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

Grafico: relevance/impact of every step in the final result
