No export from Rhino. No FBX, OBJ or DWG in between. R2M reads the .3dm directly and builds its layers, block instances, materials and cameras in Max. Rhino doesn't even need to be installed.
Pick the .3dm in Max. Rhino can stay closed, or not be installed at all.
Objects saved without render meshes are meshed by R2M. It starts in 0.1 s.
Prefer Rhino's mesher? R2M runs your Rhino 8 headless, in the background.
1.02 million triangles in 2,000 objects, built in 0.3 s.
Geometry goes into Max through R2M's C++ builder, not a script loop. Render meshes are read on all cores while the file's tables load. Merging, welding and edge cleanup run in parallel.

start-up of the built-in mesher. A cold Rhino 8 start takes 5 to 12 s.
Measured by us in 3ds Max 2026 on one workstation, November 2026. Left: synthetic scene, best run in 3ds Max batch mode. Right: blocks exploded, merged by layer and material into Editable Poly, weld and clean edges on; three runs each. A 27.9 million triangle stress file went from 116 s to 51 s. Your times depend on CPU, disk and network.
3ds Max 2026 has no .3dm importer of its own, so the usual route is exporting FBX or OBJ from Rhino every time the model changes. R2M reads the file instead, meshes whatever Rhino didn't save, and lets you choose which mesher does it.
Breps, extrusions, surfaces, SubD, meshes, nested blocks, layers, materials, named views.
Rhino saves them when you shade a view. R2M reads them on all cores with openNURBS. Nothing to compute.
For files saved small, never shaded or cleared of meshes. C++, starts in 0.1 s. Watertight Breps; SubD on the limit surface.
Want Rhino's own mesher? R2M runs your installed Rhino 8 in the background, without a window.
Editable Poly or Editable Mesh with Rhino's normals and UVs, welded, with clean edges.
Layers, names, blocks and materials come across as Max objects you can work with. Every node keeps its Rhino ID, so the scene can be updated later.
Names, nesting, visibility and colours become Max layers. Filter which layers to import; choose whether hidden and locked objects come along.
One mesh per block. Every placement becomes a Max instance, nested blocks too. Never baked into copies.
Chair × 16 → 1 mesh, 16 instances
Rhino materials, PBR included, become VRayMtl, CoronaPhysicalMtl or Physical Material. Per-face materials become Multi/Sub. Objects without a material get their layer colour.
Bitmaps embedded in the .3dm are extracted next to your scene. Broken paths are also searched next to the .3dm and in its sub-folders.
missing textures on one production file, before and after extraction
V-Ray, Corona or Physical cameras with Rhino's lens and aspect. Verticals can be straightened for two-point perspective.
Model units are converted to your system units. Or force mm, cm, m, inches or feet. Objects far from the origin keep their precision.
Object names become node names. Each node stores its Rhino ID, which is what Re-sync matches on.
Import the updated .3dm into the same scene. R2M matches every object by its Rhino ID and only touches what changed.
Big Rhino models arrive as tens of thousands of objects. R2M analyses the file first, then merges what doesn't need to stay separate, without mixing materials.
Pick a file and R2M scans it in the background, then recommends a setup: merge mode, which blocks to keep as instances, which mesher.
By layer, by material, by layer + material, or Smart: groups that never mix materials, with heavy blocks kept as instances. Merged meshes get material IDs and a Multi/Sub.
Weld, clean edges (coplanar triangles back into the polygons you modeled) and Rhino's own normals, or auto smooth. Editable Poly by default.
Keep Breps as R2M Brep objects that tessellate inside Max. At render time the density can follow the camera: 0.5 px chord deviation per view by default, dense up close, light in the distance.

Download free trialNo. R2M reads the .3dm itself. Objects saved with render meshes import as they are. Objects without them (Save Small, never shaded, or after ClearAllMeshes) are meshed by R2M's built-in mesher. If Rhino 8 is installed, you can mesh with Rhino instead: R2M runs it in the background, without a window.
3ds Max 2026 on Windows. R2M reads .3dm files saved by Rhino 8 and earlier. The optional Rhino mesher needs Rhino 8.
No. 3ds Max only runs on Windows, so R2M is Windows-only. The .3dm can come from Rhino for Mac.
V-Ray, Corona and the 3ds Max Physical Material. Rhino materials, PBR included, become VRayMtl, CoronaPhysicalMtl or Physical Material. Named views become V-Ray, Corona or Physical cameras.
Yes, with Re-sync. R2M matches objects by their Rhino ID. Changed objects get new geometry in place and keep the materials, modifiers and transforms you added in Max. New objects are added. Deleted objects are hidden on the layer R2M_Deleted, or removed if you prefer.
Import and Re-sync stop until you have a licence again. Scenes you already imported open and render as before: imported objects are ordinary Editable Poly or Editable Mesh objects. Only the optional R2M Brep objects need R2M installed to display; they never need a licence to open or render.
One seat runs R2M on one machine at a time. To move a seat, release the machine from inside 3ds Max (up to 5 moves per 30 days). Buy as many seats as you need in one order.
Only to sign in and to check the licence, about once a day. After a check it keeps working offline for up to 14 days (30 days on lifetime licences).
No. Reading, meshing and building run on your machine. The licence check sends your account, a hashed machine ID, the machine name and version numbers. Never the file.
It depends on the file and the machine. On our workstation, 1.02 million triangles in 2,000 objects build in 0.3 s, and a 1.1 GB production file imports in about 28 s. Try your heaviest file during the trial.
