Clearcoat
Car paint, lacquer and glaze, with light bouncing between the layers for real depth.
Opal spectral engine · in your browser
Light, rendered as it really behaves.
Bring a model from Cinema 4D, Blender, 3ds Max or any glTF app, and Opal renders its glass, metal and paint with the physics of real light. Every result is checked against pbrt-v4, the reference renderer.
Free, with no account and nothing to install. Your files never leave your computer.
Spectral
Every ray carries real wavelengths of light.
Most renderers mix red, green and blue. Auddomate Render follows light as a spectrum, four wavelengths at a time, so colors bleed, reflect and split exactly as they do in nature. Dispersion through glass isn’t an effect we add. It simply happens.
- Four wavelengths on every path
- Every color turned into a smooth spectrum
- Prism-true dispersion in crown glass
Glass
Glass that bends the world behind it.
Solid glass refracts and flips what’s behind it, reflects where Fresnel says it should and traps light at steep angles. Frost it, thin it into a window or fill it with water.
- Refraction and total internal reflection
- From crystal clear to fully frosted
- Thin glass for windows and screens
- Labels printed on glass
- Sharp caustics where sunlight passes through
Materials
Metal, paint and plastic, catching the light the way they should.
Every surface carries its own reflection, strongest at the edges: the Fresnel effect that makes objects look solid. Roughness and normal maps bring the wear, grain and fingerprints you painted. Wax, jade, milk and marble glow from within, as light scatters inside them.
Metals
Gold, copper and chrome with exact color shifts at the edges, from mirror to brushed.
Surface maps
Roughness and normal maps straight from glTF and OBJ, so detail costs no triangles.
Textures
Paintwork, labels and decals, with transparent and cut-out areas handled properly.
Proof
Checked against pbrt-v4. Every release.
pbrt is the reference renderer behind the standard textbook on physically based rendering. Every feature in Auddomate Render is rendered by both and compared block by block, and the checks ship inside the studio for anyone to run.

Workflow
From your 3D app to a finished file.
- 01
Import
Send your scene from Cinema 4D, Blender or 3ds Max in one click, or drop a GLB, glTF or OBJ. Cameras, materials and lights come with it.
- 02
Light
Studio softboxes, a physical sky and sun, any HDRI, or one even color all round.
- 03
Save
Stills up to 8K as JPEG, PNG, 16-bit TIFF or EXR, and animations as MP4 video.
