Release 3.17.0 · fernandotonon/QtMeshEditor

Scene lighting epic (#482–#487, PR #803)

Full in-editor light authoring with preset rigs, viewport gizmos, and Inspector controls:

Six preset rigs: single key, three-point studio, outdoor sunset, outdoor overcast, indoor window, product turntable
Create / duplicate / delete point, spot, and directional lights from the toolbar, View menu, and scene tree
Light icons + gizmos in the viewport (toggle via View menu); pick lights in Select mode
Inspector panel: per-light diffuse/specular, intensity, attenuation, spot cone, cast-shadows toggle
Scene lighting section: ambient colour, rig preset picker, HDRI pairing (studio/overcast/sunset/window presets auto-load matching bundled HDRIs)
Undo/redo for light property edits, rig apply (including HDRI + rig-group membership), and light creation/deletion
CLI/MCP parity: light rig presets surface through the existing material/env tooling where applicable

Major quality upgrade for qtmesh anim --generate:

47-clip motion library with per-action variety (walk/run/jump/dance/march/kick/punch/wave/climb/idle + synonyms)
Retrained t2m ONNX model (library v4) with active-window sampling and best-of-N candidate selection
Retarget fixes for auto-rigged / −Z-facing meshes, calmest-frame reference pose, and 6D rotation packing
Inspector animation checkboxes refresh after generate; repeat generates stay on the rig skeleton

PBR generation no longer darkens surfaces — metallic/roughness FFP wiring corrected; tangents built before RTSS normal-map application
Spec-gloss slot wiring preserved; only metallic-roughness path goes inert on legacy FFP materials
