Adding Random Fingerprints to Objects Using a Material.

[justpeeksmh]

Hello everyone,

I'm using a script called BrickIt to apply Arnold surface materials to all of my LEGO bricks. When applying these materials to the bricks it adds fingerprints using a roughness map and an aiTriplanar node. This works perfectly fine on stationary bricks, however, when I animated these bricks the fingerprints do not rotate with the object because the Triplanar's coord space is set to "World" . When changing the coord space to "Object" the fingerprints do move with the pieces. However, the fingerprints are no longer randomized per object. How would I edit this material so that the fingerprints adhere to the objects transformations and rotations but are still randomized per object?
