When a provided retargeted character example is used, i.e. CBP_SandboxCharacter_UE4_Mannequin - which has been updated with a custom character blueprint (another child, probably the main use case for existing projects) the ABP AnimInstance fails to link up with the ‘child - child’ CharacterMovement component.
The same, when a custom character is directly linked as child of CBP_SandboxCharacter
This suggest that GASP is not linking with custom project character - CharacterMovement components. The alternative to move the entire code of a custom character into a RetargetedCharacter example is likely for most use cases not feasible due to crash when attempting to delete/replace custom character, or due to extensive code base recreations with a new base character and all related features.
Error
Blueprint Runtime Error: “Accessed None trying to read property CharacterMovement”.
