#Disk Render Alpha only
6 messages in this thread
Greetings All,
I am wondering if there is a way to have 3DSr3 save only the rendered .TGA
alpha files to disk as opposed to split image and alpha?
What I'm doing is generating animated hi-con mattes for later (video) on-line
posting. The alpha images are all I really need so I wanted to save myself
some file upkeep and mucho disk space all at once.
Thanks,
Paul
Paul, If you use a custom directory to save your images and render from Video
Post you could call a batch file everytime you render an image that deletes the
non alpha .tga from the directory. There isn't a way to just render the alpha
channel so you'll have to do something like this. Because the alpha images
always start with A_ you could just have your batch file DEL IMAG*.* and only
non alpha files will be deleted. Should be very easy to accomplish this way.
Good luck.

In addition to what DavidM said, there's actually a way to do this. Download
the alpha.ixp from DL1 (I think it's called alpha.zip) and use that as the last
entry in your VP sequence. It'll strip the RGB off and should let you save
just the alpha.

Great tip about using Alpha.ixp in VP. Why didn't I think of that?

Thanks one and all for the tips.

Sure, in the IPAS data library you'll find ALPHA.ixp (in ALPHA.zip). Use this
in the keyframer from Video Post and make it your last entry in the VP queue.
Render from Video Post and of course turn ALPHA ON and SPLIT off. This will
create the same files (only 24 bit not 8) as SPLIT does.
