This document provides tips for creating photorealistic 3D renderings of interiors and exteriors. It recommends experimenting with lighting at different times of day, adding reflections to shiny surfaces, adjusting shadows for depth and realism, using high-resolution texture photos to make materials look natural, introducing small imperfections to emulate real-world conditions, and compositing additional real-world elements into renders. The goal is to trick viewers into thinking the computer-generated images are actual photographs.

2. The biggest compliment to a 3D artist is when someone
looks at their creation and is convinced that it is not a
computer generated image, but a photograph taken
from reality. While there are those who seek a fantastic
and whimsical look for their 3D rendered images,
achieving photorealistic results is still considered the
“holy grail” of the rendering world. So if you are looking
to create “awesome” indoor and outdoor 3D shots, read
on for tips on how to get that realistic effect on them.

3. Change Your Lighting - As every artist knows, lighting
is crucial for any 3D interior design. Play with and
experiment with lights that represent different times of
the day. You are sure to make the scene more real.
Create Reflections: Examine every object in your
scene and analyze which ones would normally have
reflective surfaces. Some examples are bodies of
water, shiny ground, and the metallic surface of a car.
Creating highlights for these will do wonders for your
rendering to be realistic.

4. Cast Shadows - Shadows add depth to the scene and are essential
for a natural look. Adjust the lighting to get a good play of light and
shadow in your view. Making it too sunny in an outdoor 3D shot or
inserting too many light sources in an indoor 3D shot reduces the
number of shadows so that the final image looks very flat. On the other
hand, insufficient lighting would not allow you to see objects and
recognize them clearly. This is why it is important to choose the
optimum amount of lighting for your 3D rendering.
· Use natural looking textures: Instead of using those from a 2D
painting program, grab your textures from photos and use them to
create your maps. It will make a difference to make materials like
fabrics, stone, wood and concrete look natural. Make sure to use high
resolution photos so that minor natural flaws are apparent and bring a
whole new level of realism to your works.3D Architectural rendering

5. Make it Imperfect: Nothing in the real world is perfect
and if you want people to believe your 3D rendered
image is a photograph, you have to emulate this
imperfection. A small stain on the wall here and a slight
wrinkle in the fabric is enough to confuse people.
Fix Things - Use 2D photo editing software to add
objects such as real images of trees, shrubs, and
people to your rendered interior and exterior 3D
images.
