SC4 Plop and Paint is a DLL plugin for SimCity 4 that adds an in-game Advanced Plopping & Painting panel. It lets you browse your installed lots, plop lots directly, paint props and flora, create reusable weighted prop families, paint terrain decals, and quickly build detailed scenes without repeatedly hunting through menus or hand-placing every item. The plugin is aimed at players with large Plugins folders, city-detailing workflows, MMP-style flora work, prop-heavy scenes, and lot-testing setups. It includes a cache builder that scans your SC4 installation and Plugins folders, reads exemplar/cohort data, and generates searchable lot, prop, flora, decal, thumbnail, and family data for the in-game DLL. NOTE: This is a newer version compared to the last version that was available on the STEX before the Simtropolis reset! It now comes with prop/lot/flora picking functionality, better support for seasonal props AND texture painting! The GitHub release v0.9.1 with attestation and SHA256 checksums is available at https://github.com/caspervg/sc4-plop-and-paint/releases/tag/v0.9.1 Main features In-game Advanced Plopping & Painting window, opened with O by default Buildings & Lots browser for finding and plopping lots, including growables Props browser with thumbnails, favorites, scene picking, and paint mode Prop Families tab for built-in families and custom weighted random prop palettes Flora browser and Flora Collections for painting single flora, families, and multi-stage chains Decals tab for painting texture decals on terrain and lot surfaces Direct paint, line paint, and polygon fill modes Grid overlay, snapping, rotation, spacing, density, density variation, and preview controls Pending placement workflow with undo before committing Prop strip mode for removing placed city, lot, and street props Favorites and recent paint history for faster repeat workflows Seasonal thumbnails where supported by the source content Dependency SC4 Plop and Paint requires SC4RenderServices v0.6.2 or newer.

SC4PIM-X 2026 is a community-preserved and substantially expanded edition of @wouanagaine’s classic “better Maxis PIM and Lot Editor” for SimCity 4, originally released in 2009, also known as PIM-X or X-Tool. It can create building, prop, flora and foundation exemplars from SC4 models; create and edit growable or ploppable lots; manage building and prop families; inspect dependencies; and edit lots in an integrated 2D/3D workspace. The project began by recovering the original application from its compiled Python 2.4 bytecode. It has since grown far beyond a Python and OpenGL compatibility update. The familiar SC4PIM-X workflow remains, but its editing tools, rendering, performance and support for modern SC4 modding practices have been extensively expanded. Big changes Completely redesigned Lot Editor: The asset browser now supports searching, sorting, favorites, adjustable thumbnails and detailed hover information. Assets (props, flora, families, effects, textures, ...) can be searched by name, family member or source filename. The renewed editor also adds: Editable object position and rotation Alignment, centering, rotation and mirroring tools Configurable grid snapping Fit-to-lot and additional close-up zoom levels Layer visibility controls (i.e. temporarily turn on/off certain asset types to focus on others) Separate land and water placement constraints Better keyboard shortcuts and toolbar controls Persistent window layouts and column sizes Undo and redo in the Lot Editor: Lot editing is no longer a one-way process. Object placement, movement and other edits can be undone and redone, making complex lot work much safer and less frustrating. Timed, seasonal and animated prop previews: The Lot Editor preview system now understands more of what actually happens in-game. Date and time controls can be used to inspect timed and seasonal props, including playback and looping. Animated S3D and ATC models can be previewed and represented by animated thumbnails, while family variations can be inspected and selected directly. Day and night rendering in the Lot Editor (both Maxis night and SimFox DarkNite) Transit-enabled lot editing: The original release offered very limited support for transit-enabled lots. This edition adds a dedicated transit workflow with: Transit-object placement and inspection Edge-direction and edge-byte editing SC4Path discovery, parsing, previews and selection (i.e. the ability to assign custom paths to a TE tile) A structured Transit Switch Points editor Data-driven presets for common stations and transport combinations (thanks to @Tyberius06 for his wealth of knowledge on this!) Automatic calculation of relevant transit