Houdini Digital Assets
Youtube – Introduction to Houdini – Chapter 4- making digital assets
By: Rohan Dalvi
Making Digital Assets in Houdini seems to be a core part of creating a procedural model generator, so this tutorial gets into the very basics of setting one of these up.
The practice used here is that you create a Null object off to the side where you “Edit the Paramter Inteferface” under the settings of the node (the gear icon). You select the type of values you want to vary (floats, ints, ramps, vectors, colors, etc.) and add those to this Null object. Specifiying a range here can be helpful to inform the user of useful values. You then “Copy Parameters” from this Null control node, and “Paste Relative Expression” to the nodes/variables that they make sense. This way, when the Null control node has its values changed, they will directly correlate with changing the designated value within your network of nodes.
