I wondered how that pool would render. May I suggest a water pack to go with it, for those different feels? Maybe a frothy/magical one, a lily pond one... I believe I might be able to render you a few, if you like.
I wanted lily pads!!! How did you know??? Sure, render a pack for it!!
From what I've read, the water renders better in Poser 6, however I haven't checked to see if there is additional water textures for the pool lol.
There don't appear to be any other "DAZ" textures for it. Think I should do a cut-out type to lay in the spot, post-render? I'm sure I don't know how to do an actual "texture"for it. I could do a pack for you to try it though...
Are you trying to do a water texture for the pool? I think Daz had a template download on the page where you order the garden, download load it and open in PSP or Photoshop, use your wand tool to outline the water part of the template (if it's there, I haven't looked), create a new layer and fill with the new texture, delete the template, flatten and then save as jpg, name it something like MGwatertx1 & place it somewhere in Daz>Studio>content>Runtime>textures where you can find it when you go to Surfaces and apply manually.
