Building a game asset pipeline with AI generation in Japan

The question most game studios ask when they first look at AI 3D generation is not 'can it make assets' but 'can it make assets that fit into what we already have'. The answer depends almost entirely on how the output is structured, not on the quality of the geometry itself.

The naming convention problem

Most game asset pipelines have a naming convention that encodes information about the asset: type, LOD level, material variant, and sometimes the target platform. An AI generation tool that delivers files named 'output_001.obj' creates a manual renaming step that compounds across hundreds of assets.

Silver Canyon's batch pipeline accepts a naming prefix and a numbering scheme as part of the batch configuration. If your convention is ENV_PROP_ROCK_LOD0, you set that prefix once and every asset in the batch arrives named correctly. It is a small thing but it removes a step that otherwise happens manually at the end of a long day.

LOD generation and polygon budgets

Real-time game engines need multiple LOD levels for each asset. The base mesh is used up close; lower-polygon versions replace it at distance. Generating LODs manually from an AI-produced base mesh is straightforward but time-consuming at scale.

The Production plan includes automatic LOD generation at 50% and 25% of the base polygon count. The reduction algorithm preserves silhouette edges and UV seam positions, which means the lower LOD levels do not introduce visible texture stretching at the seam boundaries. For mobile targets, you can request a custom polygon budget in the batch settings.

Handoff to the engine

The cleanest handoff workflow we have seen from studios in Japan involves exporting FBX from the agent, importing into a staging scene in the target engine, and running the engine's built-in LOD validation before committing assets to the main project. This catches any import-time issues before they propagate.

For Unity projects, the FBX import settings that work consistently are: scale factor 1.0, normals calculated, tangents calculated, and smoothing angle 60 degrees. For Unreal Engine 5, the default import settings work for most assets, but enabling 'Generate Lightmap UVs' at import saves a step later in the lighting pipeline.

The studios that get the most out of AI generation are the ones that treat it as a pipeline component rather than a standalone tool. The output needs to fit the system, and the system needs to be set up to receive it.
