Welcome to part one of Visual Effects Core Skills
Nearly 6½ hours of material which covers the key essentials of 3D, compositing and visual effects.
This first of a two part series covers the key concepts and theories underlying Visual Effects that are often missed or misunderstood by both the new and experienced artist. These foundational concepts are common to whatever software you use. For these videos we’ve focused on using Maya, Mental Ray and Nuke to demonstrate these principles, however we touch on many other tools along the way.
During the 6½ hours of material you’ll cover :
(For a more detailed overview of each video see ‘Full Breakdown’ below.)
spherevfx would like to thank:
along with Autodesk, Nvidia, Pixar’s RenderMan Team, Chaos Group, Solid Angle and The Foundry.
2D and 3D file formats, bit depths, file format encoding, colour depths, and layers and channels. Also common misunderstandings with naming conventions and file format pipeline.
Transform concatenation, Nuke nodes that concatenate, concatenation and filtering, and colour concatenation.
Filter algorithms, Nuke nodes that apply filtering, filter types and usage.
Pre-multiplied images, the maths behind premult / unpremult, when to use premult / unpremult with colour correction and multipass, and output settings from 3D renderers and 2D applications.
Matrices, understanding the grid, examples including: transform, blur, sharpen, edge detection and emboss.
Expressions – colour, transform, merge, creation and random number based expressions. We also look at working with variables and custom attributes.
Introduction to multipass rendering and compositing, overview and types of multipass.
Multipass – Object passes, Maya render layers, layer overrides, hold out matte creation, and rebuilding the ‘beauty’ in Nuke.
Multipass – Lighting passes, Maya render layers, rebuilding the ‘beauty’ in Nuke, adjusting light colour and intensity in Nuke.
Multipass – Shader passes, Maya render layers, Global Illumination, 47 Mental Ray render passes explained, understanding openEXR 2.0, correct rebuild of the ‘beauty’ in Nuke, good and bad compositing practices, understanding Nuke’s Layer and Channel system (including Add, Shuffle, ShuffleCopy, and Copy), methods of multipass compositing (including ‘shuffle’, ‘in-the-pipe’, ‘adjustment-only’. Also we look at passes from Arnold, RenderMan and V-Ray.
Multipass – AOV passes, setting up multiple Arbitrary Output Variables including Z-Depth, Motion Vector, UV’s, Normals, Position and Matte passes, and building custom passes within Maya. Adding depth of field and depth cueing via Z-Depth, using mattes for colour corrects and effects, retexturing using UV’s, building point clouds using the Position pass plus 2½D relighting using Normals, and finally applying motion blur using Motion Vectors.
Working with cropped sensor cameras, conversion maths from full frame sensor (35mm) to any cropped sensor.
Overscan Rendering for Lens Distortion, un-distorting plates, calculating additional BBox size, adding Overscan to camera in Maya, calculating extra render resolution, resizing renders and applying lens distortion in Nuke.
