Digital Tutors – Advanced Compositing Workflows with Maya and Fusion (278mb) (rmvb)
English | Size: 268 MB
Category: Tutorial
In this series of lessons, we will be taking you through the process of rendering your Maya scene into multiple passes, and using some advanced techniques for compositing these passes using Fusion.
We will dedicate the first portion of this course to using Render Passes in Maya to separate various elements of our scene at render time. We’ll use mental ray’s render passes, contribution maps, custom framebuffers, and render layers to create the necessary render passes for our scene. In the second portion of this course we will begin with some quick compositing similar to our Compositing 3D Renders in Fusion course, but we will quickly get into more advanced topics such as basic and advanced Depth-of-Field techniques, working with HDR data, painting fixes and chromatic aberration.
Lesson Outline:
Introduction and Project Overview
In this lesson we will discuss the project overview for Advanced Compositing Workflows with Maya and Fusion.
Preparing Maya scene for multi-pass rendering
In this lesson we will look at the provided Maya scene and discuss critical factors to consider when attempting to render your scene into multiple passes.
Creating Contribution Maps for multi-pass rendering
In this lesson we will learn how to set up contribution maps in order to separate the various elements of our scene into rendered passes.
Setting up render passes in mental ray
In this lesson we will create a number of render passes and associate them to our Contribution Maps.
Using Custom Color Buffers to render specialized passes
In this lesson we will use Custom Color Buffers to render our subsurface scattering effects into separate Front Scatter, Back Scatter, and Diffuse passes.
Creating new Render Layers and using Layer Overrides
In this lesson we will create additional Render Layers and use Layer Overrides to change attributes on a per-layer basis, as well as rendering our various passes as HDR images for compositing in Fusion.
Setting up our Frame Format and LUT to see HDR colors
In this lesson we will learn how to bring in all our images, and set-up a gamma adjust LookUpTable to view the images in visible color space.
Using Merges to composite 3D Render Passes
In this lesson we will learn how to import our render passes and use Merge tools and Apply Modes to combine them.
Color Correcting and Tweaking our Ant using various tools
In this lesson we will learn how to make various changes to our passes, such as making our specular highlights brighter and removing them from the face with a Bspline Mask and Matte Control tool.
Creating a Lightwrap to tie the Foreground to the Background
In this lesson we will learn how to use our matte pass to create the lightwrap effect, which takes the actual background pixels and wraps them around the foreground. This effect goes a long way to creating a believable scene.
Fixing common HDR issues by Clipping the Matte’s White
In this lesson we will learn how to trouble-shoot some issues we’re having with our comp by searching for the culprit and fixing it with a Bightness/Contrast set to clip ultra-white values.
Painting our Alpha Channel to fix issues
In this lesson we will learn how to use the Paint node to remove part of our alpha channel where no color information exists
Setting up a Basic Depth-of-Field effect using the Depth pass
In this lesson we will learn how to use the Deep Pixel Depth Blur tool to blur the back of our and but keep the head in focus
Adding Depth-of-Field to the background
In this lesson we will learn how to copy our foreground tools to add the depth-of-field to our leaf background
Expanding the Depth Pass to fix Haloing
In this lesson we will learn how to fix the blurring and haloing effect around our in-focus areas by extending our depth pass to fill in all the black areas.
Expanding the Depth Pass of the Background
In this lesson we will learn how to apply the same fix we did to the foreground element to the background element.
Adding a VariBlur to fix the Ant Outline
In this lesson we will learn how to use the VariBlur tool along with the Brightness/Contrast and Channel Boolean tools to blur out the ant outline.
Adding Chromatic Aberration to our image
In this lesson we will learn how to add a photographic effect by changing our color channels.
Adding and Tweaking Grain for that final level of detail
In this lesson we will learn how to use the Grain tool to add random noise to our image and how to render a correct image out of Fusion.
Blurring the Depth Pass to fix tiny interpolation issues
In this lesson we will learn how to fix hard blur edges by adding a small blur to our depth pass.
