z depth with globals is ickly. Mayas zdepth will render out to iff if you dont have a 32 bit format chosen. Main issues are that mayas z depth doesnt render out to a visible range so you have to multiply it into the visible range somtimes. Also its not anti=aliased, when maya renders z depth it just finds distance as an absolute. So to get around that you have to render z depth at double res and than scale it down with a filter, which is really not fun. Shader ftw. Ha ha! Solved it! I went with this approach.... https://studiof504.blogspot.com/2010/...th-preset.html Where you disconntect the old min and old max attributes and then changes those values. Using that method the batch redners were the same as the single image renders.
