Licensing
How the open Blender-side code, separately licensed Unreal payloads and local Gumroad bridge activation fit together.
License split
The codebase deliberately separates the Blender-side add-on from the Unreal-side payload:
| Part | License |
|---|---|
| Blender-side add-on code | GNU General Public License v3.0 or later (GPL-3.0-or-later). |
Unreal/ Python payloads | Separately licensed proprietary commercial software. Purchasers may use the payloads in personal/commercial projects but may not redistribute the original or modified files. |
Activation behavior
The local Bridge activation uses a Gumroad purchase key. According to the current 1.0.0 implementation/readme:
- Gumroad is contacted only when Enable License is clicked.
- After successful activation, subsequent use works offline.
- There is no recurring online license check.
- There is no activation-count limit in the current implementation.
Without activation
Unreal instance discovery/selection is disabled without activation. Blender-side asset export and placement-data writing remain available, as do the ordinary structure, LOD, collision, material and texture tools.
