Greetings all!

I need to align an object to a point (without using Copy SOPs).

I found a short tutorial on this that uses a VOP SOP with "Align" and "Extract XForm" nodes. This works exactly as I'd like it to, but I need to rebuild it as it was created in Houdini NC, and is also a few years old so it appears some of the nodes have been deprecated.

I did my rebuild approximating the original file with non-deprecated nodes, however, I'm not getting the normal-to-rotation alignment I need and I'm at a loss for where to look to resolve this. Attached are screenshots, one derived from original file (Non-commercial), the other is my re-build (Indie). The results in the Geometry Spreadsheet tell the story.

Respective .hipnc and .hiplc files are also attached.

Preemptive thank to any responders!

I can't really tell what you're doing with an attribute 'rot', but there is a problem with the attributevop version.
Using 'add attribute' with a point-varying value does not do what you expect. That node only creates the attribute, it doesn't set the value to anything, aside from the default value , which is the same for all points. That's why the first point's value is the same on all of the points.

Use a 'bind' node to set an attribute value for the current point. There's very little reason to use an add attribute node unless the name/type of attribute needs to be determined procedurally.

I appreciate the response! Replacing the Add Attribute VOP with a Bind Export seems to have done the trick!

Regarding the 'rot' attribute, I was using this to drive rotation values which I'm referencing in a few Transform SOPs using expressions.

As I'd mentioned, I'd borrowed that VOP setup from someone else's old file. It's a bit of moot point, but I do wonder why SideFX changed the functionality of the 'Add Attribute' VOP.

In any event, thanks again!
