Tech Note: Property access on array types in anim nodes fails to compile

Dec 8, 2021.Knowledge

Description : Array types are currently not supported with property access directly on animation nodes

Potential Impact: Limited: Anim BPs that attempt to use property access to set array types will fail to compile with a check failure in FPropertyAccessSystem:PerformCopy()

Solution: The issue will be resolved in UE5. The workaround to use property access for these variables is to use the Property Access node to get the values.
