A mini rigging-and-motion stack for splats: Infectracer extracts/grows spline skeletons, Wind gives them believable gusty motion, and Looper turns the result into clean, reusable cycles.

LMI Infectracer

Infectracer is built for one thing: intricate propagation simulation, fast to set up for simple growth effects, but deep enough to produce complex, organic behaviour when you need it.

At its core it’s a propagation solver, but the real magic comes from the Tracer module: a secondary simulation layer that turns clean “spread” into natural-looking growth: branching, crawling, wrapping, and evolving in a way that feels alive rather than procedural.

Beyond cool visuals, Infectracer has a very practical role in our Gaussian Splats pipeline. It can be used to derive a skeleton from any splat, for example, our tree splats. Giving you a controllable structure you can rig and animate, including wind-driven motion. You can take a scanned tree splat, extract its skeleton, and bring it to life.

LMI Wind

Wind is a follow-up solver designed to bring motion to spline-based structures — especially the skeleton splines generated by LMI Infectracer, but it works with any splines that carry compatible attributes.

It solves believable wind-driven movement with natural bounce, settling, and gust behaviour, giving you an easy way to add life to branches, stems, and lightweight organic forms without running a heavy simulation stack.

This is the first iteration of the tool, so it’s not aiming to be a physically perfect, vellum-grade solver. The goal is speed, control, and good-looking motion. A practical wind pass that’s “right enough” for production use and iteration.

LMI Looper

Looper is a simple tool that ends up being used everywhere. Feed it any animated geometry or curves with a constant point count, and it will turn that motion into a seamless loop.

It shines when the animation has calm, more “cyclical” changes and for the right kind of motion it can look completely perfect. A classic example is wind movement on branches: run your sim, loop it cleanly, and you instantly have infinitely repeatable motion for shots, turntables, or library assets.
