3d Rad Exporter Plugin May 2026

If you want to build a "3D Rad Exporter" for a specific software (like Blender), do not build a 3D Rad plugin. Build a Blender Python Add-on.

Why? 3D Rad imports standard formats (OBJ, X, 3DS). If you write a plugin that exports to these formats from Blender/Maya, 3D Rad will automatically accept them.

Step-by-Step for a Blender Exporter:

Many users search for "3d rad exporter plugin" because they have an FBX file from Sketchfab, Unity Asset Store, or another engine. There is no direct FBX to .RAD plugin. However, there is a two-step workflow using Blender as a bridge. 3d rad exporter plugin

The Indirect Export Workflow:

This method works for static props, vehicles, and even animated characters, provided the armature is properly weighted.

If you want, I can:

Since 3D Rad is legacy software (development ceased around 2013) and lacks the active ecosystem of modern engines like Unity or Unreal, "exporter plugins" are typically custom C++ DLLs or wrapped file interpreters that translate data from a specific format into something 3D Rad can read at runtime.

Below is a comprehensive guide on how to create a 3D Rad Exporter Plugin. This guide assumes you are trying to bridge a modern 3D tool (like Blender) or a custom format into 3D Rad.

Modern radiation transport codes (such as MCNP, GEANT4, or proprietary RAD engines) require highly specific geometry definitions. These engines typically rely on Constructive Solid Geometry (CSG) or boundary-representation (BREP) meshes. If you want to build a "3D Rad

However, designers and engineers typically work in high-end 3D modeling software (e.g., Blender, Maya, SolidWorks). Exporting from these environments often results in:

Physics in 3D Rad relies on collision cubes/spheres/meshes. A quality exporter plugin will analyze your mesh and generate an invisible "collision hull" automatically, or let you assign a separate mesh named _collision.

The plugin operates on a three-stage pipeline: Analysis, Enrichment, and Compilation. Many users search for "3d rad exporter plugin"
