SSFR v1.2.0

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

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.

Refractive refractive

PBR pbr

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.

Extinction Color Extinctionr

Extinction Color Extinctiong

Extinction Color Extinctionb

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.
