From d490363b61265847aa11555d055d8fc05ed292f8 Mon Sep 17 00:00:00 2001 From: the-e Date: Thu, 30 Jul 2026 14:43:00 +0200 Subject: [PATCH 1/7] Size qtFRED's post-processing targets for its resizable viewport The offscreen render targets that back post-processing -- the scene textures and the post-processing surfaces -- are allocated once from gr_screen.max_w/max_h at renderer init and never resized. The game never notices, because its window size is fixed after gr_init(). qtFRED does: FredRenderer::render_frame() calls gr_screen_resize() every frame to match a dockable, resizable widget, so growing the viewport past the startup size clipped the render to the old, smaller texture and then stretched it back over the new, larger viewport. Add Gr_min_render_target_w/h as a floor those allocations respect, and have qtFRED set it to the largest size its viewport can reach (the biggest screen the window could be maximized onto, in device pixels) before calling gr_init(). Left at 0 for the game, which keeps sizing them purely from gr_screen. That makes Scene_texture_u_scale/v_scale meaningful outside the game for the first time, which turns up two latent bugs: - Seven post-processing passes passed Scene_texture_u_scale for both axes. Harmless while the scene texture matches the screen exactly (u == v), wrong the moment it doesn't. - The bloom bright pass hardcoded 1.0/1.0. Unlike the passes after it, it reads the scene texture directly rather than an already-cropped intermediate, so it has to confine itself to the sub-rectangle that was actually rendered into. Finally, expose the pipeline in qtFRED at all: a View menu toggle brackets the 3D scene in gr_scene_texture_begin/end, the same way game_render_frame() brackets its own. Off by default, and it covers only the 3D world content -- the 2D overlays stay outside it.

Enable post-processing in the viewportRoutes the 3D viewport through + the game's HDR post-processing pipeline (bloom, tonemapping, lightshafts) instead + of drawing straight to the screen. Off by default. Every other setting on this tab + only has a visible effect while this is on.
Shadow qualityQuality of the shadows cast by the mission's sun in the + viewport.
Anti-aliasingPost-process anti-aliasing mode (FXAA/SMAA) used in the + viewport.
MSAAMultisample anti-aliasing for the viewport's 3D scene. Requires + restarting QtFRED to take effect.
Texture filteringMipmap filtering used for textures (bilinear or + trilinear). Requires restarting QtFRED to take effect.
Anisotropic filteringAnisotropic texture filtering level, up to the + maximum the current GPU supports. Requires restarting QtFRED to take + effect.
GammaBrightness of the viewport. QtFRED defaults this higher than the + game, since the viewport isn't normally tonemapped unless post-processing is + on.

That option's default_func returns GL_mipmap_filter itself, so with no persisted "Graphics.TextureFilter" value getValue() fell through to a still-zero-initialized global -- bilinear, where the config default is trilinear. Since in-game options are on by default, that affected every player who had never explicitly set the option, and it ignored the legacy TextureFilter key existing installs were configured through. Seed from config first, then let the option override, matching the order the anisotropy setting below already uses (its default_func queries the hardware directly, which is why it was never affected). Also route the option's value enumerator through the new shared gr_get_supported_anisotropy_levels() rather than a private copy.

Anything drawn while gr_screen was larger got clipped to their edge and stretched back over the viewport. The game hits this on the SDL window-resize path (osapi.cpp calls gr_screen_resize()); qtFRED hits it constantly, since its 3D viewport is a resizable dock widget. Add gf_resize_render_targets, called from gr_screen_resize(), and implement it for OpenGL: grow the targets to cover the new gr_screen, rebuilding only the resolution-dependent resources. The post-processing table, the compiled shaders and the SMAA lookup textures are resolution-independent and stay alive, which is what makes this cheap enough to run off a window drag. This mirrors what the Vulkan backend already does in VulkanPostProcessor::resize(); Vulkan leaves the hook unset because recreateSwapChain() owns it there. The allocation only ever grows: gr_screen_resize() is called every frame by qtFRED and repeatedly by the briefing map widget, so tracking the high-water mark avoids thrashing, and the shrunk state is already handled by Scene_texture_u_scale/v_scale. The size is also clamped to the hardware limit up front, so a viewport past that limit stops asking to be resized instead of rebuilding every frame. If the larger allocation fails outright -- most likely precisely when growing -- the resize stops before rebuilding the post-processing targets on top of scene textures that no longer exist. This replaces Gr_min_render_target_w/h, which sized the targets for the largest attached display up front -- on a 4K display at 2x scaling that was over a gigabyte of VRAM, allocated at launch, for a feature that is off by default and may never be switched on. Deletions now go through GL_state.Texture.Delete(): a freed texture name the state cache still holds would make a later Enable() of the recycled name a silent no-op. This mattered little when teardown only ran at shutdown. While there, the scene teardown now releases everything setup allocates -- it was leaking Scene_ldr/composite/luminance/Cockpit_depth and all six MSAA targets -- and post-processing shutdown releases the SMAA lookup textures. Separately, fix the sampling extents that the above makes reachable: - deferred-f.sdr turns gl_FragCoord into a G-buffer coordinate using invScreenWidth/Height, which described gr_screen rather than the G-buffer. Fixed in both backends; it is currently a no-op under Vulkan, where resize() keeps the extent equal to gr_screen, but states the requirement instead of relying on that. - the MSAA scene-colour copy, the MSAA resolve and the fog pass sampled the full [0,1] range of targets that are only filled to the u/v scale. - fxaa-v.sdr derived its texcoord from vertPosition, ignoring the sub-rectangle the draw call asked for. Those extents now come from opengl_draw_full_screen_scene_texture() rather than being open-coded, so a new pass cannot quietly reintroduce the bug. The volumetric nebula pass is deliberately left unscaled and commented: it uses fragTexCoord both to reconstruct a ray direction and to sample, which needs a shader change to separate.

