Changelog

All notable changes to Proto Previewer, newest first.

v1.0.0

Initial release

• Browser-based mesh viewer. Loads .glb directly and converts .obj and .fbx on import, keeping material slots, names, and UVs. Everything runs client-side; nothing is uploaded.
• Sixteen inspector modes — final and raw render, ten isolated material channels, plus matcap, wireframe, and a UV checker.
• Per-material texture overrides across ten channels, each with a 0–1 strength control, and a per-material Flip Y for moving normal maps between the OpenGL and DirectX conventions.
• Filename-sorted texture drops. A folder of maps lands on the right materials by name, tolerant of prefixes, separators, case, leading mesh names, and trailing size tags.
• Camera tool with 10–120° FOV, aspect presets from 2.39:1 scope to 9:16 portrait, rule-of-thirds and diagonal guides, and captures up to 1920×1080 with a transparent background.
• Camera presets storing pose, projection, FOV, and frame, so a shot can be reproduced exactly across a set of models.
• Seven lighting environments with orientation and brightness control, plus ground shadows, screen-space ambient occlusion, bloom, and vignette.
• Custom background image with anchor, scale, and height-relative offset, so it holds its position relative to the model when the window resizes.
• Local persistence. Model, textures, settings, and camera presets are kept in the browser and survive a reload.
• Mobile layout, with the two heaviest post passes off by default to protect the framerate.
