5 Reasons why your 3D renders appear phoney
5 Reasons why your 3D renders appear phoney
Technology can just get you there
All the world's technology won't help you achieve photoreal photography unless you follow certain simple concepts. And while 3D tech has made tremendous strides in photorealism, at best it can only get you eighty percent. The remaining twenty percent is the difference between a real-looking "kinda" picture and a real-looking one
Builder and buyer
If you're a 3D imaging artist, you know many aspects of a scene need to come together to produce a photoreal image
If you commissioned 3D work, it becomes a little harder, and you feel it just doesn't hit the mark. What's that not working? Finding the issues can be frustrating and time-consuming. This list targets both 3D imagery maker and user. Use it as a guide to review your job, while avoiding some common mistakes

The good news is that certain basic findings result in higher quality levels. Following these simple principles would go a long way toward assisting you in achieving spectacular results
1. Let us discuss sharp edges
Computers excel at precision. The real world is flawed
This is particularly true around the edges of things. Any 3D kit can be used to build a mathematically perfect cube. Any surface would be at a perfect 90-degree angle. Many of the edges are perfectly aligned
Perfectly sharp edges are often unrealistic and unappealing to the eye
Real-world objects do not have ideal mathematical properties. It is theoretically impossible for two surfaces to cross at exact right angles and retain their sharpness. If you look at the intersection of any two planes, you will see rounding, injury, and unevenness
Rounded edges are more natural and add visual appeal
Examine the things around you and notice the various edge qualities that exist
This normal (or artificial) rounding is critical in creating visual accuracy. Why is this so? Since these edges frequently produce highlights. And it is these highlights that serve as important visual cues. They aid in the definition of planes, the division of surfaces, the addition of volume, and the development of visual interest
Be sure to apply bevels to even the sharpest of edges to produce a subtle radius. This is particularly crucial if your objects and surfaces are going to be seen up close
The issue with CAD data
We work with a lot of CAD concept data at The Image Faculty. This is often devoid of fillets and radii. At render time, most render engines have a feature that creates the appearance of a rounded edge. This will save a significant amount of time by significantly increasing realism without the need for additional modelling.Academic Master is a US based writing company that provides thousands of free essays to the students all over the World.

Take note of the sharp edges on this CAD results
The same CAD data as before, but with a round edge shader added
You can take it a step further by incorporating subtle damage into an edge. Popular render engines like Arnold and Vray have their own methods for accomplishing this
Pay attention to the details. Always pay attention to the edges and incorporate rounding
2. Keep an eye out for shadows
3D artists often disregard the form of shadow and, in particular, the edge quality of a shadow. With such a diverse selection of CG lights at one's disposal, it's simple to make a decision that defies reality
It is important to note that these concepts apply to both pre-rendered and real-time lighting scenarios. However, due to technological limitations in realtime engines, the user does not have access to the same lighting options or level of control
Razor-sharp edges are a typical indication of a CG light source. Shadows with no gradient or shift in tone are another dead giveaway
