These lovely garments were made using Blender 3D taking accurate measurements into the 3D world and modeling a cloth the same size and length to a female model. We used shape keys and drivers to create an animation with each frame a different size to show different body types when the garment is worn.
The figure in these renders and in the file is using a hold out to make it invisible so that an image of a person in the same pose could be dressed with the saree.
The exported versions are a single static pose. There is a blend file with the driven shape keys and one with the static pose.
*The key driven version of the saree uses several modifiers including mesh deforms and multiresolution modifiers that will not translate to other software. *
There is also a collection of 6 saree textures made by me that you can feel free to use if you don't have textures of your own in a zip file called Extra Textures here on CGTrader.
There is also a rigged version of the saree available in my store for those looking to do animation with this saree.
