Hey Epic,
As of September 26, 2024, IsInVolume() is still not supported for Volume Device.
While it is possible to achieve similar functionality using Mutator Zones, this approach imposes unnecessary memory costs on projects that are implemented based on Volumes. Additionally, if we implement the functionality based on Mutator Zones, there is a risk of human error, where team members may unintentionally modify the parameters of the Mutator Zone, leading to stressful situations.
I would greatly appreciate it if you could reconsider this request.
