I recently got a chance finally to see the new $100 note here in the States. I thought it would be a fun test to try an emulate the 3D security ribbon with nodes.

We could also do 5 or so images and emulate a lenticular print.

By using Math > Scalar > Multiply you are destroying vector that you just made with Make Vector..
You can get rid of Make Vector, or use Math > Vector > Multiply (or Math > Vector > Scale, it's like multiply the all XYZ by the same value).

OK cool, that's what I originally wanted, but having not spent a great deal of time in nodes I'm still getting a handle on it.

However I also like the distortion that happens with my happy accident. For this application, I think it actually helps the effect.

Thanks for the tip!

Since you're making a vector using just the incidence input into X, then your YZ are 0... sending a vector into a scalar input (as u have with the multiply) gets only the X (so YZ still 0)... as such, using a vec mult there would make no difference... as in fact, would taking out the make vec, its not needed inbetween the incidence and multiply. U'll also find that if u wanna play with the amount of angle, that instead of having 2 gradients, its easier to just have 1, and simply invert its output to connect into the second opacity.

No.
Conversion from Scalar to Color copies it to the all components RGB.
Conversion from Scalar to Vector copies it to the all components XYZ.

Math > Scalar > Multiply and Math > Vector > Multiply all have 1.0 and 1,1,1 as 2nd input.

Thanks to both of you for weighing in with your expertise. I knew my setup wasn't optimized by any means, but it never will get optimized if I don't start somewhere.
