How to create seam on fabric in 3D Max software. After modeling the curtain, to create a seam on it, it is enough to select one of the edges as a loop.
It is enough to extrude that edge inwards or we can first chamfer and select the middle line and now we will extrude inwards.
We increase the strength of the osmosis modifier to see the seam better.
In the example of the pillow, first we model the pillow, then we extrude the middle line of the pillow to the inside.
Now we can see the seam on the fabric of this pillow well from all angles.
