How to..?

[Mohamm3D]

Hey guys, im pleased to say octane is awesome! hehe im sure you all know that already .. Im currently modeling a bugatti veyron in 3Dsmax and
hopefully i will render an animation with octane <3 ive seen the animations on the octane site's gallery i particularly like the lexus concept and
i wanted to do the same thing i noticed the ground was reflective, how would i achieve this? and i tried putting an environment hdri map but that
takes away the light , how would i have both of them together? and is there a way to put the ground via octane? or do i have to import all objs?
I hope im making sense guys.. i'll keep everyone posted on the progress of my model. thanks for all your help , oo how do i get rid of those sprinkles of white??
