Why we like it

Reforge earns its place in the Blender extensions library for its focused Blender to Defold export pipeline, with .go files preserved on re-export and legacy project auto-migration.

What is Reforge?

Reforge is a Blender add-on that converts Blender mesh objects into Defold-ready assets. It exports .glb meshes, .model files with multi-material support, .go prefabs that are never overwritten, and .collection scenes with grouped instances. The add-on also supports optional convex collision export, texture copying into the Defold project, and safe cleanup of exporter-specific custom properties, and is designed for clean and repeatable Blender to Defold pipelines.

Version 0.5.2 adds color texture baking to PNG, including solid-color materials and complex node graphs such as Ucupaint. It allows exporting a single selected prototype (GLB, .model and textures) without rebuilding the .collection, as well as exporting all prototypes while keeping the existing collection intact. The material pipeline handles objects with multiple material slots by exporting entries by material slot name, and objects named like Object.001 or Object.002 can be automatically grouped under the same prototype.

This release also keeps .go files intact on re-export so manual components like collisions and scripts remain, supports legacy projects with automatic migration, uses a grouped hierarchy in exported .collection files, and provides safe clear tools with confirmation plus foldable UI sections.

Who is Reforge best for?

Reforge is best for blender users building clean, repeatable Blender to Defold asset pipelines.

How much does Reforge cost?

Reforge is completely free to download and use.

Frequently asked questions

Does Reforge work with Blender 4.2 LTS?

Reforge is compatible with Blender 4.2 LTS and newer, so it runs on 4.2 LTS and later releases. You can add it by dragging and dropping the extension into Blender, or by downloading the add-on and installing it from disk through Blender's extensions preferences. The current version is 0.5.2, published in January 2026, and it does not require special permissions. For source code and issue reporting, the developer maintains a repository linked from the add-on's page.

What Defold asset types does Reforge export?

Reforge converts Blender mesh objects into Defold-ready assets. It exports .glb meshes, .model files with multi-material support, .go prefabs that are never overwritten, and .collection scenes with grouped instances. It also supports optional convex collision export and texture copying into the Defold project. Version 0.5.2 adds color texture baking to PNG, including solid-color materials and complex node graphs such as Ucupaint, and handles objects with multiple material slots by exporting entries by material slot name.

Does Reforge overwrite existing .go files on re-export?

Reforge does not overwrite .go files on re-export, so manual components such as collisions and scripts remain intact. This supports repeatable pipelines where you re-export assets from Blender without losing work added on the Defold side. Version 0.5.2 also lets you export a single selected prototype, or update all prototypes, while keeping the existing .collection intact. Safe clear tools remove only exporter-created custom properties from objects and used materials, with a confirmation step before doing so.

Is Reforge free to use?

Reforge is listed as free here and is distributed under the GNU General Public License v3.0 or later. It does not require special permissions to run in Blender. For current licensing terms, source code, and issue reporting, check the developer's page and repository. The add-on is a compact download and installs either by dragging and dropping it into Blender or by installing it from disk through the extensions preferences.
