Researching Perception Neuron Suit Kit for Unreal Engine Interaction

Renting a kit on Monday May 10th to test interaction capabilities

Link to Axis Studio

Product Tutorial/Review

Plan for using Kit:

Step 1 — Set Up Axis Studio

(supports PC)

1. Install and open Axis Studio (Noitom's free capture software)

2. Put on your suit and connect it via USB or Wi-Fi

3. Complete the initialization poses when prompted so the software calibrates the sensors

4. Go to Settings → Output Format and disable Displacement — this is important or your character will drift PERCEPTION NEURON

5. Go to Broadcasting and enable TCP or UDP (both are supported, with minor setup differences in Unreal) PERCEPTION NEURON

6. Enable Capture, Edit, or both — Capture is for live data from your suit, Edit is for pre-recorded data PERCEPTION NEURON

Step 2 — Choose Your Skeleton Preset in Axis Studio

This matters because UE characters use a different default pose than Axis:

• Use Axis Studio Skeleton if you are broadcasting to a character in T-pose, or Unreal Engine skeleton if broadcasting to an Unreal character in A-posePERCEPTION NEURON

Most UE Mannequins and MetaHumans are A-pose, so choose the Unreal Engine skeleton preset.

Step 3 — Install the Neuron Live Link Plugin in Unreal

1. Search for the Neuron Live Link plugin in the Unreal Marketplace and add it to your project PERCEPTION NEURON

2. Inside your UE project go to Edit → Plugins, search for "Neuron Live Link" and enable it

3. Restart the editor when prompted

Step 4 — Connect Live Link in Unreal

1. In the UE Editor, go to Windows → Virtual Production → Live LinkPERCEPTION NEURON

2. Click + Source → Axis Neuron Live

3. Match the local address and port numbers to what you set in Axis Studio — if using UDP keep "Is UDP" checked; if TCP, uncheck it PERCEPTION NEURON

4. If connected successfully, the Subject Name from Axis Studio will appear in the Live Link panel — it will match the character name in Axis Studio PERCEPTION NEURON

Step 5 — Apply Motion to Your Character

1. Open your character's Animation Blueprint

2. Add a Live Link Pose node and connect it to the output

3. Set the Subject Name to the one showing in Live Link

4. Choose the correct Remap Asset — this is critical:

• Neuron Remap → for Perception Neuron / PN Pro rigs

• Studio Remap → for Studio Skeleton and Mixamo rigs (without "Mixamorig" prefix)

• UE Mannequin Live Link Remap → for CC3/third-party characters

• Mixamo OLD Live Link Remap → for Mixamo characters with "Mixamorig" prefix PERCEPTION NEURON

5. Compile and Save the Animation Blueprint

Step 6 — Test It

• Press Play in the UE Editor

• Move around in your suit — your character should mirror your movements in real time

• If the character is frozen, double-check that Axis Studio is actively broadcasting and the port numbers match on both ends
