ProcTHOR house sources

These 100 homes use the official MolmoSpaces conversion of ProcTHOR test houses 0–99. Explore their rooms and articulated objects in the browser. The viewer does not run a navigation policy or live physics.

What the evidence establishes

All 100 converted scenes compile in MuJoCo 3.5.0. Their native references contain 21,229 body frames, 25,156 group-0 visual shapes and 6,520 joints, including free joints. House 0 has 294 visual shapes, 19 scalar joints and 49 free object bodies. Browser body frames are compared with the converted native scenes. Compilation, rendering and joint inspection are not successful task execution.

The archive's input house JSON matches the original ProcTHOR test house 0. Converted geometry and object placement differ from AI2-THOR 5.0.0: a separate surface-bounds comparison found 61 of 75 comparable object assemblies within 1 cm, with fourteen farther apart. Two CD native captures contained no vertices. This conversion does not establish identical simulator dynamics.

The asset lock covers 18,000 selected files across 100 distinct scene XMLs. Shared object assets are stored once. File counts, object instances and room counts are not additional worlds. No robot model, Gym task, evaluation score or successful trajectory is attributed to these scenes.
