Benchmarking Trellis 2: GLB Output Quality Across Six Input Types
Everyone shows off AI image-to-3D with the same glossy product render on a white background. That tells you almost nothing about how the tool behaves on your input. So I ran a proper bake-off: one model — Trellis 2 , the SLAT-based image-to-3D generator — fed six deliberately different input types, all judged on the output that actually matters to devs: the GLB you import into your engine. The…
A rigorous head-to-head test of AI image-to-3D generator Trellis 2 revealed surprising results across six unique input types, each judged primarily on the quality of the resulting GLB file useful for game development.
The studio product shot, featuring a clean white background, served as the benchmark, yielding flawless results with a perfect 10/10 score. An amateur phone photo of a cluttered desk yielded surprisingly good outcomes, with the model effectively ignoring the distracting clutter and delivering usable results for background props with minimal cleanup, scoring 8/10.
The stylized concept art input proved to be Trellis 2's strength, producing a mesh that matched the artistic intent and genre, earning a 9/10 score. However, for low-poly screenshots from game development, the output often inherited the angularities of the source, resulting in a 7/10 score.
Sketches, although challenging, produced charming concept models that were useful for pre-visualizing ideas, earning a 9/10 score for ideation work and a slightly lower 6/10 for finished assets. Multi-view collages, however, confused the reconstruction process, scoring only 4/10.
Practical takeaways emphasized that the best input scenarios involve clean silhouettes, a single dominant view, and honest lighting conditions. The resulting GLB files imported cleanly every time, although the output meshes were dense and would likely require decimation for mobile targets. Generation times remained consistently between 1-3 minutes in the cloud-based browser environment.
For game developers seeking efficient asset creation, the optimal approach involves using real-world reference photos or concept art. These inputs cover roughly 80% of the typical "I need a prop by Friday" scenarios and provide reliable results, though some manual back-side cleanup may still be necessary for hero assets. Overall, Trellis 2 emerges as a promising image-to-3D tool that can handle common production workflows more effectively than previous methods.
