When I used the 'Get Instance From Patterns',those points' orient is not correct.I'm floowing the tutorial ‘Titan Tools’(https://www.sidefx.com/tutorials/project-titan-building-tool/ [www.sidefx.com] the 3rd section), but it's not working.(labs package 19.5.534)

Same here...

It's the same in 19.5.559

Did you figure out a solution for this?

In case anyone stumbles onto this thread, I had this issue also. What fixed it was adding a clean node with remove attributes after the object merge node (or what ever node is bringing in the mesh box object from unreal into Houdini.) Unreal is passing some data from the box into Houdini that does some thing odd to the orients of the boxes, regardless if you set them up in the correct angles / pivots with the building utility node.

I have the same problem and have been stuck for days. If I use the clean node just after the input node it just creates a different wrong orientation. Has anyone found a solution?
