A spectral render engine for Blenderv1.0 / RESEARCH PREVIEW

Light,computedto the photon.

A spectral render engine for Blender — dispersion, iridescence and fluorescence, the light effects RGB simply can't reach. Cycles-compatible scenes and nodes, so it drops straight into the workflow you already have.

01 — Vision

Threenumbers.

Conventional path tracers describe color with red, green and blue. A convenient fiction — three coordinates standing in for a continuum.

An entirespectrum.

Reality is continuous. Dispersion, fluorescence, thin-film interference and metamerism live between the channels — where RGB cannot reach.

Measured,not guessed.

We sample the full visible band per ray, then reconstruct the observer response with calibrated colorimetry. Not a style. The correct answer, rendered.

02 — Capability

Four primitives.
One model of light.

C.01

Full-spectrum transport

Per-wavelength sampling with importance-weighted hero wavelength spectral sampling for low-variance dispersion and caustics.

λ 380–730nm · 32 BINS
C.02

Measured materials

Layered BSDFs driven by spectral reflectance data, not artist guesses. Import lab measurements straight into the shading graph.

CIE 1931 · 2°/10°
C.03

Deterministic scaling

Identical results across one workstation or ten thousand cores. Reproducible seeds, bit-stable across the render farm.

CPU · CUDA · OptiX · HIP
C.04

Calibrated output

ACES, spectral upsampling and display-referred grading inside a single color-managed pipeline with auditable provenance.

OpenColorIO · OpenEXR

02 / END

One continuous
model of light.

03 — System

The pipeline,
made legible.

// Every frame ships with a manifest: seed, build hash, spectral configuration and per-stage timings. Nothing is unaccountable.

Precision is not a feature. It is the premise.

04 — Proof

Measured,
not asserted.

05 — Enterprise

Built for the people
who cannot be wrong.

SPYCLES is deployed where the image is evidence — product design validation, automotive material approval, scientific visualization and high-end film. Where a render is a decision, not a draft.
