How to enable Clothing on Android Device


1, Enable bCompileNvCloth in source file UEBuildAndroid.cs:

Target.bCompileNvCloth = true;

Source path:

2, Add NvCloth module in .Build.cs.

using UnrealBuildTool;

public class TestTP2 : ModuleRules
    public TestTP2(ReadOnlyTargetRules Target) : base(Target)
        PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;

        PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "NvCloth" });
