About the Model Inspector
Model Inspector is a free online GLB, glTF and OBJ viewer that also checks your asset. It counts triangles, vertices, meshes, materials, textures and animations, shows real-world dimensions, and flags common problems: missing UVs, missing textures, non-power-of-two or oversized textures, very high polycounts and suspicious scale. Switch between shaded, wireframe, normals and UV checker views, then download a text report to share with your team or client.
FAQ
Which formats are supported?
.glb, .gltf (drop the .bin and texture files together with it) and .obj (with its .mtl and textures).
How is the triangle count calculated?
From the actual mesh geometry after loading, including every mesh in the file; quads in OBJ files are counted as two triangles.
Is my model uploaded?
No. Everything runs locally in your browser with WebGL; your files are never uploaded to a server.
