Icicle flags control various aspects of the appearance of an object. Many of them are automatically set as needed by PyPRP, but in some cases specifying them manually can be useful.

Overview

Possible values in the visual.icicle list are the following:

MyObject:
    visual:
        icicle:
          - litematerial
          - nodraw
          - noshadowcast
          - facessortable
          - volatile
          - waterheight
          - runtimelight
          - reversesort
          - haspermalights
          - haspermaprojs
          - litevtxpreshaded
          - litevtxnonpreshaded
          - liteprojection
          - liteshadowerase
          - liteshadow
          - mathasspecular
          - projasvtx
          - skipprojection
          - noshadow
          - forceshadow
          - disablenormal
          - character
          - partialsort
          - vislos

When this flag is set, vertex colors are multiplied to the overall color after addition of the diffuse contribution of real-time light sources. In other words, a black vertex color will eliminate all light shining on the surface, while a white vertex color will leave it unchanged. This is appropriate when vertex colors are used to simulate shadows from light sources that are still present as real-time lights.

When this flag is not set, vertex colors are multiplied to the overall color before addition of the diffuse contribution of real-time light sources. In other words, a surface with a black vertex color will be illuminated normally by real-time lights, and a white vertex color will add to the real-time light. This is appropriate when vertex colors are used to simulate the diffuse lighting from light sources that are not present as real-time lights.

PyPRP automatically sets this flag on objects that have an Alpha vertex color layer.
