This is a UE4 plugin that can create ghost mesh in Unreal Engine 4.
Default Version: 4.10.
For other Unreal Engine version, please check out the branches.
Just put the GhostMesh folder in the Plugins folder in your project. If there is no such a folder, create one.
Please check out the tutorial.
Actually I am not satisfied with current method to generate ghost mesh, because each ghost mesh still contains a skeleton.
I am considering to generate a static mesh for performance.
