SolidEnergy
Remember to check for any notes left by the tagger at this article's talk page.
SolidEnergy is a Pixel shader available in all 
Source games since 
Portal 2. (also in 
) It is used for the fizzler, excursion funnel, light bridge, and laser field materials.
Supported effects
$flowmap$flowbounds$translucent$additive$refract(only in
)
Fresnel behavior
Note:When $NEEDSTANGENTT and $NEEDSTANGENTS are both true, $NEEDSTANGENTS is always set to false.
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.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.
etc
Flowbounds
If a flowmap is used, the material uses an additional texture comprised of three greyscale masks on each of the color channels.
- Red controls the flow speed
- Green controls the tint amount from
$flow_color - Blue controls the additive intensity, such as the ripples of a Fizzler
Refract (only in )
These parameters control the refraction effects added in P2:CE.
Bug:Any transparent textures or sprite effects will not render through this texture. Any func_brush with alpha effects applied to it will render on top of this texture. [todo tested in ?]Type 1 (Flowmap) Example
