GC Merger is a script for 3ds Max from MastaMan that brings 3D models from the Great Catalog site into your scene. Rather than downloading and unzipping files or preparing a model before merging it, you browse the catalog, add models to Favorites, and see your collection inside the 3ds Max window.
The workflow centers on a single Download button. Press it, and after a few seconds the 3D model appears in the scene. Models arrive with correct names for the model, materials, and textures, along with all necessary textures and assets. The script leaves out useless layers, helpers, and light sources, avoids bringing garbage into your scene, and keeps the scene from slowing down after models are added.
Installation is handled by dragging the GC Merger.mzp file onto the viewport, or through the Scripting menu using Run Script. You can add a toolbar button via Customize User Interface under the GreatCatalog category. On first run, the script asks for an API key, which you generate in your profile on the Great Catalog site.
