Missing Motion Blur with RBD Disconnected Faces


Recommended Posts

Hello! This is my first post here, I am a Houdini beginner and I'm looking for some help with the project I'm working on.

I am breaking a glass panel, and there's an issue with the deformation motion blur that I want to have on the final render.

When I use the RBD Disconnected Faces to hide the inside faces on the glass before it is broken, the motion blur just randomly goes away on some frames and on others it's present. I've learnt that this issue might be due to the inconsistency of the topology, however I've looked through the timeline with the Integer Frames off and the interpolation looks smooth. Point velocities look fine too.

I know that there's an option to just swap the geometry at the moment of impact, but this won't work in my particular case.

Here's the hip file of the smaller version of the project, the motion blur doesn't work on frame 5 for example.

What am I doing wrong here?

Thanks!
