Week - 8 Arnold Rendering Techniques, Render Layers

-
This week we focused on Rendering and Lighting in Maya Workflow we did this by looking at the workshop tutorials on canvas.

The first tutorial was about Light Groups - You can create lights and organize them into groups in the Light Editor. This way, you can adjust multiple lights simultaneously, and your Light Editor interface appears more streamlined and organized.
If a group is currently selected in the Light Editor, the newly created light is automatically added to this group. Otherwise, the light is created but does not belong to any group. You can also create a light within a group by right-clicking the group and selecting the light you want from the marking menu.To group lights Click New Group to create a group, and middle-drag and drop lights to include or exclude them from a group.Each light can only belong to one group.Note: All lights created via the Maya Create menu appear in the Light Editor, but do not automatically belong to any group.
Once this is rendered we can import them to Nuke and by using the shuffle nodes we can be able to different passes and use them independently.
The second tutorial was about Motion Blur - Motion blur can enhance the realism of a rendered animation by simulating the way a real-world camera works. A camera has a shutter speed, and if significant movement occurs during the time the shutter is open, the image on film is blurred. We just store the motion blur data in  AOV's and then they can be tweaked in Nuke one of the advantages of doing this to speed up the rendering process.
To do this we go into render settings in Maya, click on motion blur and click enable and select instantaneous shutter by making this we can create motion blur which doesn't show when rendered but can create an  AOV then export them to Nuke where we can use the VectorBlur node to create MotionBlur.

In the same tutorial we get to know about Depth of Field - Depth of Field to create a blur that is applied to out-of-focus points of light to simulate a shallow focus. We can add a Z pass in our AOV in our render settings. This will store the depth of field information we need in our multi-layered image, so in Nuke we can use a ZDefocus node - Blurs the image according to a depth map channel. This allows you to simulate depth-of-field (DOF) blurring.

Even after looking at the tutorials provided in canvas, I had trouble understanding how AOV's work but after seeing some tutorials from YouTube I now have a basic understanding of how AOV's work.
Final Project Update
Was looking at videos on people walking while heavily drunk and got an idea on how to incorporate them in my project

Final_Project

For my final project I was thinking of making a character wake up from a blackout and walk away from the scene. I downloaded the model and animation from mixamo and used Garage_Footage Video 4 as my footage. Phase - 1: Imported the video to nuke and used write node to get the image sequence Phase - 2: Making the image sequence to Undistorted image, by creating a STMap Phase - 3: After making the STMap for my footage, using write node got the undistorted image sequence. Phase - 4: Camera_Tracking, after tracking the image sequence, solving it and using auto tracks to make the error rate of the tracks less than 1, I then created the scene, set ground planes, used the measurements given to us to scale to real world size, after that used the WriteGeo node to export .exr file to import it to Maya.  Maya Workflow: Set the Project Window and imported the scene into Maya, imported the image plane sequence and brought in my character from mixamo, at first I tried to add just the animations ...

Week - 4 3D Workspace in Nuke

-
Image
This week we will be focusing on working in 2D and 3D space, 3D projection and Matte Painting. First I brought in a Jpeg of a subway and linked it to the viewer and pressed Tab so that it switches to 3D view. Add a 3d object in this case we are using cube as the 3D object for the texture of the cube I added a Checkerboard node and connected the img to the Checkerboard node. When we come back to 2D space we can see that the cube does not show up in order for it to be seen we use ScalineRender node -  When connected to a Scene  node, the ScanlineRender node renders all the objects and lights connected to that scene from the perspective of the Camera  connected to the C am  input. Connect Cam input to Camera node, the Bg input to Footage and the obj/scn to the scene. Now connecting the scanlinerender to the viewer now we can see the cube. Now c reate a card (geometry) node in the node graph and connect the card node into the scene. Add a grid node to the Card now the c...

Week - 3 2D Tracking: Tracker, Planar Tracker, Rotopaint, Match-moving

-
Image
For this week we were focusing on covering on topics such as tracker, planar tracker, rotopaint and match-moving. In the morning session we did several colour matching exercises using a reference shot and a match shot, added a grade node and used the blackpoint, whitepoint, lift and gain to colour match one image to another (the reference). The image that has the grade node we should use Ctrl+Alt+Shift and select the blackpoint and whitepoint in the colourgrade node. Lift and gain using the other image just Ctrl+Shift.  One important distinction we learnt was to also use the alt key when colour picking from the image that has the grade node attached to it, which basically tells the software to ignore the alterations made by the grade node and to colour pick from the original ungraded image.   I then inserted another footage a diner match and a diner reference file and following a similar process I inserted a grade node beneath the match and reference files, I then linked...
