SC4 Render Services DLL  v0.6.3

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.
