how to paste different color in Sop

Hi I’m beginner for TD, recently I want to simulate a Flip-Dot Wall using the picture in Touchdesigner.
so I have two problem that it’s diffucult for me to solve it.
Firstly, how can I make paste two different color into the two side of the circle Sop (cuz,I use circle sop instance with grip sop.)
as below the pic is what I want

Although I try to use texture sop to solve it, it did’t work.

Sceondly, how to simulate the physical sound activated when flipped , that is ,when the circle sop have rotated will be activated some sound per circle, how can I do this??

hello,

problem is that you can’t merge 2 SOPs with different materials, otherwise it would have been simple to make 2 sides from 2 SOPs.

Using a 3D modelling software you would need to unwrap the UVs and color each faces with a texture. So probably a bit messy here, but to mimic this the idea would be to use a 2 colors texture and project it on a cube SOP and adapt the texture size using a texture SOP

Now if somebody else comes with a better idea… :slight_smile:

See example attached

Thank you so much!! I think I can further understand it
