Issue with the latest commits in RapyutaSimulationPlugins and rclUE

[gabz144]

I recently stumbled upon an error when trying to make a new project on Unreal Engine 5.5.4 using RapyutaSimulationPlugins and rclUE.

Firstly, I'm being told that both plugins are built with a different engine version which wasn't the case beforehand (see the image right under)

And then, after I click Yes, it seems to be compiling but I get the following error at the end :

LogInit: Warning: Still incompatible or missing module: rclUE
LogInit: Warning: Still incompatible or missing module: RapyutaSimulationPlugins
Project could not be compiled. Try rebuilding from source manually.

Software versions :

• Ubuntu 22.04
• Unreal Engine 5.5.4 for Linux (downloaded on the official website)
• Ros2 Humble
• RapyutaSimulationPlugins cloned into the Project's Plugins folder from the git https://github.com/rapyuta-robotics/RapyutaSimulationPlugins (put on the UE5.5 branch)
• rclUE cloned into the Project's Plugins folder from the git https://github.com/rapyuta-robotics/rclUE (put on the UE5.5_devel_humble branch)

How to get the same issue :

• Create a blank Simulation C++ Project in the Unreal Editor
• In the project folder, create a new Plugins folder and clone both Rapyuta and rclUE inside
• Change the branchs on both plugins to be on UE5.5 for Rapyuta and UE5.5_devel_humble for rclUE
• Try opening the project again from the Editor

What is causing the issue :

Since the plugins worked well before, I tried checking out to previous commits in the plugins and it worked well so this issue has something to do with the latest commits on the branchs.
It worked well with the following commits :

• 9683598 from Feb 24, 2025 on the UE5.5 branch of RapyutaSimulationPlugins
• ce236ae296f903c513ad50ce5c9bb232365dd0ca from Feb 9, 2025 on the UE5.5_devel_humble branch of rclUE
