This isn't too surprising. Your original deep data has discrete color samples for each deep sample in places where objects overlap, but your flattened color data has no "samples" to speak of. Thus, when you apply your DeepRecolor, Nuke has to basically take each pixel and spread its value out across all the deep samples at that pixel's coordinates with no knowledge of what the original sample colors would have been.
Also, keep in mind that deep data isn't a silver bullet for depth-based defocusing. It's important to remember that even deep images have blind spots (unless you use tricks like telling the renderer that every object is semi-transparent), so at a certain radius, your blur will start to break down around the edges of overlapping objects. I'm guessing your artifacts are the result of a combination of these two limitations. -Nathan On 2/9/2017 12:36 AM, Gabor L. Toth wrote: > Hi, > > we are testing peregrine's bokeh in our pipeline.
