Sollumz

Sollumz is an open-source Blender add-on (under GNU license) developed by Skylumz, Colton Fox, and Alexguirre. https://github.com/Sollumz/Sollumz. This add-on will allow us to open and export 3D models in the proprietary format used by GTA V. Here are two options to install this add-on.

1. Once Blender is launched, go to Edit > Preferences > Get extensions

2. In Get Extensions > Repositories, click on the small "+" on the right, then on Add Remote Repositories and copy the link https://repo.sollumz.org/ into URL (found on https://docs.sollumz.org/getting-started/installation. Then, click on Create.

3. Click on Allow Online Access

4. Search for Sollumz in the extensions search bar and install Sollumz and Sollumz development (not Sollumz RDR development)

5. Go to Add-ons and check that Sollumz is well checked.

6. Install the necessary dependencies.

7. A new menu should be available in the right bar of the 3D view (activable with the n key if it is not visible).
