there are times when you have use for deep without having multiple values per pixel
for example: *you have a single object rendered out that you wanna comp into a deep comp. *you just want to use as 3d space reference by converting it to points so you can position cards etc G On Mon, May 20, 2013 at 9:26 AM, cbmiles <[email protected]>wrote: > ** > I recently watched a video on youtube stating that you could create deep > data from Z-Depth. > > http://www.youtube.com/watch?v=59fnQW_KUOU > > His approach was to copy rgba.red to depth.z and then attach a > DeepFromImage node. > > Z-Depth is determined by the brightness value per pixel given from the 3D > render.
