Scott from Impossible Engine shares a short video showing a workflow for using Cinema 4D with V-ray to create multi pass EXR files for compositing in Nuke. Check out the post for VrayforC4D Multipass workflow for Nuke tutorial here.
Scott notes that when the Impossible Engine Studio were using V-ray and Cinema 4D on a recent project (being a Nuke shop), there seemed to be very little resources available on how to create render and tech passes as EXR files. Scott takes a look at some important issues that you may encounter when rendering compositing passes such as color mapping, as well as how everything comes together in Nuke.
…There may be a better way to do this but we could not find any video tutorials specific to this workflow and thought we’d throw something together to help get anyone stuck at least started…
VRAYforC4D is a product created by LAUBlab KG Vienna who licenses V-Ray from the Chaos Group and adds their Cinema 4D integration (V-Ray Bridge) to it and then retails VRAYforC4D for around $980.00 US for c4d 11-5 to c4d 13.0. When you purchase VRAYforC4D you also receive support from LAUBlab as well as the Chaos Group as you have in essence purchased a standard license of V-Ray.
