Top/Bottom Material Support

Overview

  • The Top/Bottom Material is supported to blend two materials’ Diffuse Colors and Opacity channels to produce Color and Density particle data based only on the World orientation of the Particle’s Normal channel (because the Krakatoa Normal Channel is converted to World space at render time).
  • The Blend and Position parameters are supported.
  • No other sub-object parameters will be acquired.

Examples

  • Top/Bottom material with a Red Top and Green Bottom Standard Materials, Blend 0 and Position 50:

  • Same material but with Position 80:

  • Same material but with Blend 50 and Position 80:

  • Same as above, but the Bottom Green Standard Material was set to Opacity of 5.0:
