When doing a render, what would be the correct way to save the Z information to a file so i can restore it later? I would like to do a render of a scene and separally with lower settings a render of a smoke simulation and then load both images & their respective Z values and in the compositor unite them with Zcombine.
Thank you!
Connect z depth output to a File / Output node to save as an image in the format you specify, or send to Output node and save from the render window. OpenEXR file will save image depth data in the file or use MultilayerEXR to save all layers and passes in a single file
You can use File Input node to load external images/movies
thank you so very much!
Unfortunately, smoke and volume don’t have Z. So, you can do that for everything, except for what you’re asking.
