You may not know this but there are many operators in Houdini that are just digital assets created from existing operators. Some that come to mind are the Mountain SOP and the Assemble SOP. There are plenty more. Ok, so? Well, a nice way to learn how some of these assets are created or learn more about working with Houdini is to dive right into a network and poke around. The nice thing about it is when you extract Houdini digital asset contents, you are not messing with the original HDA so you can break things to your heart’s content. […]
If you are looking to match transformations similar to Cinema 4D’s Transfer tool, Houdini also has this ability tucked away in the parameters pane. Not sure when this was introduced but it quickly allows you to match one object’s transformations to another one. Match Transformations I completely missed this or just never noticed them. Right next to the transform parameters on your geometry node, you will see on the right side some icons. Just click on one of them, select you target geometry and you are good to go.
Sometimes jumping back and forth between nodes to change certain parameters gets tiring. If you are a Cinema 4D user, you might be familiar with how to add HUD sliders or various HUD elements to the C4D viewport. It’s a really nice way to create a UI for yourself or other users. Houdini offers the same functionality. Add HUD Sliders in Houdini Adding a hud slider to the Houdini viewport is just a matter of dragging the parameter name to the viewport. If you right click on the slider, you have several options such as displaying the HUD element, making […]
If you have a network setup you would like to save and quickly recreate, Houdini has a nifty trick for you that lets you save network setups to the shelf. No need to manually recreate or copy and paste from one scene to the other. Save Network Setups to The Shelf This is like creating a preset. Just select all the nodes in your network or select an object level node and drag it to your self. If you are selecting multiple nodes in a network, Houdini will ask you a few questions about creating the shelf tool such your […]
If you want to disconnect nodes from a network in Houdini, you can right click on a wire and use the options in the context menu. This method is the slow way. You can also shake the node off. While shaking is handy and kind of fun to do, there is a faster way to quickly disconnect network wires. Quickly Disconnect Network Wires All you have to do to cut off a bunch of nodes from the wires is hold down the Y character key and slash away. Try it. It’s very satisfying.
The tooltips when you’re starting out are a lovely thing in Houdini. You know, the help snippets that pop up when you hover over a parameter. However, you may have a good reason to turn them off. Maybe they are just getting in the way. Rejoice! You can disable tooltips in Houdini. I’m sure not surprised. Disable Tooltips in Houdini Your first instinct may be to head to the Houdini Preferences window but you won’t find the setting there. You have to go the menu no one ever uses. Yes, the Help menu. Click on Help and uncheck Tooltip Help.
Sometimes you just want a clean interface with the main parameters you intend to manipulate. Take for instance a Point VOP. It has all that extra stuff you are not going to touch. Maybe you are creating tools for artists to use. In this case, you just want to expose the main parameters for your tool. Well, let’s make parameters invisible. Make Parameters Invisible In order to hide parameters, all you have to do is open up the Parameter Interface window, select all the parameters you want to hide from the main interface and check the Invisible option on the […]
If you have all your nodes scattered around your network view, you can hit the hotkey l and Houdini will layout your nodes as it sees fit. However, you can also choose the direction of laying out the nodes yourself. Laying Out Nodes in Houdini Hold down the letter a on your keyboard and then swipe from the node left, right, up or down. Nice!
You see all those cool kids with their Houdini color pane headers? Do you want your Houdini interface to look like that? Sure you do. Color pane headers are just one click away. Color Pane Headers Open the Houdini preferences and check the Color Pane Headers with Network Contexts. Done.
We are going to take it easy on this #QuickTip with some Houdini playbar basics. We last tackled a lengthy Python series so you may still be digesting those. It was also a tough week in my neck of the woods. We had Irma, a category 4 hurricane pay us a visit. Luckily, I just had a minor leak in one of the rooms from the rain and power was only out for a day. I was lucky. In a previous storm a few years back, I was without power for a month. Key Selection The first thing you need […]
We’re going to wrap up our Python and Houdini start up scripts series by addressing one last thing in our script. While our script worked upon launching Houdini, it did not appear to run when creating or opening an existing .hip file. We’ll address this issue in a couple of ways and introduce a few new concepts along the way. This is a bit dense so grab your Yoo-Hoo. If you need to catch up, here are the posts: Python and Houdini Start Up Scripts – Part 1 Python and Houdini Start Up Scripts – Part 2 Python and Houdini […]
Previously on the Six Million Dollar Man we talked about Python and Houdini start up scripts and how to go about creating them. If you need to catch up, have a look at part 1 for details. In this second part we are going to focus on refactoring the code and working a bit with Python functions. If you need to catch up, here are the posts: Python and Houdini Start Up Scripts – Part 1 Python and Houdini Start Up Scripts – Part 2 Python and Houdini Start Up Scripts – Part 3 Refactoring Once you get your scripts […]
