Creating the shading lines, part 1

“

- [Instructor] Although our visualization piece will most likely have shadows built into it by virtue of the lighting that we add, we're going to add a bit of an ambient occlusion effect to the material, just to help emphasize the fact that well, this is a stylized material, which is why we will borrow from some traditional out styles and create the occlusion effect using a hatch pattern. Coming to the substance graph, we will press the space bar and search for a add a striped node and then position it inside the shading frame. As we will want a fine hatch, well that's inside the instance parameters roll out. Set the stripes to value of 48. The width we will set at 0.7. And to get our angled hatch look, we will want to set the shift amount to about 20 or so. For a little extra control that we can expose to the user, let's with the stripes node selected press the space bar and search for and add an invert gray scale node. Then set it to false for now. This if we expose the true false option will just allow the user to quickly invert the size of the shading without having to expose each of the stripes nodes controls. If we would rather have complete control over the size of the shading, we can simply not add the invert node and instead expose the stripe nodes controls. I'm going to opt to leave it in place for now though. So with the invert node still selected, we can add a transformation to the node via the search feature. Now in this particular instance, we want to click the divide by two two button to change the scale of our shading. We could of course use a number of nodes to control the scale. Or as is already been said, simply expose parameters on the stripe node itself. So feel free to use the one that works for you. Now this approach just allows us to expose a fast and easy way for the user to either increase or decrease the shading line size. We could also make the lines thinner and add a copy that has an inverted angle amount to create a crosshatched effect too. So although we've made a good start here, there are still a few nodes to add in order to finish off this particular shading effect. And so let's jump into our next exercise in order to do that.
