Hi, I’ve been using splines in a project for some time with a track based on the Kart Racer Template.

I just started creating a blueprint function using spline functions like this one: https://forums.unrealengine.com/filedata/fetch?id=1122235&d=1485739091

I created a new PlayerState C++ class, closed UE, and cannot reopen my project.

// D:\Engine\Source\Runtime\Landscape\Private\Materials\MaterialExpressionLandscapeVisibilityMask.cpp
UObject* UMaterialExpressionLandscapeVisibilityMask::GetReferencedTexture() const
{
    // Exception thrown at 0x00007FFA333868DA (UE4Editor-Landscape.dll) in UE4Editor.exe: 0xC0000005: Access violation reading location 0x0000000000000970. occurred
	return GEngine->WeightMapPlaceholderTexture;
}

Suggestions? Why is GEngine invalid/null?
