Wouldn't it be easier if the shadow channel was black+alpha instead of black+white.
I don't fancy compositing and I keep coming up with whitish halos around my shadows.
The "embeded alpha" option really made my life easier, so why not push the idea all the way ?

How are you compositing it? With Multiply it shouldn't give you any white halos.

Hi Mihai,

I'm using Gimp.
Thanks for the "multiply" tip. It's exactly what I was looking for.
No need for Alpha here.
I guess I'll have to find "Gimp for Dummies".
Or are there any simple online tutorials that you would recommend ?

Cheers,

Errr... Finally, I think my suggestion makes sense :
If I composit using "multiply", I end up with a white background that I have to take out.
So again : why white instead of Alpha ?

Any help on this compositing issue ?
Mihai's trick just got me half-way : now I can composit my shadows and my render properly, but I'm still stuck between the shadow and the background.
Wouldn't it make sense to output Shadow+Alpha instead of Shadow+White ?
Thanks,

hallo,

maybe you should try to convert this pass as a chanel in PS as you would do for alpha

Good luck hope this help
