Trims and Accessories.
You can always add your own trim to the program. Using photoshop it is easy to add laces patches, metal detail, lace trim and ribbons and import to the 3D software. A trim can used as seam and easily added on cut lines or edges of a garment.
All Over Prints.
All over print and placement print can also be added to all fabrics. So, you can mix different fabrics and different prints all in one garment. You can see the surface structure of the fabric through the print layer, so it gives a realistic look.
Stitching.
All stitches are visible on the 3D garments, so you can make changes all the way down to the actual stitch. Even the shadow of the seam is changeable depending on if it is an open seam or folded to one side. All this help making the 3D simulation as the real sample.
