SPHLiquid is a UE4 plugin for SPH fluid simulation. The actual simulation is a UE4 port of Troy Zhai's awesome CUDA implementation of SPH fluid sim.
To run this plugin, please first build the forked branch. Remember to build the project as static library, not as executable file.
Then copy the build library under LiquidSimLib/lib/x64. Note that if you have changes in the interface files (FluidSystem.h, FluidParticles.h, FluidSolver.h), you will also need to copy them to overwrite counterparts under LiquidSimLib/include. https://www.youtube.com/watch?v=7ojILF1Dmro&t=0s
Finally, make changes to Build.cs file to make sure everything is referenced correctly.
