How to Convert 3ds Max Scenes to Cinema 4D (2026)
The complete guide to keeping Corona and V-Ray materials intact when moving from 3ds Max to Cinema 4D.
Why Converting 3ds Max to Cinema 4D Is Hard
The geometry isn't the problem. The materials are.
3ds Max scenes in architectural visualization and product rendering almost always use Corona Renderer or V-Ray materials with complex node graphs. A typical Corona scene uses CoronaPhysicalMtl with nested CoronaBitmap, CoronaColorCorrect, and CoronaMixMtl chains. V-Ray scenes use VRayMtl, VRayBlendMtl, VRayBitmap, and VRayNormalMap trees.
These are renderer-specific material systems — they don't exist in any interchange format. Standard exports like FBX and OBJ can transfer geometry, but they have no concept of CoronaPhysicalMtl's metalness model, SSS parameters, or clearcoat layers. Same story for VRayMtl's BRDF, coat layers, and translucency channels.
For renderer-specific deep-dives, see the Corona materials guide and the V-Ray render settings guide.
Method 1: FBX Export
Avoid for archvizBuilt into both apps. Loses everything that matters.
The workflow
- Open your
.maxfile in 3ds Max - File → Export → FBX
- Import the resulting FBX file in Cinema 4D
What you get
- ·Geometry with basic transforms
- ·Object hierarchy
- ·Animation keyframes
What you lose
- ×All Corona materials
- ×All V-Ray materials
- ×Every shader node graph
- ×Multi/Sub-Object assignments
- ×Render settings + ForestPack
- ×Corona/V-Ray lights + cameras
The result is gray, untextured meshes with an empty material editor. For a typical archviz scene, that means 4 to 8 hours of manual material rebuilding after an FBX export — opening the original Max scene on a second monitor, screenshotting every material's settings, recreating them one by one, relinking every texture path, redoing Multi/Sub-Object assignments, reconfiguring render settings from memory.
For a deep dive into exactly which channels FBX destroys, see the MAX2C4D vs FBX comparison.
Method 2: Manual Rebuild
Pixel-perfect, day-longSkip FBX entirely. Rebuild every material from screenshots. Wait 1-2 days.
You open the Max scene on a second screen, screenshot every material's node graph, and rebuild each material from scratch in Cinema 4D's Node Editor or material manager. Every CoronaBitmap becomes a Corona Bitmap shader in C4D. Every CoronaColorCorrect needs its gamma, contrast, and hue shift values copied over. Every Multi/Sub-Object material needs Selection Tags created on the corresponding geometry.
It works — you can achieve a pixel-accurate result if you're meticulous enough. But for a scene with 200 materials, each with 3 to 15 node connections, expect 1 to 2 full days of tedious work.
“Every revision is a full restart.”
The client sends V2 with new materials, fresh furniture, different lighting — and you do it all over again. There's no way to “update” a manual rebuild.
The manual rebuild approach detailed breaks down the per-material time cost. If you're considering free converters instead, check the MaxToC4D alternative comparison — spoiler: they don't handle Corona or V-Ray graphs.
Method 3: MAX2C4D
RecommendedNative Corona & V-Ray shaders. Node-by-node. 43 seconds.
MAX2C4D is a Cinema 4D plugin that converts 3ds Max scenes directly — with full Corona and V-Ray material preservation. Instead of losing your materials to an interchange format, MAX2C4D reads the .max file and recreates every material as a native renderer shader in Cinema 4D.
How it works
- 1
Pick your .max
Select your .max file from within Cinema 4D using the MAX2C4D dialog.
- 2
Headless export
MAX2C4D launches 3ds Max in the background — you never need to open it manually.
- 3
Geometry as OBJ
Geometry exports as OBJ — 27× faster than FBX for polygon data, no precision loss.
- 4
JSON scene graph
Materials, lights, cameras and render settings serialize as structured JSON — the format that preserves what FBX cannot.
- 5
Rebuild as native shaders
C4D importer reads the JSON and rebuilds each material as native Corona for C4D or V-Ray for C4D, node by node.
- 6
80+ shader nodes mapped
Full graphs preserved — CoronaPhysicalMtl, VRayMtl, Multi/Sub-Object with Selection Tags, ColorCorrect chains.

“Got a .max scene from a client on a Friday afternoon. Imported in C4D, lit it, rendered the same evening. Used to take me a full day of rebuild.”

- Object hierarchy and grouping preserved
- Asset library migration for batch flows
Common Issues and Solutions
“Missing textures after conversion”
Texture paths weren't accessible during the export step. MAX2C4D copies all textures to a clean /tex folder alongside the converted scene. If the originals were on a NAS or network drive that was disconnected at export time, the files won't be found. Reconnect the drive and re-export.
“Some materials show as Standard”
Target renderer not installed on the Cinema 4D side. MAX2C4D recreates Corona materials as native Corona for C4D shaders and V-Ray materials as native V-Ray for C4D shaders. Install Corona for Cinema 4D or V-Ray for Cinema 4D before importing.
“ForestPack density looks different”
ForestPack uses grid-based distribution, Chaos Scatter uses density-based. The conversion maps density, transforms, include/exclude zones, clustering, slope limits — but the algorithms differ. Fine-tune the density value in Chaos Scatter after import.
