This blend file contains the working node group used by Theory Animation Studios for animation rendering in Cycles. We recommend using minimum 100 samples for the best minimum quality, but it also can be tuned in to get good results around the 500 sample range depending on your scene file.
This technique was outlined in a video tutorial by Bartek Skorupa on www.cgcookie.com, but was further refined for our uses with trial and error.
in your new scene file, append from this file in node tree>noise cancellation, and then in the compositor add group and choose noise cancellation node group.
In your render layers tab under passes, enable all diffuse, glossy and transmission as well as emit and environment, and also Z and Normal. Check 'use nodes' in the compositor, and then disconnect the image socket from the composite and add the viewer and the composite node to the output of the noise cancellation group node. Link up the corresponding passes in your render layer to the node sockets in the noise cancellation group, and then set your samples to at least 100 before rendering with Cycles.
Incidentally, if any of that doesn't sound right, compare your new file to the existing scene I set up with this one.
Thanks for your share , but im a noob , any suggestions on how to use it on another scene ?
