Version 1.2.0.0

Mesh Painter v1.2.0 — STL & PLY Export, PLY Import Fixes, Smoother Save/Exit

Biggest addition this update: STL and PLY export are now available (paid). Alongside existing OBJ/GLB export, you can save your painted meshes in four formats now.

Also squashed a nasty bug in PLY ASCII import — the reader was parsing header lines as garbage vertices on Windows (get_as_text() ignoring seek position + \r\n byte offsets). Now rock solid.

Full changelog:

New (paid):

• STL binary export
• PLY ASCII export (with vertex colors, normals, UVs)

Fixes:

• PLY ASCII reader rewritten — line-by-line parsing, correct byte offsets on Windows
• "Save & Quit" now handles all four formats (GLB, STL, PLY, OBJ)
• Export dialog filter updated to show all supported formats

Quality of life:

• "Last Session" simplified — no more Original File button, autosave only for unexpected quits
• Discard & Quit properly deletes autosave
• Manual save also updates autosave as safety net
• Help dialog now shows a format support table (which formats preserve colors/UVs)
• Version bumped to 1.2.0