The split between settings that apply live and settings that need a restart was recorded only in comments that had to stay in sync across five files. Move both into GraphicsSettings, which owns the keys, the defaults, and the two apply paths (applyLive() and applyBeforeGrInit()). ViewSettings holds one of these instead of seven loose fields. Behaviour fixes that fall out of having one reader: - Values are range-checked before being cast to ShadowQuality/AntiAliasMode and validated against the MSAA list, matching what the neighbouring DataMenuStyle load already did. A hand-edited settings file no longer produces an out-of-range enum. - The two OptionsManager overrides are now consistent. Texture filtering was overridden unconditionally with a hardcoded default while anisotropy was guarded, so a fresh install masked the engine's own texture-filter default for no reason. Both now use a sentinel for "the user has not chosen" and leave the engine option alone until there is a real choice. - gr_set_gamma(3.0f) is no longer duplicated as a literal next to the struct default. The dialog's value lists now come from the engine option definitions (Graphics.Shadows, Graphics.AAMode, Graphics.TextureFilter) instead of the hardcoded .ui items that duplicated them, and anisotropy uses the shared gr_get_supported_anisotropy_levels() rather than a near-verbatim copy of the engine's enumerator. Adding an AA mode upstream no longer silently desyncs qtFRED's dropdown. Note that the shadow-quality entries therefore lose the "(restart required)" suffix they carried in the .ui; the control's tooltip and the help page still say it. Populating combos now blocks signals: setupUi() has already run connectSlotsByName(), so filling them would otherwise fire the change slots and mark the model modified before the user touched anything. Finally, render_frame() gets its three correlated EnablePostProcessing branches replaced by a scoped ScenePostProcessing guard, and the shadow pass -- with the HTL matrix-stack dance it needs -- moves into its own named function.

It is a stale duplicate of general/PreferencesDialog.html -- the page the table of contents, the Preferences keyword, and Viewport.html all point at -- and one of only two orphaned files under help-src/doc. None of the new documentation reached the Help viewer. Document the tab on the page that actually ships, and revert the edit to the orphan so nothing is left stranded there. The orphan itself predates this branch and is left alone; it should probably be deleted, but that is a separate question from this branch. The content is also corrected against what the settings now do: - Shadow quality requires a restart. The orphan did not say so, and the dropdown entries no longer carry a "(restart required)" suffix now that their labels come from the engine's own option definition. - Texture filtering and anisotropy default to the engine's own choice (the config default, and the hardware maximum) until the user picks one. - Anisotropy is disabled outright on hardware that does not support it. - Gamma documents its actual range and default. - The page's "changes take effect immediately" claim is qualified, since it is not true of the four restart-only settings. Also notes the View > Enable Post Processing menu equivalent, which had no documentation anywhere -- no help page covers the View menu's display toggles.

Rewrite it around gf_resize_render_targets, and keep the two failed attempts as history, because the reason they failed is the reason the current one works. That document had already identified the prerequisite correctly: the scene teardown left FBOs attached to stale texture handles, and draws to an incomplete FBO go nowhere, hence the black viewport. Completing the teardown was what made reallocation viable. Also records the two properties that are easy to get wrong (clamp to the hardware limit before deciding whether to resize, or a viewport past that limit rebuilds every frame; never resize mid-frame), the sites fixed in the deferred and Vulkan paths, and why the volumetric nebula pass is deliberately left unscaled. Corrections to the Preferences help page from the same review: - Enabling post-processing does not by itself produce shadows. Shadow quality defaults to Disabled and needs a restart to change, so the page said the opposite of what a user will experience. - The anisotropy control also greys out when the GPU reports a maximum of 2x, not only when it lacks the feature outright. The help keyword index is left alone: keywords there are page-level, with multiple entries only ever used as synonyms for one page, so per-setting keywords would be inventing a convention rather than following one. Finally, note in the qtfred module guide that its viewport calls gr_screen_resize() every frame -- the assumption whose violation caused all of the above -- and where the graphics preferences now live.
