Greetings, I have a very annoying Problem when i add a backgroundpicture in poser. Whenever i add a pic that is e.g. 800 x 600 poser askes me if i want to resize the window to match the background. I click yes and in the preview all looks fine, but as soon as i do a firefly final render, the background picture is compress to the former size of the preview window... any idears why that is so?

Don't know why that is happening, but here is a trick to help you out. Add a square primitive to the scene. Apply your background image in the Mat Room to it. Then you can resize the square to fit in your scene.

Another way is to save the render with an alpha channel, like Photoshop's PSD, and composite it in Photoshop.

Another note re. destro's advice: If you go that route, there are a few things you can do that may help things along: - Scale the square so it has the same size (in poser units or whatever you're currently using) as the picture is in pixels (that'll retain the pic's proportions). - Use a single-sided square (not the 2-sided one). - Move the square waaaay back in z to avoid casting shadows from the foreground onto it. Plug the image into the ambient channel, not the diffuse (you don't want it affected by the lights, do you?) - Use the main scale (not scale x or whatever) dial of the square to get it to fit. You may also have to rescale your display window and/or render window. Cheers, Diolma (I've probably left something important out, it's a habit of mine..)

Dammit, I knew I'd left something important out...
Turn the diffuse colour off completely (make it totally black or set the value to 0) -- errm, or is it the other way round? Make it totally white.. I think it's black, long time since I did this (at least 2 months ago)..

Cheers,
Diolma
(Wonder what else I've forgotten..)