properties, costs and capacities Safer property / Filling Degree recomputation: Recomputing exemplar properties now opens a comparison showing what will be added, changed or removed. Individual changes can be selected before they are applied, helping preserve intentional manual overrides (i.e. OGs, etc.) and preventing unexpected bulk edits. Dedicated property editors: Several complex properties no longer have to be edited as opaque lists of numbers. Purpose-built editors are provided for areas such as: Occupant Groups and Occupant Type Transit Switch Points Building submenus Response curves Prop timing A new dependency report: The dependency dialog has been redesigned to find and clearly display all missing resources rather than stopping at an incomplete result. It understands additional resource types, and can use the SC4 Prop & Texture Catalog (thanks @nos.17 for providing this!) to provide more useful information about missing props and textures. Major loading and browsing improvements Additional improvements: Configurable SimCity 4 Plugins location High-DPI display support for crisper text and graphics for people with Retina or 4k monitors MacOS compatibility (experimental!) Numerous fixes for lot creation, exemplar values, models, textures, animations, ... Installation Extract the complete archive to a folder of your choice and run SC4PIM-X from there. On Windows, keep SC4PIMX.exe together with its accompanying _internal folder. The executable will not work correctly if it is copied out by itself. The packaged release is self-contained; users do not need to install Python separately. Settings, logs and generated caches are stored in: %APPDATA%\sc4pimx\ As with any modding utility, keep backups of files you intend to edit. This is a major reconstruction and expansion of an old application, so reproducible bug reports are welcome. Including the generated log will make problems much easier to investigate. Credits and provenance The original SC4PIM-X was created by wouanagaine in 2009. Its source was never published and was later lost. This edition was reconstructed from the surviving Python 2.4 bytecode and then modernized and expanded. The decompilation and modernization were carried out primarily using GitHub Copilot and Claude Code under human supervision and verification. Additional catalog entries and transit presets include community contributions by @Tyberius06. Thanks also go out to @Ulisse Wolf for maintaining and expanding the new_properties.xml file that SC4PIM-X relies on for accurate caclulation of property values for all kinds of buildings.

SC4 Terrain Extensions is a DLL plugin for SimCity 4 that adds in-game terrain editing and visualization tools. It lets you flatten terrain, create constant-grade paths, build bridge approaches, preview terrain changes, save and restore terrain snapshots (experimental), and display contour and slope overlays while working in a city. The plugin is aimed at players who do detailed terrain prep for roads, rails, bridges, canals, waterfronts, slopes, sunken networks, and city-detailing scenes. It is especially useful for diagonal work: the flatten tool includes a line-mask mode for diagonal cuts and ramps, while the constant-grade tool can create straight sloped paths between two dragged points. The GitHub release v0.1.0 with SHA256 checksums is available at: https://github.com/caspervg/sc4-terrain-extensions/releases/tag/v0.1.0 Main features In-game terrain menu buttons for Flatten, Constant Grade, and Bridge Approach tools Interactive drag-based terrain editing with live previews Diagonal and fractional flattening using line-mask mode Constant-grade paths for smooth ramps, roads, rails, canals, and terrain cuts Rectangle flattening for more precise terrain leveling Flatten modes for reference average, delta, explicit height, selected-area average, minimum, and maximum Bridge Approach tool for grading one or both ends of a bridge span, with adjustable bridge height, maximum grade, approach side, and approach width Terrain snapshot panel opened with the terrainsnap cheat (experimental). Allows to save, preview, restore, delete, and region-restore terrain snapshots Contour overlay with configurable interval, opacity, thickness, and major-line behavior Slope heatmap overlay with configurable slope mode, opacity, minimum grade, and color thresholds Dependency SC4 Terrain Extensions requires SC4RenderServices v0.6.2 or newer, which can be found at the GitHub link or from the STEX: Usage instructions Open a city and use the new terrain menu buttons. The instructions below might seem daunting at first but once you get used to it it becomes a blast to be able to detail terrain so accurately!

