Why we like it

Inner Chamfer earns its place in the scriptspot library by targeting a narrow but real limitation — chamfering inner corners on Editable Poly meshes — rather than duplicating what 3ds Max already handles on outer corners.

What is Inner Chamfer?

Inner Chamfer addresses a specific gap in 3ds Max modeling: the software's vertex Chamfer operates only on outer corners. This MAXScript makes it possible to chamfer inner corners of Editable Poly objects, and it's described as mostly useful when working with flat surfaces.

The tool exposes three controls. Amount sets the size of the chamfer, Segments defines the number of vertices, and Triangulate builds the chamfer polygon from triangles. If you retopologize surfaces created with the tool, it lets you keep working with flat surfaces using the Opensubdiv or Turbosmooth modifier.

Installation is drag and drop: drop the .mcr file into the viewport, then open Customize > Customize User Interface, find the Veda3d.com category, and assign Inner Chamfer to a hotkey or any UI element. Version 1.1.0 added the Triangulate option and sets a default value of 4, saved in the .ini file, and was tested in 3ds Max 2027.

Who is Inner Chamfer best for?

Inner Chamfer is best for modeling flat surfaces in 3ds Max where inner corners need chamfers that the built-in vertex Chamfer cannot produce.

How much does Inner Chamfer cost?

Inner Chamfer is completely free to download and use.

Frequently asked questions

Does Inner Chamfer work with 3ds Max 2025 and newer?

Inner Chamfer was released as an initial version for 3ds Max 2025 and later, and version 1.1.0 was tested in 3ds Max 2027, so releases in that range are the intended target. It's a MAXScript that operates on Editable Poly objects, meaning your geometry needs to be an Editable Poly for the tool to create inner-corner chamfers. For the current list of supported releases, the developer's page at veda3d.com is the place to check before installing.

How do I install Inner Chamfer in 3ds Max?

Inner Chamfer installs by drag and drop. Drop the .mcr file into a 3ds Max viewport, then open Customize > Customize User Interface and look under the Veda3d.com category. From there you can assign Inner Chamfer to a hotkey or to any element of the UI, so you can trigger it however fits your setup. The download is small, listed at 3 KB, and the .mcr file is the only thing you place into the viewport to get started.

What do the Amount, Segments and Triangulate options do in Inner Chamfer?

Inner Chamfer provides three controls in its interface. Amount sets the size of the chamfer, and Segments sets the number of vertices it produces. Triangulate creates the chamfer polygon from triangles. Version 1.1.0 introduced the Triangulate option and set the default value to 4, which is saved in the .ini file along with the Triangulate setting. These controls apply to the inner corners of Editable Poly geometry, which is where the tool operates.

Can I use Inner Chamfer with the Turbosmooth or Opensubdiv modifier?

Inner Chamfer is described as most useful when working with flat surfaces, and it fits into a subdivision workflow. If you retopologize surfaces created with the tool, it lets you keep working with flat surfaces using the Opensubdiv or Turbosmooth modifier. That makes it relevant when you plan to smooth or subdivide a model later and want chamfers on inner corners as part of the base topology rather than only on outer corners.
