PointCloud2 topic not displaying

[Jaetriel]

Hey, I downloaded the project today and ran it on Unity 2020.3.3f1. I connected to a different PC that was running a SLAM algorithm on ROS and wanted to visualize the generated point cloud using iviz. The topic I need showed up and I chose it, but I didn't receive any messages on it. I even tried disabling the firewall and echoing the topic in iviz but still nothing. The PC running Unity is running on Windows 10, and the ROS-running PC is on Ubuntu 18.04. Any idea what I might be missing? Thanks
