Reducing GPU memory usage for multi-camera uses

I’m currently trying to simulate 8 or so cameras at once while having them all publish with ROS. However, it seems like doing so causes my GPU to run out of memory (RTX 2080, 8 GB). I’ve found that I can get up to around 4 cameras working at the same time, using up ~7.2 GB. Are there any methods for lowering the memory usage for many-camera use cases?

EDIT: I thought I should mention that I am effectively only using the cameras for ROS. If there’s a way to disable them rendering to viewports while still updating in ROS, that might also help.

Hi wchen,

We are aware of the memory usage of the multi camera, and also about the limitation that the camera is tied to the viewport. We are working on it for the next release.

Kindly,
