No collision When changing StaticMesh ingame?

[Voleuro]

Hello Community,
I'm currently trying to change some Meshes in game. And that's working fine for now. The only problem is, these objects have no collision.
I added a convex collision to the StaticMeshs Objects in the Browser. Then I change the mesh to one of these, they don't have collision.

Here's the script I'm using:

class ObjectOverTime extends Actor
    placeable;

var() instanced StaticMeshComponent MeshComp;
var() StaticMesh Dimension1;
var() StaticMesh Dimension2;
var TimeField TF;

function UpdateDimension() {
    local float dist;
    ForEach DynamicActors(class'TimeField',TF) { //my One
        dist = VSize(TF.Location - Location);
        if(dist <= 512) {
            MeshComp.SetStaticMesh(Dimension2);
        }
        else {
            MeshComp.SetStaticMesh(Dimension1);
        }
    }
}

defaultproperties
{
    Begin Object class=StaticMeshComponent Name=Mesh1
		CastShadow=true
		StaticMesh=StaticMesh'RoboPlaneten.Sofa' //Placeholder
		bAllowAmbientOcclusion=true
		CollideActors=True
	End Object
	MeshComp=Mesh1
	Components.Add(Mesh1)
}

Can anybody help?

Thanks,

I don't see any collision settings for the actor itself.

DefaultProperties
{
    bCollideActors = true
    bBlockActors = true // if you also need blocking
}
