masking out part of a material for compositing
Hi
I am rendering out a globe.
So I have one big world texture on a sphere.
I need to composite in a plague spreading across Africa.
So I have a mask for the parts I need.My question is where do I put the mask in C4D so that I get a mask in the multipass.
If I put in the alpha channel of my material it cuts out part of the map.I have been at this for days, can somebody please help.
Thanks
Jake

I would create the alpha and then do a separate render with just your globe and cameras to get the object buffer.

Thanks Adam
I tried that before but when I got it into After Effects the cameras seemed out of sync.
I was using a regular camera and animating it. Is the sync thing a C4D or AE issue do you think?The animation was also a bit jerky so now I’m going to try camera morph.
Cheers
Jake

Hmm, there should be no difference assuming you didn’t change the Cinema camera settings … and have the same frame rates.
