RULES: Basic 5SRW approach

5SRW is a standard to produce still image for photorealistic images
This standard cover:

• Gamma compensation settings
• Camera
• V-Ray Lights
• V-Ray Sun
• 3d model
• Draft settings
• Final settings
• Denied operations

3D Model:

• Work scale 1:1
• Use detailed models

Gamma compensation:

• in preferences use gamma=2,2 / input=2,2 / output =1,0
• In Render setup: Color mapping >Gamma 2,2
• Always enable V-Ray Frame Buffer
• Don’t active sRGB button

Camera:

• always use V-Ray Physical Camera
• Use Shutter speed = 200 (default) for high amount of light (ex.: exterior with sun)
• Use Shutter speed = 50 for average amount of light (ex.: studio light, interiors)
• Use Shutter speed = 10 for low amount of light (ex.: exteriors night)
• White balance = D65 (default) for exteriors with Sun +Sky
• White balance = Neutral for Studio Light, Interiors
• White balance = 4500°K for night renders
• Do not touch f number (except for creating deph-of-field)
• Do not touch ISO

V-Ray Lights:

• Place Lights just where actually are
• Always use “Watts” as unit
• Always use “Default” as unit for V-Ray Dome use
• Use V-Ray Lights at windows in “portal” mode

V-Ray Sun:

• Don’t touch the parameter “multiplier”
• Use the automatic sky
• Don’t copy the SkyMap in different places

RENDER – Draft quality:

• Enable GI
• Irradiance map = Low
• Light Cache = 500
• Antialiasing = Adaptive Subdivision

( OR just use V-RAY RT for previews)

RENDER – Final quality:

• Irradiance map = High
• Light Cache = 1500
• Antialiasing = Adaptive DMC (min1/max40)
• Noise Threshold = 0,005

Color mapping

• Use Linear
• Use Exponential just in case of unavoidable overexposures

Denied settings:

• do not touch V-Ray Sun multiplier (default = 1,0)
• do not touch primary/secondary bounce value (default = 1,0)
• Never use “V-Ray Environment rollout”
• Don’t disable “dacay” for lights
• Don’t put invisible floating lights in interiors

METHOD – strictly follow the steps:

1. Shot
2. Light Balance
3. V-Ray materials
4. Final Render
5. Post Production
