BlenderGym: Benchmarking Foundational Model Systems for Graphics Editing

Figure 1 . Example task instances of BlenderGym, a 3D graphics benchmark that tasks VLMs with 3D scene reconstruction through code editing. BlenderGym consists of 245 handcrafted start-goal scene pairs across five key graphics editing tasks: object placement, lighting adjustment, procedural material editing, blend shape manipulation, and procedural geometry editing.
