Hello, because in the materials with which the program comes there is no option to choose a model in 3D child version, I share the one I made for those who want to have it and can use it quickly.
The downloaded materials will be saved in the CLIP STUDIO PAINT Material> Download palette.The downloaded materials are also displayed in the Download folder of the "Manage Materials" screen of CLIP STUDIO. To use 3D pose materials, drag and drop them on the canvas.
