I am new to Unreal, so I am not completely sure about how to fix it. It is the 2.0 release, and I will test on 4.13.2 too, later... I hope it can be fixed for 4.15.0

[rongcuid]

4.13 builds fine, so it is probably not my computer configuration problem. I guess the engine changes somewhat between the versions?

[WiggleWizard]

Pull down the latest branch, there's a fix for 4.15 in there

[rongcuid]

OK, now it works. Thank you.

Now I tried to make a simple mesh via this:

    TArray<FVector> Vertices;
    TArray<int32> Triangles;

    Vertices.Add(FVector(0, 0, 0));
    Vertices.Add(FVector(0, 100, 0));
    Vertices.Add(FVector(100, 100, 0));
    Vertices.Add(FVector(100, 0, 0));

    Triangles.Add(0);
    Triangles.Add(1);
    Triangles.Add(2);
    Triangles.Add(1);
    Triangles.Add(2);
    Triangles.Add(3);

    RuntimeMesh->CreateMeshSection(0, Vertices, Triangles, true, EUpdateFrequency::Average, ESectionUpdateFlags::CalculateNormalTangent);

However, I get the following error:

I suspect this is another version update error. I can't find related information about TypeInfo on the engine API, but I will test on 4.13 too.

[rongcuid]

4.13 also does not work. So it is probably my part.

[WiggleWizard]

@Koderz I think this is closed now 👍

[rongcuid]

When would you consider releasing to Marketplace? Though I have no problem including it in game projects separately.

BTW, I have to say that the documentations are a little difficult to understand. Also, blueprints really slows down the editor.

[Koderz]

A little late but This has been published to the marketplace now.

I'm aware of the docs but don't have the time right now unfortunately to really update them and with v3 being a large overhaul I'll probably wait and try to update them for that.

[blakeanator]

I'm having this exact same issue. I'm on 4.16.2 and have the latest RMC. What's the best way to solve this? Also, oddly enough, I downloaded your sample project and run into the exact same error. Maybe it's a problem with my computer? Thanks for the help!
