I'm rendering out a motion vectors pass in C4D R13 and the sky object renders out black ... which is a problem. I've turned off alpha and still not the right result. What am I doing wrong. Cinema is not calculating the sky.

if your compositing in After Effects you might need to change your image interpretation to ignore ... the sky might have a baked in alpha

hope this helps

The Sky object is no geometry, so you'd need to use a big sphere object instead
should you need the vector from it.

That is exactly what I ended up doing. Making a sphere at 100,000 radius. Re-rendering it out and putting a simple texture over everything. Pretty lame!
