Setup
— How to install the plugin?
Place the contents of the downloaded ZIP file into your Houdini packages directory:
– Windows: C:\Users\<Username>\Documents\houdiniXX.X\packages\
– macOS: ~/Library/Preferences/houdini/XX.X/packages/
– Linux: ~/houdiniXX.X/packages/
If the ‘packages’ folder doesn’t exist, simply create it. Check out our video guide for a step-by-step walkthrough.— I downloaded a DMG file on macOS, where are the files?
Double-click the DMG file to mount it – you will find the installation files inside. Use them as described in the guide above.
Tracking
— Do I need a 3D model to track with GeoTracker?
Yes, GeoTracker is a geometry-based tracker, so you’ll need a 3D model to start. You can use any model imported or created in your Houdini scene. By the way, if you don’t have a model, you can quickly generate one from your footage using tools like SAM 3D.
— How detailed should my 3D model be?
More detail usually leads to better results, but balance is key. Very high-poly models can be resource-heavy.
— Does the 3D model need to perfectly match the real object?
Ideally, yes. However, GeoTracker is smart enough to track a car using a simple cube. Primitives work great when precision isn't critical.
— Can GeoTracker handle occlusions or reflections?
Yes. To handle complex shots with heavy occlusions, you can use Surface Masks to exclude specific areas of your model from the tracking.
— Do I need markers for tracking?
No, you don't need anything like that. But having markers can improve tracking results because they'll work as distinct features that are easy to follow.
Licencing
— Is GeoTracker free or paid?
GeoTracker is a paid plug-in with a 15-day free trial period with no limitations in its functionality. Monthly and annual subscription plans for individuals and annual for studios and teams are available through the Buy page.
— I bought GeoTracker for Houdini. Can I use the same license in Blender, Nuke or After Effects?
No. In order to use GeoTracker on other platforms you’ll need separate licences for those platforms.
