I would like to enable modders to copy morphs from one SkeletalMesh to another.
I wrote simple Python script to do that.
#Takes the last element of all selected stuff in the Content Browser
#Copies all morph targets from selection - excluding the last element - to the last element
#array = from1,from2,from3, ... , lastElementThatTakesAll]
import unreal as ue
from unreal import SkeletalMesh, MorphTarget
# create unreal class instances
editor_util = ue.EditorUtilityLibrary()
#material_util=unreal.Material()
# get the selected assets
selected_assets = editor_util.get_selected_assets()
lastmesh=selected_assets[len(selected_assets)-1]
morphtargets=lastmesh.morph_targets
print("lastmesh morphs: ")
print(lastmesh.morph_targets)
for morphlist in selected_assets:
if(morphlist==lastmesh):break
print("List: ")
print( morphlist)
for morph in morphlist.morph_targets:
print("Morph: " )
print(morph)
morphtargets.append( morph)
lastmesh.morph_targets=morphtargets
It does work, I can see the sliders on the Receiver mesh in Persona…
The issue is it only works with identical meshes/duplicated ones… Not very useful.
If I import it with different settings the morph target sliders don’t do anything, even though the mesh is “nearly identical”.
I wrote BP node to do the same thing, but the results are the same… sliders are present, but aren’t doing anything.
bool UVictoryBPFunctionLibrary::AddMorphTargetToSkelMeshFromSkelMesh(USkeletalMesh* Receiver, USkeletalMesh* Sender) {
auto senderMorphs = Sender->MorphTargets;
for(auto morph : senderMorphs)
{
Receiver->MorphTargets.Add(morph);
}
return true;
}
I tried the RegisterMorphTarget function as well, but this one just crashed the editor.
Tried calling both in the construction script/beginplay as well.
bool UVictoryBPFunctionLibrary::AddMorphTargetToSkelMeshFromSkelMesh(USkeletalMesh* Receiver, USkeletalMesh* Sender) {
auto senderMorphs = Sender->MorphTargets;
for (auto morph : senderMorphs)
{
bool valid=Receiver->RegisterMorphTarget(morph,false);
//GEngine->AddOnScreenDebugMessage(-1,15.0f,FColor::Red,"morph name: "+morph->GetName());
}
return true;
}
EDIT:
This line causes the crash:
Receiver->InitMorphTargets();
