Features | Reblend

Spectral light

Real light, real color

Reblend renders light wavelength by wavelength, so colors change under each lamp the way they do in real life.

Ten colored spheres in four rows, rendered in Cycles under daylight, tungsten, white LED and high-pressure sodium

The same four rows rendered in Reblend: the colors shift with each lamp, most of all under sodium

Real lamps	Standard daylight, tungsten, LED, fluorescent and sodium lamps, single-wavelength light and your own measured spectra.
Light units	Set lights in watts, lumens, candela, nits or lux.
Dispersion	Glass, water and gems split light into color. Set it on the Principled BSDF or on Reblend Surface.
Diffraction	CDs, DVDs, holographic foil and fine grooves of your own, in every render method.
Fluorescence	Brightened papers, paints and dyes glow under UV and blue light.
Measured colors and metals	Pick a real material's measured color, or one of 37 measured metals.
Thin film	Soap bubbles, oil on water and coated glass.

Caustics

Light through glass

Three methods render the light that passes through glass, liquid and water. Pick one in Render Properties.

A glass ball in sun rendered with Path Tracing: its shadow shows almost no caustic

The same glass ball with Photon Caustics: bright caustics fill its shadow

A glass French press rendered with Path Tracing

The same French press with Bidirectional and Vertex Merging: clean caustics in its shadow

Photon Caustics	Sharp caustics from glass, water and gems.
Bidirectional	For scenes lit through glass, small lamps and light in liquids. Turn on Vertex Merging for the hardest cases.
Glass and liquid together	A drink in a glass renders right without separating the surfaces.
Path guiding on the GPU	Less noise in rooms lit by bounced light.
Bakes	Caustics and light paths in baked textures too.

Camera

A real camera

Put a real lens on the camera, a real film format behind it, and a film stock in it.

Real lenses	77 lens designs, from vintage portrait lenses to cinema primes, anamorphics and fisheyes, each with its own bokeh, distortion, vignetting and focus.
Lens flare	Ghosts and glare from the chosen lens, including lights outside the frame, the sky and glowing objects.
Lens condition	Pristine, Clean, Used or Worn, from a crisp image to a soft veil of glare.
Film formats	23 real film gates and sensors, from 35 mm to 65 mm and IMAX.
Film stocks	8 stocks with their sharpness and grain, and halation around bright lights.
Exposure	Expose by ISO and shutter, like a real camera.
Camera effects after the render	Change lens condition, flare and film on a finished render without rendering again.

Workflow

Nothing to relearn

Your Cycles scenes, materials and lights render in Reblend as they are. You keep working the way you do now and gain spectral light, caustics and real lenses.

W1Video · 10 to 15 s · loopSwitching a Cycles scene to Reblend.

W3Video · 10 sDragging a light with Fast Updates on.

Cycles scenes	Render with their own materials, lights and settings. Principled BSDF and the other Cycles shader nodes keep their Cycles look, in spectral light. Switch a scene back to Cycles any time.
Octane scenes	Render with their Octane materials, textures, lights, environments and camera settings. Reblend flags anything it doesn't support yet.
Fast updates	The rendered viewport keeps up while you move lights and objects.
App or addon	Reblend's own Blender 5.3, or an addon for Blender 5.2 and 5.3.
Every platform	macOS with Apple GPUs, Windows and Linux with NVIDIA and AMD GPUs. Several GPUs render together.

Materials

One node for every material

Your Cycles materials render as they do in Cycles. For a physically exact material, use Reblend Surface.

M1Still · 21:9One object in glass, metal, skin, plastic and liquid.

Reblend Surface	One node for every physical material, with presets for glass, water, diamond, metals and more, and one click to convert a Principled BSDF.
Cycles nodes	Principled, Glass, Metallic and every other Cycles shader node render as in Cycles.
Material library	Ready materials in Blender's Asset Browser, added when you activate Reblend.
Edge Wear	Worn edges on any material.

Cutaways

Cut objects open

Cutters	Cut away part of any object at render time, with solid caps, without touching the geometry.

And more

Texture displacement	Fine surface relief without dicing the mesh.
Light groups	Light groups in every method, each with its own Caustics pass.
Viewport motion blur	See motion blur in the rendered viewport.
Render time estimate	See how long the next render will take as you change samples, noise threshold or resolution.
Baryta	My view transform for product renders, sold on its own for US$29, comes with Reblend.
Themes	Reblend Dark and Reblend Light for Blender.
Render farms	Command-line renders need no license, on any number of computers.
