edit - I found a solution - I had to generate a fake N from orient inside Houdini and export both orient and N, then I used this normal as Look at the direction in "orient mesh to vector" module + orient as quaternion override + N as reference axis vector + 1 override incoming orientation. This feels like an overly complex answer to a simple rotation question.

I found a simple solution:
In "Orient Mesh to Vector"
1. Apply @up to 'Look at Direction'
2. Apply @N to 'Side Axis Direction'

hi
I am struggling with this.
Could you explain this a bit further?
thanks!

Hello!

I am struggling to get my rbd sim to have the correct orientation in Unreal 5.1.1

The orientation seems wrong. I am using the niagara ROP and plugin to get the point data to Unreal.
It seems one axis is wrong or something because they almost behave like they should but have a weird wobble.

I recreated the issue inside Houdini with a copy to points sop where it has the same issue.

Attached the hiplc file.

Any tip would be awesome!

Thanks in advance!

I am trying to achieve something like this in Karma XPU.

Is there a way to do colored volumes with materialx and karma xpu yet?
