Hi, facr73,
The RPublishing Pack provides two formats meshes. One is the High Resolution (Original high poly), the other is the LOD (Low Poly) format.
The high resolution format is designed for the still image rendering use; and then the LOD (Low poly) is for the animation in iClone purpose.
For example, the Dark Alice pack, \Cloth\Skirts\RPublishing\Dark Alice, the "DA_F_Skirt_L_01.ccCloth" is the LOD file, and come with the weight map, and allow you can have a nice cloth animation in iClone.
And the \Cloth\Skirts\RPublishing\Dark Alice\High Resolution, the "DA_F_Skirt_H_01.ccCloth", is the High Resolution mesh for still image rendering use, so it doesn't provide the weight map.
We provide a
video link for you, and you may understand it.
Thank you, and have a nice day.
Best Wishes
Cory
