Mesh Disappears while setting Mesh Variation

Mesh Disappears while setting Mesh Variation

Bug

The mesh disappears when linked to the Variation Actor or the Mesh Variation Type is set to other than Disabled.

This is because the Actor World Transform isn't set in the variation actor. The mesh is therefor moved to position 0,0,0.

Work Around

Copy the mesh's Transform into the variation actor's Actor World Transform before linking the mesh to the variation actor.
