Hello, I'm working on a small project to have a bullet fracture a glass bottle in slow motion. I have come across a few problems while doing so and could use some help.. 1) The time warp is causing some strange scaling issue on the bullet. It continuously scales up and down. 2) During the render with the glass, you can visibly see all the fractures. Only way I can think of countering this is using a switch to switch between the solid and fractured bottle. But this wouldn't be the best option because, the effect being in slow motion, the transition will be obvious. Thanks for the help! bottle_fracture_v09.hipnc

"spherical linear interpolation" when blending primitive trans
Netvudu posted a topic in General Houdini Questions
Hi there. The journal reads Houdini 14.0.215: The Blend Shapes SOP and Time Blend SOPs now have an option to use spherical linear interpolation when blending primitive transforms. Thanks to this change, some time warps with packed primitives that were badly deforming the copies now work seemingly well. Can anybody explain what´s this and what´s going un under the hood. Wikipedia hints this is related to quaternion rotations but I could certainly take a specific explanation to what´s going on there.
