I download HairWorks branch of UE4 from GitHub.
The project runs correct after I built engine source.
Then I import my own .apx or . apb files which is exported from HairWorks_1_0_Viewer, but editor report “Failed to import…Failed to create asset…” like this message.
I try to trace source code and find GApexSDK return Serializer as none.
Do I miss any key point during the process when create or import the content?
