I added new clothes to the Metahuman character. However, when I add them to the Mutable plugin, they are incorrectly displayed out of place.
Solution: you need to convert the object to Skeletal Mesh. Then in Modeling mode, fix the pivot to “world orientation”, turn the model in the right direction and save. In “Bake Transform” mode, save the changes if the object was scaled. Then convert the object back to the skeletal mesh and distribute the weights.
