HiCarmen, there is a set at Renderosity called Sandworld-Oasis by 3-d-c that you could check out, it has a sand terrain and even a water pool. Maybe this would suit your need, have a look.
Thanks I got that and a lot of other deseret sets around but the one that i need is at DAZ and only for D/S! Kills me but that's what it is. If only the creator had also created a Poser version or even a simple 'obj./3ds version with textures i would have jumped through hoops to get it.But Nooooooooooo!
