VOP Output Names

Show Full Input and Output Names on VOP Nodes

So we all know about Houdini’s dynamic duo nodes VEX and VOP. For those unfamiliar with programming, VEX nodes may be a bit intimidating. However, this is where VOP nodes come to the rescue. Think of VOPs as visual programming. If your coming at Houdini from a Cinema 4D angle, think Xpresso. Now I’m not saying working with VOPS is a walk in the park but it’s a nice entry into the world of VEX. Check out some of the great tutorials with extensive use of them over at Entagma if you want some practice. Here is a tip on how to show full input and output names on VOP nodes to help familiarize yourself with the common attributes in Houdini.

Input & Output Names

By default, Houdini shows the user the abbreviated input and output names of attributes such as ptnum, numpt, v, etc on the VOP nodes. When you’re starting out it may be hard to remember what they refer to.

 

Here is a quick solution that can help by showing you the full names on the nodes:

  • Open up the Houdini Preferences.
  • From the dropdown menu select Network Editor, Nodes, & Trees
  • Towards the bottom, in the Node Tiles section, turn on Show Full Input and Output Names on VOP Nodes.
  • Press Apply then Accept or just Apply.

Now, the newly created VOP nodes will show the full names of the variables. Once you learn them, you can switch back to the abbreviated form to reduce the clutter.
