Week - 9 Motion Blur and Depth of Field

-
This week we learned how to implement Motion Blur and Depth of Field to a model in depth.

The morning session Richard let us work on our Blogs and go through tutorials if needed. After catching up with my Weekly Blog, I strated thinking on how to move on with starting my Final Projects, started seeing the criteras for our assignments and made a note on them.

First we bring the model to Maya and the model has an animation where it is electrocuted. After that Richard started teaching on how to use File Path Editor to place textures.Advantage of using this is it saves time when we have a lot of textures to place.

Set the directory where the texture folder is stored once done click set,

If the process is done correctly, the model will be textured and all path will be in green colour.

In order to undestand the textures that are applied to the model we can see them in node system which is same as in Nuke.

This is how the textures applied are seen in node system.
Now we add Ambient Occlusion so that we can give the texutres soft shadows to make them realistic, by using MultiplyDivide node - This utilitly multiplies or divides input attributes. We use the ouput of 2 channels, Albedo and AO as the 2 inputs to MultiplyDivide node then the output is given as Base Colour in MainNode.

Now we apply MotionBlur to the model by creating a custom AOV, then I dragged the aiMotionVector from create menu in Hypershade to the new custom aov. I enabled the Encode Raw Vector node so it will take uncompressed raw data, now the model has motion blur as it takes time to render in maya we disabled InstantaneousShutter. This can be imported and motion blur can be added in Nuke by using VectorBlur node.

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

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...
