Hi Doc, Thanks for the question. No it's not geared to people who dont have these programs. I use Bryce myself and as you know you cant really animate a figure in it, also you cant pose a figure in it really unless you kind of set up the figures pose in Poser first then export it. So 3d Worlds Kit is made for Poser in that you can use all the power of Poser and it's characters in a real 3d environment, this is the major difference. Personally I hardly use Bryce anymore, its a fantastic app and I love it, but as I said you cant get Poser figures to run around in it, even if you could, you still have to export and goof around to get it happening, this is all right inside POser. Other differences are Bryce is a lot more powerfull because it has Terrain generators and sky generators and so on (so is Vue De Esprit) This 3d World Kit has better looking skies than Bryce though (because they are real sky maps mapped on a huge illuminated dome) and they look and respond in a very real way. The ground has subdivisions and a different type of mapping which makes it also look very real, as you can see from the images. But Bryce has material generators that tile fractal patterns over an infinite plane and this is very versatile,. but often does look very real up close. The Poser 3d Worlds relies on maps or skins (like we use on Mike and Vicky) now this is a lot less versatile but a lot more realistic if done properly. I am hoping that if it gains momentum that some of the very talented artists will do more grounds and sky textures for it, currently in the main kit there are 2 main gound themes...sandy and grassy (autumn-leafy grass also grass and asphalt path and plain grass)and ten sky themes. The potential to build on this is enormous and as I said earlier the main difference is that it is right inside POser. Hope this helps Harvey Mann
