ShaderFit

Client module for Blockland v21. It keeps the shadow map at a size this 32-bit game can allocate.

Place ShaderFit.dll in the game's modules folder, then quit and start Blockland from Steam. A DLL that is already loaded stays mapped until that restart.

The largest shadow map this build will use is 8192 with 4 cascades. 16384 is 2 GB and the game runs out of memory there, so that size is not used.

The DLL only changes rendering on this client.

Build

Blockland is a 32-bit program, so the DLL has to be built with a 32-bit MinGW toolchain (i686-w64-mingw32). Put that toolchain's bin directory first on PATH so CMake finds that gcc and mingw32-make.

find_package(TSFUNCS) needs a tsfuncs 1.0.1 package: tsfuncs-config.cmake next to include/ and lib/. MinHook's cmake package lives under that package's lib/minhook. Pass the package directory as CMAKE_PREFIX_PATH.

From this repo:

cmake -G "MinGW Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_POLICY_VERSION_MINIMUM=3.5 -DCMAKE_PREFIX_PATH=C:/path/to/tsfuncs -S . -B build
cmake --build build

The result is build/ShaderFit.dll. CMake is set so the filename has no lib prefix. The link line is tsfuncs, MinHook, psapi, opengl32, and dxgi, with static libgcc and libstdc++.

Source is src/main.cpp and CMakeLists.txt. The current DLL is attached to the v1.0.0 release.
