Set Recommended Options

This button is used to achieve maximum consistency between the look of a 3D scene in Blender viewport and in web browser. Pressing this button:

  • enables World Space Shading,
  • switches material mode to GLSL,
  • switches viewport shading mode to Material and
  • sets the main camera fit to Vertical.

Ratio
