might turn out to be a difficult one. But, if you're an experienced 3D rendering artist, you'll deal with it with sheer skillfulness. It goes like this.
You have the key, natural light that provides the necessary brightness for your model and this strongly affects the look of your scene.
Since there is also a light on the opposite side that helps keep the shadows at a minimum, you need the back-light that will go behind your model. This will give your model that three-dimensional look and make it stand out more in the eyes of the audience.
There are so many other tips worthy of mentioning here. But, these are the most important ones that should help you take your 3D rendering knowledge and skills to a whole new level.
