The Cloth Paint Tools have many options and properties that you can use to make very specific clothing simulations. Below you'll find the details about the menu options you can use when creating your clothing assets and details about the Cloth Paint panel that you will use when selecting different painting tools to paint cloth values for your render mesh.
In this section, you'll find the details about the properties and settings you can use when creating and applying your clothing assets to your render mesh.
Section Selection
The Section Selection menu is available by right-clicking a selected section. It enables you to select the different material elements of your render mesh to create and apply a clothing asset. In this menu, you can identify the LOD and a material section of your mesh that you've selected, create a cloth asset for your render mesh and its LODs, apply the clothing asset to the selected section, and remove it later if needed.
