Does Substance Designer have a channel AND operator?

Hello everyone. I'm having some issues with colorID maps. These were pretty straight forward in painter but substance designer is a bit of a challenge. I use to mask things by channel and it worked fine. however the biggest problem I have now is working with an object that had more than 3 materials. I would like to mask pink RGB(1,0,1) but there is no AND operator. All things with red or blue appear.



The youtube tutorials only use separate texture alltogether so I decided to Google the problem. I found this forum in which a user makes a graph that only outputs true if certain colors are above a per channel threshold. The problem is he adds them but I'm looking to AND them.

I decided I would at the very least play around with substance logic but it turns out we need a function graph. The youtube videos from Algorithmic tell you how to play with it, but they never mention how to open it in the first place. See for yourselves.

There is a node in the library called Color to Mask, I think it does what you want, which is pick any color from a color map and creating a black and white mask from it.

I'm not seeing that node unfortunately. I'm on version 5. I eventually resolved this problem by placing in 2 "Replace color" nodes. The first one turns the red to black and the second one turns pink to red and I created the mask like that. I'm only working with 5 materials now but it's still going to feel weird working with several materials.

The node should be in the Filters > Adjustments section.
