SolidEnergy is a s0 available in all Source games since Portal 2. It is used for the fizzler, excursion funnel, light bridge, and laser field materials. Also available in CS:GO.

Todo: Properly document this!

Todo: Add images

Supported effects

• $flowmap
• $translucent
• $additive
• $refract (only in )

Todo: What other effects does this shader support?

Fresnel behavior

$TANGENTTOPACITYRANGES $TANGENTSOPACITYRANGES $FRESNELOPACITYRANGES $NEEDSTANGENTT $NEEDSTANGENTS

Note:When $NEEDSTANGENTT and $NEEDSTANGENTS are both true, $NEEDSTANGENTS is always set to false.

$NEEDSNORMALS

Powerup and vortex parameters

These material parameters are used to control the power-up animation, and up to two vortexes which normally appear when objects are nearby. They are generally set by the FizzlerVortex proxy.

Tip:A MaterialModify proxy can instead be used to control the effects manually, for custom fizzlers.

$powerup $FLOW_VORTEX1 $FLOW_VORTEX_POS1 $FLOW_VORTEX2 $FLOW_VORTEX_POS2

Detail

When using a basetexture, the shader also renders 2 optional detail textures, which are blended with the basetexture. Both of these detail textures use the same syntax of variant parameters as $detail, with "$detail1" or "$detail2" replacing the "$detail" prefix. (eg: $detail1scale 1) This method must be used if the material is to be used on a model, as meshes will not render if a flowmap is applied.

$detail1 $detail2 etc

Type 1 (Flowmap) Example
