Changing Scale of collisionComponent of InterpActor does not work

[dprat0821]

hi,
I made a custom interpActor generated and ejected when my pawn shots (like a fireball or bullet). It collides with other pawns and makes damage. If there is no scale change for that interpActor, everything goes well.

Now my problem is that my fireball should expand its size per frame with a factor. I found that I can only resize its drawing scale(representation), but the collision size stays.
I've tried following functions in Tick:

MyInterpActor.StaticMeshComponent.SetScale3D(OrigScale+Factor*DeltaTime);
or MyInterpActor.CollisionComponent.SetScale3D(OrigScale+Factor*DeltaTime);
or MyInterpActor.SetCollisionSize((OrigScale+Factor*DeltaTime).X,(OrigScale+Factor*DeltaTime).Z);
or MyInterpActor.SetDrawScale(OrigScale+Factor*DeltaTime);

I also tried to redeclaire MyInterpActor.SetCollision(true) after above steps.
In log, I can see the scale of its staticMeshComponent/CollisionComponent is changed, but with command "nxvis collision" or with the real collision test, we can see the collision size stays.

OK, solved.
I found that the collision size is in fact changed and works well. The only problem is that the command "nxvis collision" shows incorrectly(stay unchanged) after collision re-scaled.
IT'S A BUG!

nxvis shows the PhysX body instance, which is separate from unreal physics. You may find that when your interpactor collides with rigid bodies they will only be affected by the unchanged nxvis collision.
