Volumetric Inferno Flames

zeppers

I bought the Volumetric Inferno pack but for some reason, when I use the flames + materials provided, they all come out really dim and smokey and not like the promo images. Am I doing something wrong? Would appreciate any help, thank you. The second image is when I tried upping the luminosity but I still didn't gain the same result as the promo image. I am sort of new to daz so I may be missing something.

What is your setting for Enviorment Mode in render Settings - it needs to include Scene in order to see emissive surfaces.
