From a0355c9b897281d0bfea48bec9d490724ecabd96 Mon Sep 17 00:00:00 2001 From: SulfurNitride Date: Sun, 12 Apr 2026 17:54:45 -0500 Subject: Add NIF previewer plugin with Linux-specific fixes Vendored from github.com/Parapets/mo2-preview_nif and adapted for Linux: - BSA texture resolution via MO2 virtual tree with case-insensitive fallback walk (Linux FS is case-sensitive; NIFs reference textures with arbitrary case against files on disk) - Process-wide cached BSA candidate list, keyed by profile path, priority-sorted, filtering disabled mods - Path backslash normalization before loose-file lookup - Polygon offset on SLSF1_Decal-flagged shapes to break z-ties with coincident base meshes (road decals, moss overlays) - Opaque framebuffer via glColorMask alpha lock so alpha-blended shapes can't bleed the dialog background through the preview area - QMouseEvent::globalPosition().toPoint() for Qt6 compatibility Preview dialog behavior (organizercore.cpp): - Switch previewFile and previewFileWithAlternatives from stack-allocated exec() to heap + ApplicationModal + show() + WA_DeleteOnClose. - Parent passed as nullptr so preview lifetime is decoupled from the stack-allocated ModInfoDialog that spawns it. Nested exec() inside the enclosing dialog's exec() was softlocking on close.
