Spectra Render™

The Reality Engine — realtime wave-optics path tracing for Blender.

Maxwell's equations as the substrate, not a post-process. Spectral, polarized, and unbiased by construction — running in realtime on NVIDIA, AMD and Intel GPUs through Vulkan ray tracing.

Character rendered by Spectra Render

Rendered by Spectra. No RGB approximations anywhere in the pipeline.

Wave optics by construction

Hero-wavelength spectral transport, Stokes-vector polarization, dispersion, thin-film interference and edge diffraction — physics that RGB renderers can only fake.

Realtime IPR

Scene state lives on the GPU. Scrub the camera, drag a material slider — the image responds instantly, with AI denoising on top of an unbiased core.

A Blender addon, not a fork

Installs like any addon. Uses your Principled BSDF materials, your lights, your scenes — on stock Blender 5.1+. NVIDIA, AMD and Intel ray-tracing GPUs supported.

In beta — coming to Superhive
