crash when setting movement mode to left hand #5

Closed Tokusei closed 3 years ago

Tokusei commented 3 years ago

Hi, I am getting the following exception when changing bRightHandMovement to false in the default properties of VivePawnCharacter blueprint. Seems like it is trying to setup the controller movement moves and has a reference to a non-existent variable in GraspingHand_Left

Assertion failed: !Export.ClassIndex.IsNull() [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/CoreUObject/Private/UObject/SavePackage.cpp] [Line: 3789] Export SKEL_GraspingHand_Left_C /Game/VRExpansion/Vive/Testing/GraspingHand/GraspingHand_Left.Default__SKEL_GraspingHand_Left_C class is not mapped when saving /Game/VRExpansion/Vive/Testing/GraspingHand/GraspingHand_Left

Can you try fixing up redirects on the grasping hand folder? That is an asset ptr issue.

Tokusei commented 3 years ago

Hi, I have fixed redirectors in the folder, However the crash still occurs.

Can you open up the skeletal mesh for the left hand and the left hand itself and save and compile and save them?

If this fails you may have to re-create the skeleton, its the engine failing to find a directory path.

Hi, If I open and recompile these assets, The editor will start crashing, This is even if I dont change the boolean flag in the pawn class to use right handed movement. Looks like its trying to save SKEL_GraspingHand_Left which doesnt exist, The only skeleton asset in the folder is SKEL_UE4Mann_LeftHand I tried creating a copy of it and renaming, however it still seems to be crashing Is there a hard reference to this asset in the plugin code or something?

Tokusei commented 3 years ago

Hi, I found a fix, I renamed the skeleton to SKEL_GraspingHand_Left then duplicated it. I retargeted the original to the duplicate skeleton and it seems to be building. Renaming/Replacing References didnt seem to work. Not sure what causes the issue but hopefully it will be stable when packaging image

For therecord there is no hard reference no, seems like a bad import
