Model coverage and boundaries

478,110 web triangles; 52 supplied geometry groups before runtime flattening. Generic mesh chunks are not physical components. A project reconstruction with incomplete coverage, not a measured intact monument. Tetrapylon is one quarter only; project documentation reports 50% coverage for Tetrapylon and 40% for the Arch. Official #NEWPALMYRA Sketchfab upload.

Evidence & model coverage

Changes: Texture cap 512px (JPEG 85 for opaque images, PNG for transparency); duplicate/unused data removed; welded vertices; error-bounded simplification (0.001 relative tolerance; borders may change); Draco encoding; supplied mesh-bearing nodes retained. Legacy KHR_materials_pbrSpecularGlossiness converted to supported metallic/roughness PBR, including supplied diffuse textures; no replacement imagery.

It is one quarter section, not the entire Tetrapylon.

NEWPALMYRA’s Tetrapylon page marks its model incomplete, 50% documented, and its physical-site status text should not be repeated without separate current verification.
