So I’m using this tutorial. The only difference is that I am using Houdini
My steps after I exported Head and Body mesh
1.Scale up the head and body together a little bit (scaling on z axis at 1.02 times). Sculpt them a little bit.
At this stage, the head and body’s open edge still matches
2.Import body back to UE.
No problem
3.Import head mesh to UE by defininf source mesh path and then hit reimport base mesh button
4.Now head and body mesh cannot match together
This is the screenshot of the metahuman blueprint I modified. Metahuman causes a significant gap between neck and shoulder
5.Debug
Export the modified body and head mesh again and read them in Houdini
I don’t know why the hell does Metahuman’s head skeletal architech tend to wreck the the vertex position (and why the body does not get wrecked); the whole thing looks like setting problems to not letting changes happen to metahuman stock resource. This problem occurs after 5.3
Any clue what might force the head mesh to change the shape?
