Final Project Entry 2 : Nuke Workflow

-
The first step was to setup relative paths and to organize everything into appropriate folders. Once I bring in the footage I convert it into an image sequence and apply a primary color grade and correction. Then I imported the 35mm lens distortion grid and ran the grid detection function using the lens Distortion node. Some manual correction was required to detect every point on the grid once that was done the STmap was exported and attached it to the footage.
Raw Footage

Primary Grading

Color Correction
The lens distortion caused the bounding box to be expanded by 10 pixels on both axes, which was factored into the reformat node and the undistored footage was exported.



Next was to match move and 3d track the footage. This footage was fairly clean there were no issues as the footage only has 2 planes the ground and the wall behind, there are buildings and trees beyond the wall but they get cut as the camera closes into the wall section. So for the majority of the shot its just tracking 2 perpendicular surfaces. Initially the error rate was around 0.9 but a few tweaks to the min length and max error, enabling position and rotation bought it down to 0.74. After establishing the ground plane and setting the scale in cm. The scene was exported out using the WriteGeo node.

Entry 7: Intro to Maya Render Layers and AOVs

-
Image
 As a 3D Artist I was familiar with the modelling and texturing side of Maya, but I was never exposed to the VFX side of it until now. This week we looked into how to add textures to our assets and how to use the node graphs for the same. Once that is set we learnt about render layers, overriding textures and AOVs. All of the assets in the scene will have aiStandardSurface and the surfaces that receive shadows and reflections will have aiShadowmatte as their materials.  Tips for Materials : 1. Always set color space as RAW for everything except base color. 2. Enable "Alpha is luminance" for everything except base color and normal map. 3. If you have a very shiny CG asset in the scene, add real textures from the footage to the ground and wall planes for the asset to pick up and reflect them as this would help it blend  with the scene. What are Render Layers and why do we use them? Render Layers allows us to separate each element of the render into their own exr image,...

   Colour Correction, Grading and Colour Theory This week’s class was focused on understanding colour properties and how to grade and correct colour in Nuke. One of the key things here is to match the black and white levels of all the elements, the darkest and lightest points of the footage and the corresponding points of the CG and foreground elements should be the same. This can be achieved using the Grade node with which we can set the black and white levels to match. Different levels of correction – Primary Colour correction aims to correct colour at the highest level, it affects the entire final output. Secondary correction is applied to specific elements individually to make them tonally consistent with the rest of the footage. Colour correction is an essential process to make sure all the elements we add match the footage, whereas colour grading is a more artistic choice that aims to bring about a tone to the full final image output, so this layer is added o...
