2sided plane with no translucency

Hi, im stuck how do i achieve this? double sided material like 2 texures on each side or 2 materials one at each side? vray2sided with translucency black or white doesnt seem the same. ty

Falloff map with Towards / Away type and stepped Mix curve could do the trick - here is a quick example:

I can’t try it right now, but does the standard Double Sided material work with v-Ray?

Thank u !!
