Cannot increase draw distance of particles

For some strange reason I can’t seem to increase the draw distance of my particle system. I’ve tried adjusting the Fixed Relative Bounding Box, but it seems to be hard coded to delete the particles once you get a certain distance away from them. I’ve even tried scaling the particles in size when you get a certain distance away from them using a blueprint and some collision spheres set to increase the scale on end overlap (which is working) but even at the larger scale, once you get X distance away from the location of the particle system, it removes them from the scene. I’d like to be able to increase this value but I don’t know where to find it as all the research I’ve done says its the Fixed Relative Bounding Box that determines this. I’ve tried using all sorts of values for the min and max FRBB sizes (as high as 8192000) but it doesn’t seem to have any affect on when the particles get culled. I’ve also tried increasing the LOD Distance value as high as 81920000 but this also has no affect.
I’m using a static mesh in my particle emitter and I’ve also tried to adjust the screen size lod scale on the mesh as well but this also doesn’t work.

I’d love to know how to increase the draw distance of my particle system.
