SUMMARY

SSFR (Screen Space Fluid Renderer) is a rendering tool that converts particle simulations into realistic fluid surfaces. It reconstructs a smooth fluid surface from point data using screen-space techniques and renders it with configurable material properties.

The operator supports two material modes: Refractive for transparent fluid with index of refraction, extinction color, and absorption controls, and PBR for physically based rendering with base color, specular, metallic, and roughness properties. Additional features include bilateral blur for depth smoothing, procedural surface detail, environment map reflections, and tone mapping.

PARAMETERS

PAGESSFR

Render TOP	Rendertop	Reference to the Render TOP where the fluid rendering output is displayed.
Resolution Scale	Resolutionscale	Scale factor for the rendering resolution relative to the Render TOP.
Passes	Passes	Number of bilateral blur passes to smooth the depth buffer.
Filter Radius	Filterradius	Radius of the bilateral blur filter in pixels.
Depth Threshold	Depththreshold	Maximum depth difference allowed during bilateral blur to preserve fluid edges.
[+]Material Type	Materialtype	Rendering material mode for the fluid surface.
Thickness Scale	Thicknessscale	Scale factor for fluid thickness affecting absorption and refraction calculations.
IOR	Ior	Index of refraction for the fluid surface.
[+]Extinction Color	Extinction	Color absorbed by the fluid over distance, controlling the tint of thick regions.
Absorption Scale	Absorptionscale	Multiplier for the absorption effect based on fluid thickness.
Refraction Scale	Refractionscale	Strength of the refraction distortion through the fluid surface.
[+]Base Color	Basecolor	Base color of the fluid surface in PBR mode.
Specular Level	Specularlevel	Intensity of specular reflections on the fluid surface.
Metallic	Metallic	Metallic appearance of the fluid surface. Higher values create more reflective, metal-like surfaces.
Roughness	Roughness	Surface roughness of the fluid. Lower values create sharper reflections.
Ambient Occlusion	Ambientocclusion	Strength of ambient occlusion darkening in fluid crevices.
[+]Emit	Emit	Emissive color added to the fluid surface.
[+]Constant	Constant	Constant color added to the final rendering output.
Enable Surface Detail	Enablesurfacedetail	Enable procedural surface detail on the fluid.
Detail Resolution	Detailresolution	Resolution of the surface detail noise texture.
Detail Period	Detailperiod	Spatial frequency of the surface detail pattern.
Detail Strength	Detailstrength	Intensity of the surface detail displacement.
Environment Map	Envmap	Reference to a TOP used as the environment map for reflections.
Render Environment	Renderenvmap	Render the environment map as a background behind the fluid.
Enable Tone Map	Enabletonemap	Enable tone mapping on the rendered output.
Gamma	Gamma	Gamma correction value for the tone mapped output.
Exposure	Exposure	Exposure adjustment for the tone mapped output.
