Hi all!
I'm rendering out an environment for compositing with real life footage. My renders are going to a Nuke person.
The elements I've been rendering out don't seem to include a correct surface alpha. I might be missing something, possibly sleep or similar, but I am curious as to what's happening here. The tgSurfAlpha has values I expect to be 0 or 1 but which are 0.7 or similar. The depth is occluding the alpha and I really don't want that.
Surely the default elements can be combined to get an alpha where 0 is the sky and 1 is the ground...
I've done this before so it's driving me mad.
Alex
