Particle system not looking that good in unreal editor's viewport

I am new to cascade editor and i have recently started to acquaint myself with it. And so i was building this particle system, but i seem to find this issue that my particles don’t look that good in unreal editor’s viewport as they look in cascade’s viewport. For better visual explanation on my problem, i have provided these images:
