Collisions not updated when moving UInstancedStaticMeshComponent

Hey !

It seems that the collisions are not updated when moving an object composed of UInstancedStaticMeshComponent.

When moving a static mesh component, the collisions are following the object (objects collisions and mouse hovering).

But when moving an instanced static mesh component, the collisions are remaining at the same place until a redrawing is forced.

Here is a video to show you the problem:

I can use AddActorWorldOffset or SetActorLocation to move the object, the behavior is the same.

This problem has been around for some time, i already opened an issue in 4.7 which was supposed to have been corrected in 4.8:

but it’s still happening in 4.10.1.

Thanks,

Cedric

Hi ,

It looks like UE-13673 is back open. It may have been re-opened as a regression or the fix did not make it into 4.9, though unfortunately I don’t have any additional information on why this is. I do not have a timeframe of when this will be addressed.

Any word on this?

At present our resources are dedicated elsewhere. Unfortunately, I do not have a timeframe of when this will be addressed.

Hi Has this issue been solved? Because I’m getting this same error in version 4.14.
Any idea of how to solve it?

Hi RDaneelOlivaw,

I believe what you are seeing must be a different issue. I just tested this in 4.14 and I couldn’t get your results. According to the JIRA this was fixed back in 4.13 and verified.

Could you create a new bug report and make sure to post full repro steps and/or a test project?
