I know this type of question has most likely been answered many times, and there are likely many great tutorials out there. Sometimes it is easier if someone translates information for me, so please be patient and kind. Let's use the Canoma Bedroom for this example. In the first picture, I'm showing a rendition using Bryce.(I've barely begun to fiddle with Bryce, so I'm not likely ready to do much with it.)

Now let's import the bedroom into Poser. I don't know how to answer all the questions, so the only thing I did was check Place on Floor. Did I make the right choice?

The bedroom came out rather small, so I fiddled with the camera settings to bring a closer view.

This is the resulting view, with the main camera zoomed in for a closeup.

Now this is where things get interesting. In this case Vicki looks like a giant. I've tried fiddling with the scaling dials, and always came out with a bedroom that was so warped out of shape that I eventually gave up. Now is your chance to show off your knowledge and abilities. How do I bring the Canoma Bedroom into Poser, and give Vicki another great room to relax in? And how would I manage to bring a bed in there, and have everything be proportional?

first : in the importdialog there is "percent of standard figure size" set it to 300 or 400. Second to change it , use the scale -dial to make it bigger. dont change viccys size, the clothes wont fit anymore. I always use a poserfigure to get everything in the right size.

I tried importing the bedroom at 400%, and it looked a bit small. So I imported it at 450%. This is the result. Does it look decent? (I had to "save for the web," since my original file size was apparently too big for Renderosity!)

Maybe I'm getting the hang of this? I tried the Canoma Kitchen this time, and imported it at 400%. The only big problem I see with this render is that Vicki burst out of her shoe straps! Other than that problem, she can cook in my kitchen any day.

the easiest way is to import room at just normal size load figure,select body and then scale down until required size cheers dolly

looking better and as dolly, says scale it till it fits.and
viccys shoes have nothing to do with the kitchen.
by the way,no need to import the kitchen.viccy is very bad
in any kind of cooking,washing ,ironing.no work in the
garden , nothing....ONLY NEW CLOTHES EVERYTIME THERE IS
SOMETHING NEW IN THE STORE

don't scale the person. scale the bedroom to the person. after you've done this select the room prop and save it to your library. Otherwise if you bring in someone else you'll have to scale them too, then the furniture, etc. etc. I find most things are scaled to the people. Unless they are really huge or really small or have nothing to do with people. By the way, did the model come with Canoma? I hope so!

Yes, I agree, it is easier and makes more sense to scale the prop as it's being imported. If you try resizing the person, you're dealing with the x,y,z parameters, and you need to worry about the clothes etc. As for the model?! I'm not sure what you mean. The Canoma Kitchen and Bedroom were from Poserworld. I checked the readme file. There were no details as to the origin of the "set." I downloaded them months ago and finally figured how to use them. The woman is Vicki, from DAZ, as you likely know.
