Blueprinted voxel lod volume causes errors and crashes

[deanvaessen]

When blueprinting the voxel lod volume class, errors pop u p coplaiming about a collision component with 0 radius, and the blueprint child class not being compileable.

Seems to be related to the fact that the brush settings shape is none by default in the child.

The blueprint fails to compile without a shape set, and actually setting the shape in the blueprint causes a crash:

Assertion failed: InWorld != nullptr [Engine/Source/Editor/UnrealEd/Private/EditorBrushBuilder.cpp] [Line: 52]
