Process
Primary Lighting Source &
Color Tone Setup
Atmosphere Adjustment
Adjust the scene contrast, increase the range and intensity of the main light source diffuse reflection, make the main light source more natural. Emphasize light sources and colors from outside the scene to enhance the storytelling of the scene. Adjust the lighting in the foreground to enhance the sense of space

Reflection Refinement
The original painting has a large number of hand-painted highlights, which are difficult to achieve with real lighting conditions, so the highlights need to be adjusted by secondary lighting.
Through two layers of lighting, to achieve the natural excess of different colors and lights inside and outside, to achieve the original painting art effect
Examples
Fish-Eye Effect
Fish-eye Post-process Material
This post-process material simulates the circular perspective stretch from the curved lens of a fisheye lens, but since this material cannot maintain the perspective in the center of the frame and compress the edge perspective at the same time, other commands are needed to assist.
Panini Projection
Cmd: r.Upscale.Panini.D>0
This command was originally used to correct edge stretching in the UE engine due to ultra-wide (ex. FOV=120) perspective, and is used in this scene to simulate perspective compression at the edge of a fisheye lens.
Materials
Process
There are a large number of stainless steel materials in the scene, so one of the most representative assets was selected to demonstrate the material analysis.
Base Color
Select a metal map with thin lines to show the brushed feeling of stainless steel
Water Stains
In reality, the most obvious stains on stainless steel surfaces come from water stains, including water stains that flow down the sides and water stains left by wiping on the countertop.
Dirt and other spill stains
On the surface of stainless steel facilities in public places, there will be some spatter stains where they are in contact with the ground.
Bottom Scratch
At the very bottom of the facility, there will be a smooth and reflective scratch, which is caused by the impact and friction of the shoe.
Stains (Top)
The stains on the top of the countertop are different from those on the sides. The stains on the top are wipe marks and scuffs, which usually appear as curved lines. As well as some flaky water stains and stains.
Tension
Large stainless steel countertops are usually uneven due to stress, and will collapse downward along the direction of the diagonal of the fold and the direction of the edge.
