Need method to easily toggle between BioMorphFace when settings menu updates

[henbagle]

We have several cut unique faces for NPCs that could be restored as an option in the settings menu - except the methods for updating an NPC's appearance don't work as well as the methods just updating a material.

As far as I can tell, the UpdatePawnAppearance method can be a little glitchy. the user will see the NPC pop in and out of existence when it occurs, and I've had instances of NPCs falling through the floor. Plus I don't know what would happen if the NPC was midway through a line of dialogue. Is there some way we can develop to instantly update the morph face without triggering this method?

Vegz to the rescue! Code snippet is below.

Class SFXSeqAct_SetMorphHead extends SequenceAction;

var(SFXSeqAct_SetMorphHead) Actor Target;
var(SFXSeqAct_SetMorphHead) BioMorphFace oMorphHead;

public static event function int GetObjClassVersion()
{
    return Super(SequenceObject).GetObjClassVersion() + 1;
}
public function Activated()
{
    local BioPawn Pawn;
    local SkeletalMesh oMesh;

    Pawn = BioPawn(Target);
    if (Pawn != None)
    {
        ApplyMesh(oMorphHead.m_oBaseHead, Pawn.m_oHeadMesh);
        Pawn.ApplyMaterialParameters(oMorphHead.m_oMaterialOverrides);
        Pawn.ForceUpdateComponents();
    }
}
private final function ApplyMesh(SkeletalMesh SkelMesh, SkeletalMeshComponent MeshCmpt)
{
    local int I;
    local Name nmActiveEffectsMaterial;

    if (SkelMesh != None && MeshCmpt != None)
    {
        nmActiveEffectsMaterial = MeshCmpt.GetEffectsMaterial();
        MeshCmpt.ClearEffectsMaterial();
        MeshCmpt.SetSkeletalMesh(SkelMesh);
        for (I = 0; I < SkelMesh.Materials.Length; I++)
        {
            MeshCmpt.SetMaterial(I, None);
            MeshCmpt.CreateAndSetMaterialInstanceConstant(I);
        }
        if (nmActiveEffectsMaterial != 'None')
        {
            MeshCmpt.SetEffectsMaterial(nmActiveEffectsMaterial);
        }
    }
}
