UE 5.5.1 NPC Collision Settings

[Dalaware]

Hello

UE 5.5.1 NPC Collision settings not being saved
I have compiled and saved and save all
closed Unreal reopen to find the settings are not saved they have reverted to their original settings

is this a bug?

Hey there @Dalaware! Is your NPC of the Character class? How shortly after save completion did you close? Is this reproducible?

[Dalaware]

Yes it is a character class, Unreal did not complain about saving as I exited the program.

[SupportiveEntity]

Do any character details save upon exit? Are you using custom collision channels?

[Dalaware]

This is what I have saved in mesh collision settings changed Camera and Visibility
also I have blueprint for damage
Image 1 is my blue print damage NPC
image 2 what I have saved
image 3 the state of the collision detail when restarting Unreal 5.5.1

Same Issue here.
Collision on the Mesh component of my NPC’s will not save.

Hey there @Ironthumbs! Welcome to the community! It’s interesting, I can’t seem to replicate the issue itself, as changes to any collisions always end up being retained. There must be some form of environmental variable causing this loss of data. The issue is hard to diagnose since it doesn’t seem the other character data is missing.

For reference, any runtime changes won’t remain when play mode is over, in reference to the BP shown.

Hi
I have remade the program in UE5.4.4
works perfectly no issues at all NPC collision data is saved correctly after restating UE5.4.4
it must be a bug somewhere I can not be the only one with this problem!

Thanks for the update! Since that worked, there’s probably some cached data issue in the original project. I’d recommend backing it up, then deleting the Saved and Intermediate folders from the project and let them regenerate.

Hi
Did as you suggested deleting the Saved and Intermediate folders, still did not save the collision data on restart for the mesh, although it is saving the collision data for the capsule.

[SupportiveEntity]

Interesting! I would recommend reporting this as a bug if you can replicate it in other projects. Although since the mesh itself retaining it’s parent’s collision information, this may not be a problem for your use case.
