But you can zero out the transforms or simply right click them and “revert to default”, which will return the object back to where it was but now with the pivot matching it. The first is to click the “move centroid to origin” button, which will move your object to the world origin which lines it back up to your pivot, only now it’s in the wrong place.

There are a couple of quick ways to do this: When you drop down a transform node, the pivot point defaults to the world origin, but the object you want to transform is somewhere else in world space and you want the pivot to match. It helps keep things quick and clean to read in the Geometry Spreadsheet and stops them from unexpectedly affecting any nodes further down the network. Remember to delete attributes and groups when you no longer need to use them. And if a node is not behaving how you want, it’s good to check if the attributes you're feeding into it are correct, in case it’s a problem caused further up the network. It can quickly help you locate which node is affecting them in unwanted/unexpected ways. Make sure to use the Geometry Spreadsheet to track your attributes and help debug issues in your scene. There’s a lot of useful information in here, but it should show you any attributes that exist on that node, and if you click on an attribute, it will display that with a marker in the viewport so you can check visually if things are okay, or if you’re vector is pointing down for example! If you create a new attribute, you can quickly visualize it in the viewport by hitting the “i” icon which appears when you hover over the node where you’re creating it.

This can often happen with geometry that’s been negatively scaled in one axis. Sometimes geometry appears dark/grayish blue in the viewport, which looks like the normals are flipped, but sticking down a normal node and ticking “Reverse Normals” doesn’t solve the issue? This can be caused by the vertex numbers going in “wrong” (anticlockwise) direction and can be quickly fixed with a “Reverse” node which reverses the vertex order, so they go clockwise. When “Reverse Normals” doesn’t solve the issue Changing the viewport to manual means the viewport will only display changes when you actively choose, meaning you can make as many changes as you need without Houdini attempting to recalculate on every button press.Ġ3. By default, the viewport will update changes you make automatically but this can be tedious when you need to change multiple settings on (for example) a detailed simulation.

When working with heavy scenes the viewport can become slow. Change viewport to manual for heavy scenes If you can get away with doing something through code rather simulating, it will often give you a faster, more efficient result which will likely be easier to control and only when you can't get any closer the desired final result should you the resort to simulating.Ġ2. The initial appeal of Houdini is all the impressive simulating it has the potential to do however most FX artists would agree that you want to build as much of the scene without simulation first.
