How many cameras could be added by json?

I add 4 cameras by edit config&graph json files, but UE4 crashes when click play, and the log says Display: START BRIDGE WITH JSON COMMAND LINE. However, when I only add 2 cameras it works well. But I once added 4 cameras successfully before. I don’t know why. Does Issac Sim only support 2 cameras?

Hi Fleur,

There shouldn’t; be any limitation in the number of cameras, but keep in mind any camera that you add it will drop the performance and the fps.

Thanks a lot. And now I find if I delete the publisher of a new camera, the engine will not crash and I can add more than 2 cameras in a map. That’s really confused.

Hi Fleur,

You are right, that is confusing and strange!
Thanks for informing us. I will ask the team to investigate this.

THanks,

Hi Liila,

We have found it maybe not camera’s problem. It seems like if we add more than 14 nodes in json, ue4 will crash. But we can’t get more information because it is packaged in a .so file. Maybe it would help. Thanks for your attention.

Hi fleur002,

Thank you for the interesting observation, we will check this out.

Thanks,
