Dear Friends at Epic,
#Asset on Dropbox
NathanLyer/cube256.apb
This asset was made in Physics Lab and I set an inner material so I could have the inside of the mesh fractures be very distinct from the outer surface material.
I did this all the time in Nov2012 UDK and even made some Unrealscript functions to have an option to set the inner material from within my in-game editor at any time, during Runtime!
#In UE3 UDK
import the same .apb into UDK and you will see there are two materials listed and they can be set individually
#In UE4
There is only 1 material, you can add another but it does nothing
#Summary
- There is a loss of information and unrecoverable loss of functionality when you import the same .apb into UE4 vs UE3 UDK, the inner material is lost
#Thanks!
Thanks!
Rama
