Overview:
Testing the workflow of cross-device data transmission from an OptiTrack motion capture system to Unreal Engine 5 or TouchDesigner.
1. Hardware Connection
Use an Ethernet cable and an adapter to connect the two computers directly.
2. Network Configuration
After connecting, the system will show “Identifying” and then display an IP address.
Since there is no DHCP router, manually assign static IP addresses:
School computer: 192.168.1.1
Subnet Mask: 255.255.255.0
Personal computer: 192.168.1.2
Subnet Mask: 255.255.255.0
Leave Gateway and DNS empty.
3. Connection Test (Ping)
Open Terminal (Win + R), then ping the other computer’s IP address.
If you see “Request timed out”, check firewall settings:
Win + R → wf.msc
Go to Inbound Rules
Enable:
File and Printer Sharing (Echo Request - ICMPv4-In) (enable both entries)
Alternatively, use command line:netsh advfirewall firewall add rule name="Allow ICMPv4" protocol=icmpv4:8,any dir=in action=allow
综述：
基于optitrack的mocap设备跨设备数据传输与UE5或Touch designer传输数据的流程测试。
1.先用“以太网线”和“转换器”把两台电脑连接
2.然后会出现identifying随后会显示ip地址
更改为手动设置静态IP（没有DHCP路由器）
学校电脑：192.168.1.1，子网掩码: 255.255.255.0
自己的电脑: 192.168.1.2,子网掩码：255.255.255.0
Gateway，DNS留空
3.打开terminal（win+R）ping 对方电脑IP
如果Request timed out，则需要检查防火墙设置
win+R
wf.msc
入站规则
文件和打印机共享（回显请求-ICMPv4-In）
右键启用规则（两条都要启用）
根据Claude的建议可以：netsh advfirewall firewall add rule name="Allow ICMPv4" protocol=icmpv4:8,any dir=in action=allow
4.当看到Reply from 192.168.1.2: bytes = 32 time = lms TTL = 128
ping statistics for 192.168.1.2:....
就意味着两台电脑连接成功了。
