Hello Oliver,

If PFTrack is hanging at random moments that usually points to an issue with the system rather than PFTrack itself. If the message you are seeing is saying PFTrack is not responding, this may indicate it's waiting for something to finish, which can happen if something else is slowing down or blocking access to your disk, network, or another system dependency, especially if you're using network attached storage for either your projects or media.

A good first step on Windows is to reinstall PFTrack because this also makes sure the correct C++ runtime library is installed. This library is shared between different software and can sometimes be overwritten by other applications which leads to stability problems.

If the problem continues, check the PFTrack log file or the command-line window for any hints. And as @buddhaboy01has helpfully suggested, try to notice any patterns. Knowing how often the hang occurs, and how long PFTrack has been running before it happens may also help. That information can help narrow down whether the issue is related to system stability, storage, or another part of your setup.

I have yet to have anyone from Pixel Farm get back to me. I have posted a couple times in the past and never got an answer. This 'omission' of functionality needs to be in BOLD print for users so they can decide which edition they want to purchase once they decide to move away from subscription model. I would like to know personally how much extra I need to pay to get the photogrammetry tools, Spherical, depth extraction, mocap solver (thx to buddhaboy01 for finding these extra missing nodes)... It was only apparent to me when I loaded scripts from my subscription edition into Solo and the nodes were 'UNKNOWN' all of a sudden. Pixel Farm - do the right thing and please let us have some of these functionalities back. I am really bummed about not being able to extract a mesh and UV texture of the environment. To me PFTRACK has lost 25% of its appeal... :(

Hi Angel,

It’s worth double-checking that the user tracks you want to solve with are actually enabled in the Camera Solver. In the 25.11.13 update, the workflow was adjusted to give more flexibility over how trackers are organised in the node tree. Because of this, there’s no longer a single unified “camera” group for all tracking points, tracker nodes can now be toggled on or off individually depending on what you need for a given task.

In the Camera Solver, you can choose which tracker groups to include. For example, in my setup both Auto Track 1 and User Track are enabled, so they’re both used during the solve.

After solving, you should see the enabled tracker groups listed in the Scene Export node at the bottom.

Hello Tomas you can find the information you need here: https://pftrack.thepixelfarm.co.uk/documentation/pftrack_network.html

We acknowledge the need for a single, comprehensive tutorial, especially following the updates from last week.

PFTrack’s distortion tools are undergoing a major refresh that will be completed in the new year, and we’re working hard to integrate these changes. Because of this, a full tutorial covering the entire updated workflow isn’t available yet, but we will absolutely provide one once the transition is complete.

Concurrently, we’ve just introduced the brand-new AI help tool in the latest release. The AI assistant provides instant, context-aware guidance, allowing you to ask targeted questions about features, workflows, and best practices. This on-demand support makes it easier to explore new features, adapt to workflow changes, and access the information you need quickly and efficiently.

We strongly recommend you give this a try as we plan to extend these types of tools to offer a more individual user experience focused on your own personal needs rather than generalised support materials such as tutorial videos.

You can access the AI help tool through the Help menu in the application.

Hello Olivier,

You can find the pricing and additional information about the different versions of PFTrack on the new PFTrack website: www.pftrack.com. The discount for a perpetual licence will be applied automatically at checkout. Further information has also been sent to all users via email.
