V-Ray 3ds Max to Cinema 4D — Keep Every Material

The V-Ray Ecosystem: Max vs C4D

V-Ray for Cinema 4D is a full native port maintained by Chaos Group. The core material types — VRayMtl, VRayBlendMtl, VRayBitmap, VRayNormalMap — exist in both the 3ds Max and Cinema 4D versions. The parameter names, BRDF models, and rendering behavior are essentially identical across platforms. If a VRayMtl looks correct in 3ds Max, it should look correct in Cinema 4D given the same property values.

But there is no built-in way to transfer V-Ray scenes between 3ds Max and Cinema 4D. Chaos Group does not provide a scene interchange tool. FBX export strips all V-Ray data completely — every VRayMtl becomes an empty Standard material, every VRayBitmap connection disappears, and the entire shader graph is gone. You're left with gray geometry and an empty material editor.

MAX2C4D bridges this gap. It reads V-Ray materials directly from the .max file through the 3ds Max SDK and rebuilds them as native VRay for C4D shaders — preserving every property, every node connection, and every texture path. The result is a Cinema 4D scene that renders identically to the original 3ds Max project.

V-Ray Material Types That Transfer

MAX2C4D supports 15+ V-Ray material types. Each is recreated as its native VRay for C4D equivalent with all properties mapped — not approximated with a Standard material, but rebuilt as the exact same material type with the same parameter values.

Every material type is rebuilt node-by-node. VRayMtl alone has over 40 transferable properties including diffuse color, roughness, metalness, reflection glossiness, IOR, refraction, SSS radius, coat weight, coat roughness, sheen color, sheen glossiness, thin film thickness, and more.

V-Ray Shader Nodes: Full Graph Preservation

Materials are only half the picture. A production V-Ray scene uses dozens of shader nodes wired together in complex node graphs — bitmaps feeding into color corrections, triplanar projections, compositing layers, and randomizers. MAX2C4D preserves these node graphs completely, not as approximations but as exact recreations of every connection.

If a VRayBitmap feeds into VRayColorCorrection, which feeds into VRayCompTex, which connects to the roughness slot of a VRayMtl — that entire chain is recreated exactly in Cinema 4D. No flattening, no baking, no approximation. The node graph you built in 3ds Max is the node graph you get in Cinema 4D.

3ds Max (V-Ray)

Cinema 4D (V-Ray via MAX2C4D)

Same V-Ray scene — left is the original 3ds Max render, right is the Cinema 4D conversion via MAX2C4D. Materials, textures, and lighting transfer with full fidelity.

Cross-Renderer Conversion: V-Ray to Corona

One of MAX2C4D's strongest features is cross-renderer conversion. If you don't have VRay for C4D installed — or if you simply prefer Corona — MAX2C4D automatically converts all V-Ray materials to their native Corona equivalents. This is not a lossy fallback; it's a full property-level mapping between the two renderers.

You can control this behavior with the renderer dropdown in the MAX2C4D importer. Three modes are available:

V-Ray Render Settings and VideoPost

Materials are critical, but render settings determine how those materials actually look in the final image. MAX2C4D transfers approximately 130 V-Ray render parameters via Cinema 4D's VideoPost system — so you don't have to manually copy sampler settings, GI configuration, or tone mapping values from screenshots of the 3ds Max render dialog.

The goal is render parity: you open the converted Cinema 4D scene, hit render, and the output matches the original 3ds Max result. No manual tweaking of sampler subdivisions or GI solver settings. The render pipeline transfers alongside the materials.

V-Ray Advanced Objects

Production V-Ray scenes rely on more than materials and render settings. MAX2C4D handles V-Ray's specialized scene objects — the proxies, volumetrics, and effects that make complex scenes work.
