#UnrealEngine5.6 has a "Locomotor" plugin which provides a new #ControlRig node for procedural locomotion. It takes a target position as input, and outputs an array of feet transforms which animate over time to step towards the goal location. Pelvis motion is also generated. 🧵1/4

This is procedural animation in #UnrealEngine 5.7, using a Control Rig running a Locomotor to generate footsteps, and the new Control Rig physics to drive the pose to the target step locations.

Finally got my hands on PolyGen 1.5 and HunYuan 3.1. Big improvement over Meshy 6 on my single-image Ninja Frog test. Sharper edges, better adherence to the concept. Some hallucinated props on the back side (expected with single image). The retopo looks like a very good first pass. Haven't brought into Maya yet to see if it's full of surprises though.

New "Meshtron" paper from Nvidia produces "artist-like" meshes from point clouds. This is huge for producing useable assets from scan data or text-to-model diffusion systems. Could even be a powerful retopo tool for artist modeling workflows.

In this video I demonstrate #UnrealEngine5.4's brand new workflow to automatically retarget animations between common skeleton types. This tool makes it super easy to bring your animation into Unreal from outside sources. With just a few clicks, you can transfer animation two/from most industry standard skeleton types (Mannequins, Mixamo, Motionbuilder, Xsens etc...) with support for root motion and IK bones. If you want to make simple edits to the resulting motion on your character, you can optionally auto-generate an IK Retargeter to tune as desired.

There's a whole generation of animators that haven't studied Purple and Brown shorts. Masters of comedic timing, body language and visual storytelling.

Here's some more wolf abuse😅 This time, a pathological ground alignment test for the Locomotor in #UnrealEngine 5.6. The Locomotor is generating steps towards the green sphere that I'm dragging around with the mouse. Input pose is playing an idle animation, and feet positions are solved with FBIK.

I've got a lot of questions about how to drive a Locomotor in on a character in a level. This video overview demonstrates how I setup a little terrarium full of patrolling scorpions.
