Joxblox

Joxblox is a cross-platform Fyne desktop app for exploring Roblox assets, scanning files and places for asset references, and working with the results in a desktop UI.

Features

Tabs:

• Report Generation: grade an .rbxl/.rbxm against a chosen asset type (Map / Vehicle), with per-cell avg/p90/max breakdowns for spatial scenes and drill-in views for mismatched PBR materials, oversized textures, and duplicate uploads
• Single Asset: inspect a Roblox asset, preview supported content, browse child references, and view raw response data
• Scan: scan folders or .rbxl/.rbxm files, diff results, filter/search rows, preview, and save/load JSON result sets
• Heatmap: turn .rbxl/.rbxm asset references into weighted top-down map views with diff support and per-cell breakdowns
• 3D Heatmap: heatmap a single model asset by mesh part with full 3D camera controls
• LOD Viewer: inspect a mesh's LOD levels side-by-side
• Optimize Assets: find large image usage in a place file, filter candidates, resize them, and optionally upload replacements
• Image Generator: generate PNG images in bulk and optionally upload them through Roblox Open Cloud
• RenderDoc: import RDC captures, aggregate textures across captures, and inspect mesh / material / texture state

Other app features:

• Mesh preview support for model assets, with shaded / lit-clay / normals / unlit modes
• Drag-and-drop file and JSON-result importing
• Optional authenticated Roblox requests using .ROBLOSECURITY
• Embedded changelog and license info in release builds
