H3Landscape

Plugin for the HoMM3 HD+ (Heroes of Might & Magic III patch)

Compatible with HoMM3 Complete edition, Horn of the Abyss 1.8.0 and ERA 3

About

This add-on makes the battlefield backgrounds better match the terrain on which the battle takes place (it adds a lot of new images of underground battlefields).
It also adjusts the appearance of certain objects on the adventure map to match the terrain they are located on.
All the changes that H3Landscape has made to the game are described on the wiki.

Download and installation

You can download the H3Landscape plugin installer from the Last release.
The installer H3Landscape.msi should automatically find the location of the installed “Heroes of Might & Magic III” game. If it does not, you have to specify the folder where the game is located.
After installing the plugin, run HD_Launcher.exe and add “Landscape” to the list of plugins.
To run Horn of the Abyss with the H3Landscape add-on, use the H3HotA_HD_L.exe file.

Build

To build the H3Landscape plugin, you need Microsoft Visual Studio 2022 or 2026 with the following components installed:

Component VS 2022 VS 2026
MSBuild required required
Windows Universal CRT SDK required required
MSVC ver 141 required optional
C++ Windows XP Support for VS 2017 (v141) tools required N/A
MSBuild support for LLVM (clang-cl) toolset optional required
C++ Clang compiler for Windows optional required

For VS 2026, you have to install Windows SDK version 7.1 separately. To do this, download the ISO image from the Microsoft website, and then install the following components:

  • Setup\WinSDKBuild\WinSDKBuild_x86.msi (headers and libraries),
  • Setup\WinSDKWin32Tools\WinSDKWin32Tools_x86.msi (tools).

The plugin and patcher for HotA can be compiled in several ways:

  • by opening the H3Landscape.slnf solution in Visual Studio 2026 (MSBuild + Clang-CL compiler)
  • by using the CMake tool with NMake Makefiles generator (NMake + Clang-CL compiler)
  • by using the CMake tool with Visual Studio generator (MSBuild + CL compiler)

You can build the MSI installer for H3Landscape in Visual Studio 2026 by opening the full solution H3Landscape.slnx.

If you want to build the plugin using CMake on Windows, it is recommended to install the Clang compiler, which is provided as a component of Visual Studio.

To generate project files using CMake, it is best to use the following command:

cmake -G "NMake Makefiles" <source dir>

(the NMake tool is part of the Microsoft Visual Studio package)

To build the Landscape.lod resource file, you need the mmarch.exe tool. If Visual Studio cannot find this tool during the build process, it will attempt to download it automatically.

H3Landscape uses the NH3API library, which is included in this project as a git submodule.
To download the NH3API submodule, after cloning the H3Landscape repository, you have to also execute the command:

git submodule update --init
