Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

Alpha Channels

I am working with maya 5. I have a little problem with my rendered output. When i take my renderings into a compositing software like AE, it doesn't recognize the alpha channels. I had checked the Alpha option in the rendering globals window and I have tried it with IFF and AVI formats. Am I missing something or is this a bug?

Actually, AVI work with alpha. I have done an alpha rendering from AE and used it to remove the background in Premiere. It works. The problem is the maya render.

I am not sure whether i tried it with mental ray. But I have tried it a lot with maya software.
I haven't tried it with the targa format. I like AVI because it is supported by many software. I like IFF because it is the default rendering option (just kidding).
I am not a professional and I did not learn computer graphics from people. Most of what I know is through experimentation and my experimentations have shown me that AVI work with alpha.

I was just going to say that with MR you can have problems with alpha channels if you dont set it up correctley.

I have used the alpha in a AVI file but i'm not a big fan of it as I have had problems with it in the past with some softwares. (with After effects to be honest)

I personally render it as a series of TIFF's and let aftereffects import it as a image sequence, and I have had to date no problems so far.
