PopcornFX "light renderer" size not expanding properly in o3de.

[CarbAndrewD]

When using the PopcornFX gem for particle effects and using a particle with the "light renderer" node, the point light's range only shows sizes from 0 to 1 meters. Anything above 1 meter doesn't show a larger light.

PopcornFX (our project uses 2.17.4, but I haven't seen any changes to the light renderer in any of their updates since)

Steps to reproduce
-Create a particle effect using the light renderer node.
-Set the light attenuation sharpness to 1, and the range at any value above 1.
-Make a control light node(s) with a range value at (or at varying values under) 1.
-Load into o3de and enable the new particle effect.

Expected behavior
The range value should correspond with the radius of the light in the set o3de measurement units. A range of 5 should create a light with a radius of 5 meters (or whatever unit is selected)

Actual behavior
The light radius matches the range value from 0m to 1m, then caps at 1m. Anything above that does not show a change.

My recommendation is to engage with PopocornFX to do a quick pass to asses if the issue is with PopocornFX or O3DE. There repo is https://github.com/PopcornFX/O3DEPopcornFXPlugin/issues.

I reached out to the PopcornFX team about a week ago. They were not aware of anything on their end which could be causing this issue but are also looking into it.
