About cloth - I meant, for example, ability to change a color of texture parts; that would require textures with color-coded regions and matching blueprints, which might be cumbersome to create for a beginner. Therefore it would be great to have a collection of generic clothes but with dynamically colorable textures. They are using the same approach in Sims, I guess; and also Mixamo Fuse is using it:

scroll to Color Mask. This would provide infinite coloring abilities - you can have one shirt with multiple color zones and thus users of your plugin and basic clothes would not have to go to Photoshop and recolor a texture if they want just a different shirt; and also this could be good randomization option for spawning NPCs to make them look different although all are using the same set of base textures.
