Hi there,

A Grid SOP.

A source of noise (Noise TOP, TOP to CHOP, a shuffle and a Math CHOP to put everything from 0,1 to -1,1)

I take coordinates with the SOP to CHOP from the Grid SOP. and I combine that with my noise using a Math CHOP that acts a bit as a dry wet, multiplying the noise influence before going to SOP rendering.

The process is easy to understand for me… until the next part.

The distortion occurs well etc BUT when I stop the influence of noise by putting my Math CHOP to zero, I don’t have the same rendering as the initial grid.

I know it is a question of vertices order… but what did I do wrong there?

Would someone help me to go out of my error here ?

I’m stuck.
