PMX Viewer for Windows

Inspect PMX character models

Tridi Viewer opens .pmx files locally on Windows. Use it to review supported character geometry, materials, bones, skinning, and morph targets in a real-time viewport.

PMX is associated with MikuMikuDance character workflows and can combine a mesh with material assignments, a bone hierarchy, skinning weights, and multiple morph categories. Tridi Viewer treats the file as an inspectable model asset; it does not emulate the complete MMD runtime or editing environment.

Common PMX viewing use cases

• Review character proportions, orientation, surface appearance, and mesh topology.
• Check whether material slots and local textures resolve after moving or unpacking a model.
• Inspect the imported bone hierarchy, skinning, vertex morphs, and supported group morphs.
• Use UV, wireframe, and render-pass views to diagnose deformation or shading issues.

Supported PMX data

• Polygon geometry, materials, local textures, and source topology.
• Bone hierarchy and supported skinning data.
• Vertex morphs and supported group morphs.
• Object, material, UV, wireframe, and render-pass inspection.

Textures, morphs, and motion files

Keep the PMX file and its texture folders together because material references normally depend on local files. If a character appears untextured, inspect the material and texture lists and confirm that the referenced paths survived extraction, renaming, or transfer.

A PMX model and VMD motion are separate assets. Tridi Viewer does not load external VMD motion, so opening a rigged PMX file does not automatically provide a dance or motion clip. Supported morph data can still be inspected as part of the model, but runtime behavior may differ from MMD-specific tools.

PMX support boundaries

Bone, UV, material, flip, and impulse morphs are not implemented. Unsupported morphs are omitted while usable model data remains available. MMD-specific physics, constraints, toon-shading behavior, external motion, camera data, and application-specific rendering should be verified in a dedicated MMD workflow.

For general diagnosis, compare the Objects, Materials, UV View, Solid Wireframe, and render-pass panels. A correct static preview confirms only the subset imported by Tridi Viewer; it does not certify identical appearance or motion in every PMX-compatible application.
