How to use noise SOP

Beginners

Please tell me how to make cloth sway irregularly in the wind using Touch Designer’s grid SOP and noise SOP.

Hi @Muneyoshi_Risa,

welcome to the community.
The Noise SOP perhaps is not necessarily made to simulate wind movement but perhaps can instill the idea.
Theoretically you can just connect a Noise SOP to a Grid SOP.

What have you tried so far and where are you getting stuck?

Thank you for your reply. I want to express the appearance of curtains attached to a room window swaying irregularly in the wind. What I tried was to set rows (horizontal lines) to 40 and cols (vertical lines) to 40 in the grid SOP, connect it to group1 and set start 0/end 1439 to create a stationary part at the top of the curtain. I connected a noise SOP to group1, but the movement is larger than I expected, so I’m stuck.

Hi @Muneyoshi_Risa,

instead of the Noise SOP, have a look at the Spring SOP and perhaps this Tutorial here can give some pointers:

Thank you. That’s close to the movement of the fabric I want to express. I’ll use that as a hint and try making something.
