Blockbench Modeling
Lets you build 3D models in Blockbench through code, handling both Minecraft-style cube modeling and freeform mesh editing. You get tools for placing and modifying cubes with texture mapping, creating primitive meshes (spheres, cylinders), extruding faces, moving vertices, and organizing everything into bone hierarchies. The filtering tools are genuinely useful: find_elements_by_criteria lets you query by regex, type, parent group, or size without loading the full outline, and filter_by_material shows exactly which faces reference a texture. Good for programmatic model generation or batch edits. The workflow mirrors Blockbench's UI closely enough that you can translate manual steps into tool calls without much friction.

Blockbench Modeling
Build 3D models using cubes and meshes in Blockbench.
Plan the Shape and Target
Before a new model or substantial geometry redesign, resolve the user's appearance/accuracy, performance, or balanced preference through Blockbench use. Follow appearance and performance planning to set a working element/face budget and choose which details belong in geometry, UV tiles, or PBR. Prototype and count one repeated section before multiplying it; braces, infills, foot plates, and fasteners should not automatically become separate cubes.
Spend faces on silhouette, parallax, and deformation. Delete faces no required view or pose reveals, since real-time meshes need not be watertight. Let parts intersect instead of stitching edge loops around the joint, and float thin detail planes instead of cutting detail in. Keep geometry for recesses and openings whose depth must change as the camera moves. See real-time asset planning sections 4–6 for per-target budgets and face-removal rules.
