Nuke Facial Replacement Techniques
This new video discussed several areas of Visual Effects in regards to doing facial / muzzle replacement techniques while in a compositing environment. We will show you how to stay in Nuke for the entire voyage of capturing the motion and turning it into a monstrous transformation.

Introduction
Start off by separating the talent from the green screen background, then key in sections of the head, body and core to preserve as much detail and data as possible. Utilizing the Nuke camera tracker begin the projection and mesh alignment stages before moving into painting and texturing the shot. Learn how to add in additional alterations such as grid and spline warp, muzzle flashes and displacements. The final result will be amazing and these techniques will transfer to many other projects.

Keying

Painting

Writing out a single frame of the faces texture gives the option to do some paint work on it. Utilizing Photoshop add a scarred or burned area to the face, by using very basic paint tools and layering images to use as textures on top.

Part IV: Texturing
Load the painted version back into Nuke and now the ability to re-texture the mesh is ready since it is already in the proper UV layout. Also load in an alpha of the paint work to define the area needed to use further down in the script.

Grid Warp
