[OPEN-SOURCE] Machinery Modelling Toolkit

I am on Linux, and was able to turn MMT_Content in to a cpp project and get to compile…with 4.15 after adding these lines

template<>
struct TStructOpsTypeTraits<FSecondaryTickFunction> : public TStructOpsTypeTraitsBase
{
        enum
        {
                WithCopy = false
        };
};

to the bottom of Plugins/MMT/Source/MMT/Public/MMTSecondaryTick.h as per instructions in the Engine code its self.

File: /mnt/store/UnrealEngine/4.15/Engine/Source/Runtime/Engine/Classes/Engine/EngineBaseTypes.h
Line: 404

// It is unsafe to copy FTickFunctions and any subclasses of FTickFunction should specify the type trait WithCopy = false 

Is the performance because of issues in the plugin its self, being on Linux, or this change in the code?

I tried the MMT_Content_CPP download and had to make the same change but it crashed when I hit play in the editor.

Thank you! I’ll add this change into 4.15 version.
Performance issue might be coming from the multiple prototype actors in the main level. They are not optimized and some of them are throwing warnings into the log. I’m observing this since 4.13.
If you try latest version from github, it should work better as I’ve cleaned up main level.
