posUvMatte_Bb_v02

Extracts shapes from 3D passes and moves them with your objects, tracking the UV pass.

(built upon the 3DMattes Gizmo by Pau Rocher : [email protected])

Feed it with a position and a UV pass through the 'in' input, and select the right channel for them.

Use the 'alt pos' input to create you shape selection on a second position pass.

Use the 'mask_uv' input to specify an object to work on (or it will use the first matching uv ccords from left corner)

Use 'side by side' mode to pick a UV value AND see the resulting mask at the same time.

UV mode :

use UV threshold to be sur you always get a matching selection (check show selection to check the range)

use the Offset U and V values to animate to animate the UV position (can be useful if part of your object gets occulted) or to select the right UV tile.

Use the 3D OFFSET to offset the resulting 3D position

Have fun !
