Chapter 1:4 – Value Control, takeaways:
– When you are controlling values and you see the gradient in a flat plane moving left and right, you’d think that’s the only thing that is happening, but actually values are causing a shift in the Z axis as well. The handy value graph is a great tool to visualize the height information.
– The operation Add and Subtract shifts the values up and down.
– The operation Divide and Multiple scale the values.
– There’s some talk about linear interpolation along the gradient that I don’t quite get. It seems to be something about the gradient just going from left to right.
– The Power operation introduces curvatures and bending.
– The color ramp node is great for remapping a gradient, but even better is the map range node.
– Remapping the values linearly? I don’t get that. But I think it has to do with how Spikey has been throwing a straight line in the Cartesian plane sometimes when showing some math.
– The efficiency of the node tree is something to keep in mind since it can bog down a scene with too heavy computation.
