I have have a skeletal mesh with 5 LODs. I added chaos clothing data to LOD 0, painted it and then “Create Clothing LOD from Section” for the other LODs. I decided to remove the LODs of 3 and 4 which sets Clothing to None in the “LOD Sections” by the Material Slot. This stops the simulation on those LODs, but I can find where to delete them completely from the clothing data.
Here I selected the mesh on LOD 3 and Remove Clothing Data
This removed it from the LOD 3 Sections by the Material Slot
But the LOD still exists in the Clothing Data
