Description

Lighting
  • Contributors / Receivers — Show the lightmap contributors and receivers for the selected GameObject.
  • Shadow Cascades — Show directional light shadow cascades.
Realtime Global IlluminationVisualize aspects of the Enlighten Realtime Global Illumination system. Refer to GI Visualisations for information about each of these modes.

Miscellaneous
  • Render Paths — Show the rendering path for each GameObject using a color code:
  • Alpha Channel — Render colors with alpha.
  • Overdraw — Render GameObjects as transparent "silhouettes". The transparent colors accumulate, making it easy to spot places where one object is drawn over another.
  • Mipmaps — Show ideal texture sizes using a color code:
    • Red indicates that the texture is larger than necessary (at the current distance and resolution)
    • Blue indicates that the texture might be larger. The ideal texture sizes depend on the resolution at which your application will run and how close the Camera can get to particular surfaces.
  • Texture Mipmap Streaming — Tint GameObjects green, red, or blue, depending on their status in the Texture Mipmap Streaming system. For more information, see documentation on Analyze mipmap streaming.
  • Sprite Mask — Sprite Masks are used to either hide or reveal parts of a Sprite or group of Sprites. For more information, refer to Sprite Masks.
Validate Albedo and Validate Metal SepcularCheck whether your physically-based materials use values within the recommended ranges. For more information, refer to Physically Based Material Validator.
