If you have photoshop, as long as you have the alpha map intact, you can go to channels ctrl+click alpha channel, click the all channels,then click and drag the selected to a new image with nothing and save with photoshop to a .gif or something. I don't see why you would need your movie to blend in with the background of your website.

Okay, yes -- but you need to buy another piece of hardware (well... software... but the word hardware seemed to sound cooler)... Quicktime Pro

When you save out your frames, save them out in the Targa format, then string them together using Quicktime (I'm not sure if Maya for Mac has Quicktime export with alpha channel) saving the color depth as millions of colors+ -- the plus is the alpha channel.

Quicktime Millions of Colors+ can be opened by various programs like After Effects, etc. You'll need to know a bit of terminology they use though.

Remember to set as Targa frames with Alphachannel in the render globals!!! :b

ooooooooooooook user added image

well. the reason i need the background transparent is because im doing the site in layers. and i want the background picture to show as if the logo thats rotating is just in front if the background. and having the background transparent i can place the logo where ever i would like on the site. with out getting a bounding box or having to have multiple logo rotation pictures. which saves load time and space. user added image

as for photoshop i do have that program version CS i belive. but i dont know it vary well. i whish there was a way to set background transparentcy in Maya as i know there's a flash Export as thats what i will be using to animate the logo. i will try your Quick time idea. hopfuly i works and i do it correctly. :bored:

Just go into Render Globals and make sure the "alpha" check box is ticked for the object. Then, render out the image sequence as tiff or tga. The final step would be importing the sequence into a compositing application such as videomach, after, effects, shake, etc. where you would add all the various layers and output to a final movie format. You might want to check out our Render Globals video that goes into all the RG settings as well as rendering out the images and bringing them into the free video editing app, videomach. You could Also check out Rage's Intro to Compositing tutorial which is another good one. Both are in the video tutorial archives.
