Motion Blur of Dynamic Meshes in Cycles


Greg Zaal reports on a new upcoming feature that supports motion blur for meshes that change structure or vertex count. The feature is already in the Master branch, so you can download a nightly build from the Blender Buildbot.

Kévin Dietrich has been working on something I didn’t even know was possible: motion blur support for meshes that have a changing number of vertices, like fluid simulations.

We’ve had motion blur support for dynamic meshes in general for a while now, but that was only for things like characters with an armature, or anything where the vertices in a mesh move around.

What this new patch does is add support for cases where the mesh structure itself changes, when new verts and faces are created or removed.

I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.

    Yes! I've been waiting for this! You can get some great looking results with Blender's fluid simulation for animations, but I've gotten so used to Cycle's great looking motion blur that it's hard to go back to using vector blur. Vector blur is fine, but just looks odd used on fluids somehow. This is a great step forward for fluid simulations in Blender!
