Connect Claude, Cursor, VS Code, or Codex to Layer’s MCP server and Trellis becomes a tool your agent can reach for — it picks the parameters, runs the generation, and shows you the result in the conversation.

Why use Trellis for 3D?
High accuracy 3D reconstruction with dense, clean geometry
Trellis produces structurally detailed meshes with well defined topology, stable proportions, and consistent geometry. It is ideal for capturing complex shapes such as creatures, characters, weapons, and hero props.
Advanced material and texture inference for engine ready assets
The model generates realistic material maps, convincing texture detail, and coherent lighting information. Trellis creates assets that import cleanly into Unity, Unreal, Blender, or Maya with minimal adjustment.
Strong consistency across stylized and realistic 3D styles
Trellis handles a wide range of aesthetics, from painterly stylized assets to physically based realism. This flexibility makes it useful for game studios building hybrid pipelines for UA assets, prototypes, or LiveOps content.
High fidelity 3D assets for trailers, cinematics, and promotional renders
Create premium hero objects, creatures, or characters with rich material detail. Trellis supports cinematic shots, marketing renders, and top tier UA creatives that require visual polish.
Accurate 3D reconstruction from reference images for rapid production
Turn concept art, reference photos, or in game art into clean meshes suitable for downstream editing. Trellis accelerates prototyping, iteration, and asset creation without sacrificing quality.
Consistent 3D asset packs for LiveOps events and seasonal content
Produce theme matched sets of weapons, interactables, collectibles, and environment pieces. Trellis maintains visual coherence across multiple assets, making it strong for frequent LiveOps drops and content refreshes.
FAQ
How much does Trellis cost? Is it free?+
How does Layer's pricing work?+
There are no seat fees, feature gates, or plans on Layer. Instead, our platform uses a consumption based system with Creative Units (CUs) with a flexible monthly subscription. Every generation on Layer (image, video, 3D, or audio) consumes a Creative Unit, and you only pay for what you create.
