You can use [pix_snap] after [curve3d] to convert the texture to a pix again.

Looks good, but now a bigger problem came up.

My aim is to correct the fish eye distortion for pix_movement and pix_multiblob analyses.
Which means first I have to make the curve3d correction and then use those pixels in pix_multiblob.
Is it possible?
