Redline MLO Detailed Room Model Builder

Build editable MLO interiors in Blender without spending hours manually creating basic walls, floors, room divisions, openings, frames, stairs, and trim.

The Redline MLO Detailed Room Model Builder is designed to handle the repetitive modelling stage of an MLO project. Define your working bounds, tag doors and windows, generate a room layout, customise each room, then convert everything into regular editable Blender meshes ready for your finishing work and Sollumz pipeline.

Streamlined Workflow

1. Select your exterior reference model.
2. Define the interior working bounds.
3. Tag existing doors, windows, and roller doors.
4. Generate the initial room layout.
5. Adjust each room and individual wall.
6. Add shared doors, windows, stairs, levels, frames, and trim.
7. Preview your materials and prepare DDS textures.
8. Apply all edits and convert the project into editable Blender geometry.
9. Complete your texturing, collisions, portals, room definitions, and game setup through Sollumz.

Built for Manual Finishing

The builder does not lock your project into a proprietary format. Once your design is applied, the generated components become regular Blender mesh objects.

You can continue working in Edit Mode to:

• Reshape walls and rooms
• Adjust topology
• Refine openings
• Add custom architectural details
• UV unwrap and texture
• Optimise geometry
• Prepare the project for your normal Sollumz export process

Requirements

• Windows
• Blender 4.5 LTS
• Basic Blender modelling knowledge
• Sollumz recommended for GTA V and FiveM preparation

Included

• Blender add-on installation ZIP
• Local DDS conversion tools
• Customer quick-start guide
• Full workflow documentation
• Known limitations document

Important Information

This add-on automates the bulk Blender modelling stage. It does not automatically configure every Sollumz room, portal, collision, archetype, entity set, YTYP file, or FiveM resource.

Final game preparation, optimisation, metadata, CodeWalker validation, and in-game testing remain the responsibility of the creator.
