UV Texturing | 30/10

  • UV texturing in Maya is a process that involves assigning 2D coordinates (UV coordinates) to the vertices of a 3D model, allowing us to apply 2D textures accurately onto the model’s surface. This process is essential for creating detailed and realistic textures in CG and Animation.
  • Today we will see how texturing in a sphere works for example: Earth and other spherical objects.
  • For texturing spherical surface It’s better to use spherical projection texture.
  • To create texture for building, we should first unwrap the UV and modify the UVs to match with the proportions of the building.
  • We would take UV snap shot and import the image to Photoshop and Implement the textures using the UV snapshot as template.
  • After that we will export the matched texture back to maya and apply it in a material.

Rotoscoping in Nuke 17/10

  • Rotoscoping in Nuke involves tracing or isolating specific objects or elements in a video frame by frame. This technique is commonly used in visual effects to separate foreground elements from the background.
  • Import Footage:
    • Open Nuke and create a new project.
    • Import the footage you want to rotoscope by using the ‘Read’ node.
  • Create a Roto Node:
    • Right-click in the Node Graph and select “Draw” > “Roto.”
    • the Roto node to the footage node.
  • Rotoscope the First Frame:
    • Go to the first frame of your footage.
    • Use the Roto node to draw a shape around the object you want to rotoscope.
    • Make sure the shape encloses the entire object you want to isolate.
  • Keyframes:
    • Move a few frames forward in the timeline.
    • Adjust the shape of the Roto node to match the object’s movement.
    • Press ‘A’ on your keyboard to set a keyframe for the current frame.

  • Refine the Rotoscope:
    • Continue moving forward frame by frame, adjusting the shape of the Roto node as needed.
    • Use the handles on the Roto shape to modify its contours.
    • Set keyframes at regular intervals to ensure accurate tracking.
  • Feathering and Edge Blur:
    • To create a smoother transition between the roto shape and the background, use the “Feather” control in the Roto node.
    • Adjust the feather settings to control the softness of the roto edge.
  • Track the Rotoscope:
    • In Nuke, you can use the built-in tracker to automate the tracking process. Select the Roto node, go to the “Tracker” tab, and enable it.
    • Adjust tracking settings, such as search area and correlation, to achieve accurate tracking.
    • Fine-tune the results by manually adjusting keyframes if necessary.
Tracking to assist roto
  • Review and Adjust:
    • Play through the sequence to review your rotoscoping work.
    • Make any necessary adjustments to the Roto node or keyframes.
  • Output:
    • Connect the Roto node to the desired downstream nodes for further compositing.
    • You can use the roto shape as a mask for other nodes or apply color correction, effects, etc.
  • Render:
    • Once satisfied with the rotoscoping, render the final result.
