As we don't have it (yet?), is there a tip for composite them?
I add the environment in Photoshop, with the help of the Alpha layer, but i don't have it in reflections

Why don't you make an mxi for bg and reflections?

i couldn't produce the spherical map from the photos...

What I do is use an mxi made from a photo for the background and also create an emitter material with that mxi and apply it to a curved plane in the scene. I have done this before for window reflections.

Thanks Bubbaloo, i often use it too, but that time the great solution would have been the perfect spherical map, cause i render tons of different cams a day...
I hope i'll find the spherical map creation tip... or buy a SphereCam!

Have you tried converting your image to HDR then converting it to spherical using HDRShop? I've never tried it, but I know it's a function of HDRShop.

sorry for the late reply, thanks for your help!

I'll take a look at HDRShop, its help file surely explains how to prepare the initial photos.

If you have Photoshop CS3, you can use the Photomerge tool in the filer menu, to create you spherical maps.

File>Automate>Photomerge.

This is a good solution although not the best. A stitcher software will make things even easier for you.

Check out Autopano Pro if you decide to go with a stitcher. I switched to that one recently and have been very happy with it. As far as I know CS3 does not actually "automatically" create the correct format for spherical maps, but maybe I just couldn't figure it out.

My tip for compositing reflections in MW would be to render your reflective object with no reflections, or minimal ones, and then re-render the object with a black highly reflective material, and then composite that version on top using something like linear dodge in Pshop. That gives you a pretty effective reflection "pass".

Thanks for your help, i couldnt read them sooner, sorry
I've used photomerge to mix the "left" and "right" sides, but my pb is really to make the good spherical map from them...

again: I think you need a stitching program of some sort. Photoshop does not do the correct projection mode for spherical maps (as far as I could tell at least).

I set up an action to show the old school way of creating a spherical map with no pinch at the poles. It doesn't beat a Spheron but it's the way people always did it before stitching software.

It's a Photoshop Action. Go to your Action palette and click the down arrow to select "Load Actions". Then open your image, run the action and follow the instructions that come up.
