I’m Roland Hartmann – Houdini Generalist & 3D Motion Designer based in Linz, Austria.

Growing up with Star Wars, Star Trek, and a skateboard under my feet, I’ve always been drawn to visual effects and creative cultures. With more than 20 years of experience in video production and motion design, I now bring that same curiosity and energy into my work as a freelancer under the name Node Connector – specializing in simulations, fx, and procedural workflows in Houdini.

My journey took me from camera work and editing, to motion graphics in After Effects – where I became an Elite Author on Videohive, publishing 80+ motion graphics templates used by creators worldwide – and finally into the world of complex 3D and FX. Along the way, I learned to bridge creativity and technology: structuring complex processes with clarity and turning them into strong, visually compelling results.

For studios, agencies, and brands, this means working with a remote freelancer who bridges creative ideas and technical precision – ensuring that concepts turn into reliable, visually striking results.

Alongside client work, I’ve published 125+ tutorials, built a YouTube channel with over 100k followers, and share in-depth Houdini training on Patreon – a commitment that keeps me sharp and connected to the community.
