Issue with Vellum Constraints not generating where intended

Recommended Posts

Greetings all,

I'm working on a shot where I have a spinning falling cloth. In order to control it I have the center of the Vellum cloth attach to an animated object. It was working fine for a while, but somewhere when I iterated my .hip file up, the constraints started to be generated off center. I tried to match the settings from the previous correct one and even copied the properly functioning nodes over, but it was still misbehaving. I attached a photo of what it should look like vs what's going wrong.

Even stranger is that in the attached .hips, there's a rogue switch node that if I delete it, the constraints won't form at all. It happens in both the correct and wrong versions. The switch node isn't even connected to anything in the stream of data as far as I can discern. The .hips are reduced from the larger shot I'm working on and the switch is a leftover from removing the collision geo after a certain point.

For the moment I'm going to back step to the working .hip, but I was wondering if I'm missing a setting or this is just a bug. I have a hunch this might be an issue with using Vellum in a SOP context, but I'm not certain.

Using Houdini Apprentice 17.0.352 on Windows 10.

Thanks!
