Crash on selecting Instanced Static Mesh component in 3D view

Development Programming & Scripting
1

Hi,

I’ve been able to reproduce the following bug on a clean project:

  1. Create a new BP with a Instanced Static Mesh Component.
  2. Choose e.g. the shape_cube default asset as static mesh of the component.
  3. Add an instance to it in the Construction Script (with the Add Instance node).
  4. Compile the BP: The mesh instance appears.
  5. Click on the ISM Component in the Components tab of the BP in the 3D view (i.e. simply click on the mesh instance): CRASH.

The console in Visual says:

D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.1\Engine\Source\Editor\Kismet\Private\InstancedStaticMeshSCSEditorCustomization.cpp(35): Assertion failed: InHitProxy->IsA(HInstancedStaticMeshInstance::StaticGetType())

I hope somebody can reproduce this as well.
