Beginner's GI tutorial

From Realsoft3D Wiki



This tutorial gives the user minimal knowledge on how to use Global Illumination in RS3D. The text should be idiot proof, so feel free to edit it.

Scene Setup

  • Open RS. This is important.
  • Create a simple scene with an analytic disc as the ground (tick infinite on from properties->spec) and a sphere on it as our main character.
  • Set the ground's color to (0.85 0.85 0.85) and the sphere's color to (0.9 0.3 0.2).
  • Create another sphere in the world center and set it's size to, say, 100, 100, 100.
  • Open its properties window and tick shadow invisible and hollow in the Gen-tab.
  • Then go to the col tab and set Color to (0 0 0) and Illumination to (0.25 0.3 0.45).
  • Create a Point Light to represent the sun, place it so that you get nice shadows.
  • Set its color to (0.9 0.7 0.3) and strength to 1 (or whatever you find suitable).
  • RMB on the view window and go to View Properties->Camera, set Flashlight to (0, 0 ,0 ).


GI Setup

  • Select the ground and the sphere
  • Go to the material tab and drag&drop the GI_shader to the view window
  • Go to the Render Setting tab and drag&drop the GI rendering setting to the view window
  • Go to the Post Image tab and drag&drop the GI_effects Post Image to the view window


  • Place the camera at a dramatic angle
  • Press 0
