Thank you for clarifying your own set up as it has helped me get some results on my end, however I am getting some irregularities with the movable point light at specific distances and not seeing the culling of the particle effect using ‘Fixed Relative Bounding Box’.
Instead of me trying to reproduce this in a project of my own, and the potential of not being able to get the issue to occur. Would you be willing to share your project with me via a google drive link or dropboxx link? Even better, if you are able to reproduce this issue in a new blank project with some simple steps, you can provide me with that instead.
All you need to do is zip up the Content, Config, and .Uproject into a folder and share that with me via an external folder sharing application like google drive or dropbox as mentioned earlier.
Thank you,
