UAV1 and UAV2 topic dose not work

I have same problem blow. I set up with iris_fpv_cam.

I can’t arm uav1 and uav2 and get topic information.
but I can arm uav0.
Somebody help me.

@KENTA_OKAMOTO Currently iris_fpv_cam and other derived models are not supported for the multivehicle simulation. Can you verify that it works for the supported models such as the iris?

Thank you for your notice. I’ll try this.

@Jaeyoung-Lim What happens if we force the iris.sdf model to have the content of iris.sdf plus a new camera, and then we run the launch file for multiple uavs? Should that work?

@Jaeyoung-Lim I have the same question!

@joaquinvalentin I already answered to the original question above