SC4 Render Services is a DLL plugin framework for SimCity 4 that adds shared rendering services for other DLL mods. It provides Dear ImGui UI support, DirectX 7 draw callbacks, S3D camera/world projection helpers, and terrain decal rendering APIs. Most players only need this if another DLL mod lists SC4RenderServices as a dependency. Modders can use it to add in-game tools, overlays, custom UI panels, terrain decals, and render-pass hooks without each mod needing to implement its own DirectX/ImGui integration. NOTE: This is a newer version compared to the last version that was available on the STEX before the Simtropolis reset! The GitHub release v0.6.3 with attestation and SHA256 checksums is available at https://github.com/caspervg/sc4-render-services/releases/tag/v0.6.3 System Requirements SimCity 4 version 1.1.641 (Digital Deluxe) Windows 10 or later DirectX/hardware rendering mode The plugin may work on older Windows versions with the Microsoft Visual C++ 2022 x86 Redistributable installed, but that has not been tested and is unsupported. Installation Close SimCity 4. Run the included installer. Select your SimCity 4 installation folder, the folder containing Apps. Select your SimCity 4 Plugins folder. Start SimCity 4. The installer places imgui.dll in the SimCity 4 Apps folder and SC4RenderServices.dll in your Plugins folder. If SC4RenderServices.ini does not already exist, a default copy is installed. Configuration The plugin reads optional settings from SC4RenderServices.ini in the same folder as SC4RenderServices.dll. Example: [SC4RenderServices] LogLevel=info Theme=dark UIScale=1.0 ShowDemoPanel=false EnableImGuiService=true EnableS3DCameraService=true EnableDrawService=true EnableTerrainDecalService=true EnableCustomTerrainDecalRenderer=true Most users can leave the default configuration unchanged. UIScale can be interesting for people running on high resolution monitors. 3rd party code gzcom-dll - GNU LGPL v2.1 Dear ImGui - MIT License mINI - MIT License spdlog - MIT License {fmt} - MIT License D3D7Imgui - see upstream repository for license details

SC4 Season Jumper is a DLL plugin for SimCity 4 that fast-forwards the city simulation to the start of a target season, then pauses the city automatically. It is designed for seasonal-flora workflows, consistent region-view screenshots, and other date-sensitive city-building tasks where you want the simulator to advance normally instead of forcing the date with the SC4ExtraCheatsDLL SimDate cheat (which can introduce bugs in the city statistics). The plugin is mainly aimed at players who use seasonal flora, seasonal props, detailed MMP scenes, or region-view presentation workflows. By letting the game run at its fastest speed until the target date, SC4 Season Jumper avoids the historical-stat issues that can happen when the date is changed directly. It also includes an enabled-by-default fix for a vanilla SimCity 4 bug where seasonal props created during their active season can stay invisible until the next time their start date comes around. The GitHub release v0.2.0 is available at: https://github.com/caspervg/sc4-season-jumper/releases/tag/v0.2.0 Project page: https://github.com/caspervg/sc4-season-jumper Main features Ctrl+F9 hotkey for jumping to the next useful seasonal date From January through August, Ctrl+F9 jumps to September 1 From September through December, Ctrl+F9 jumps to June 1 of the next year Automatically pauses the city when the target date is reached Press Ctrl+F9 again while a jump is running to cancel and pause immediately Cheat commands for jumping to specific seasons Fixes the seasonal prop visibility bug: covers painted props (from SC4Plop-and-Paint), plopped or grown lot props, and 3D prop previews Dependency No dependencies. System Requirements SimCity 4 version 1.1.641.x Windows version of SimCity 4 Microsoft Visual C++ 2015-2022 Redistributable x86 Installation Close SimCity 4. Copy the included files into your SimCity 4 Plugins root folder: SC4SeasonJumper.dll SC4SeasonJumper.ini SC4SeasonJumper.dat Start SimCity 4 and load a city. Press Ctrl+F9 to start a seasonal jump. Usage instructions Ctrl+F9: jump to the next fall start if the current date is January through August, or to the next summer start if the current date is September through December. Ctrl+F9 while jumping: cancel the jump and pause immediately. Cheat codes are available through the normal cheat dialog: jumpseason: same behavior as Ctrl+F9 jumpspring: jump to the next March 1 jumpsummer: jump to the next June 1 jumpfall: jump to the next September 1 jumpwinter: jump to the next December 1 Configuration The plugin reads settings from SC4SeasonJumper.ini in your Plugins folder. [SC4SeasonJumper] LogLevel=info LogToFile=true ; Fix the vanilla bug where seasonal props placed mid-season stay invisible ; until the next time their start date comes around (set to false to disable).
