Does it import poser 4 very easy? Does it have better water textures? Does is do waves and waterfalls? Is the sky lab like Bryce 4 (fog, haze, tons of sky options, rainbows, sun and moon positions? What makes this better than Bryce 4? Is it worth the money to buy Vue 3 if I have Bryce 4? What enhancements does it offer? Thanks!
