How can i make the cloth fold and the wrinkles on it. I tried this.

enter image description here

But i want to achieve this

enter image description here

I do not want to animate this cloth. Just to similar how can i achieve the fold and wrinkles and the way look natural. Any suggestion or help. Thanks

In order to create such a 'folded' structure using the physics cloth simulation, there are two things you need : sufficient detail to your cloth mesh and sufficient 'spare' cloth to allow it to arrange itself into folds.

Without sufficient detail in your cloth you will old get coarse folds - there just isn't the geometry to create anything else. However, bear in mind that the more detail you add to your cloth mesh, the longer it will take to simulate. In my case I used the following heavily subdivided mesh as a base :

undistorted cloth mesh showing vertices

In order to create the 'spare' cloth you need to create it 'spread out' and then manipulate it to draw it together. This will naturally create 'folds' as there will no longer be sufficient space for the cloth - similar to when a real curtain is bunched togther. In order to achieve this you can 'pin' the sections of the cloth you want to manipulate and then use Shape Keys to manipulate them, leaving the rest of the cloth to behave as per the simulation.

Start by selecting all the 'top-edge' vertices. Create a new Vertex Group and 'Assign' the selected vertices to that group. Name the group 'Pin'.

In the cloth simulation, set 'Pin' as the group to use for Pinning.

Similarly, select the vertices at the bottom of the cloth that you want to manipulate, create another group named 'Hook' and 'Assign' the vertices to that group. Also assign them to the 'Pin' group (very important!!). The 'Hook' group can be used to conveniently locate your vertices, while the 'Pin' group tells Blender which vertices are being controlled independently of the simulation.

Next, add some shape keys - the first one is the 'Basis' key (the one all the others are based on). Add another shape key (Key 1) - this will affect the top edge. While Key 1 is selected, select the top row of vertices and scale them down to a point (S0Return). Now, adjusting the strength of Key 1 will draw the top vertices together.

It's also helpful to sepearately select the 'Hook' vertices (while still having Key 1 enabled) and also scale those to a point. In this way, as we use Key 1 to draw the curtain together the hook points will stay below the same point in the curtain.

Add another shape key (Key 2). Whilst it's selected, move the 'Hook' vertices to their desired location for raising the bottom edges (bring them forward slightly and 'up').

Now you can simply run the simulation while manipulating the Shape Key strengths. This should have an effect similar to the following :

Once you're happy with the motion, you can enable 'Self Collision' of the cloth simulation to ensure the folds behave consistently and don't intersect. However, note that this will considerably increase the time required to run the simulation.

  • $\begingroup$ woww really look awesome i would have to try. But how it work for low config PC. Thanks $\endgroup$ – atek Oct 8 at 9:18
  • $\begingroup$ @atek I do all my work on a laptop with 8Gb memory and the cloth sim isn’t too slow - although much slower if self collision enabled - so it depends on how your system compares. I think the memory will probably be the limiting factor. $\endgroup$ – Rich Sedman Oct 8 at 9:33
  • $\begingroup$ Thanks for the detail answer and afford take to give the answer. I have created the fold different way with a cloth addon. This is my final render imgur.com/a/bEU1IV3 $\endgroup$ – atek Oct 20 at 2:47

Such an outcome can be achieved by combining cloth simulation and sculpting.

  1. Cloth simulation will give you realistic overall shape. Blender Guru tutorial covering the basics
  2. Sculpting allows you to manually add more wrinkles where you need them.

Hope this helps.

  • $\begingroup$ In this video its drop down. I want to fold the cloth. it should fall down then some part to be pull up. $\endgroup$ – atek Oct 2 at 16:01
