Hi Dr. Sassi,Thank you so much for your reply and the links — I truly appreciate it!I’m actually aiming for something different than Squash & Stretch. What I’m trying to build is a smear effect — similar to the old CA Motion Stretch Deformer or Blender’s Smear plugin — where the object stretches dynamically based on its motion direction over time even the object animated with PSR keyframes or PLA or even aniamted in linear path or curved path the main goal is once i have an animation object i could have the smear look.

When i try it first time i think of:Analyze previous (and maybe next) point positions using memory,Stretch the object’s points automatic in the direction of movement, Optionally control the smear area using Vertex Maps or Fields,It’s more about motion-based directional stretching than uniform deformationIf this kind of effect is possible in either Xpresso or Scene Nodes, I’d be super grateful for any help — even just a rough outline or steps to guide me in the right direction.Thanks again!

Heey It's my first time here,
I’m trying to recreate a smear effect in Cinema 4D, similar to Blender’s Smear plugin or the old CA Motion Stretch Deformer. I’ve been experimenting with both Xpresso and Scene Nodes to build a reusable setup — one that works with PSR or PLA animation, affects points directly, and can be combined with other deformers like Jiggle, without needing to bake to Alembic.

The goal is to just replace the object, tweak some User Data, hit a button — and get clean, stylized motion stretch.

I’m sure this effect can absolutely be done and made powerful and production-ready. But I simply don’t have enough experience yet with Xpresso or Scene Nodes to build it properly.
And if I’m not being too ambitious — I’d love to also include a way to limit the smear effect using a Vertex Map or Fields, just like the old CA Motion Stretch Deformer did. Really grateful for this amazing C4D community. Glad to be here !
