Introduction to VFX & CGI

Video Effects (VFX)

  • All about combining our Computer Generated Imagery (CGI) with real world environments.
  • This can be models, particle effects etc.
  • We will start with a still image and place a model into it.
  • After we have mastered that we will conquer video footage!

Choosing Your Subject

  • You can follow along with me, choose your own path or both!
  • Keep it simple, this goes for both your model AND the “real” space it is going to occupy.

Good Source Material

  • Picture/photo, video or even another render
  • We’ll grab a photo and check out it’s settings.
  • This is important with both stills and videos.
  • With you own video keep a note of the settings as they’re often lost

Introduction to Compositing

  • Bringing different renders together into one final render.
  • Compositing is done in the Node Editor.
  • View your composite changes live.
  • Learn how to scale a background image independently of the final render resolution.

Matching Camera Settings

  • We will setup the camera using the settings gathered from the picture.
  • Reiterate the importance of accurate camera data.
  • Use the Text Editor to store data for reference.
  • Start setting up a scene to match the photo.

Mathematics And Images

  • Can be difficult to comprehend at first.
  • Initially focus on monochrome (Grayscale).
  • Reminder that Colour is generated through 3 channels, Red, Green and Blue, with values from 0-1 (Sliders show 0-255).
  • Each Pixel will have its own values.
  • Use one value for all Pixels

Basic Mathematics

  • Adding, subtracting, dividing and multiplying are just as you would expect them to be.
  • Values that are less than 0 or greater than 1 are passed through unless clamped.
  • Colour>Mix and Convertor>Math nodes function almost the same, however there are different options.

Overlaying Images

  • Background Image - Visible
  • Our Object - Visible
  • Our Objects Shadow- Visible
  • Ground - Used for capturing the shadow -Hidden
  • How we can isolate the object by itself.
  • How we can isolate the shadow by itself.

Extracting Image Data

  • We could take the background image and map it to an object that is visible in our render.
  • We have all the 3D data to make a comparison scene.
  • Create another Render Layer for comparison without the object and therefore no shadow.
  • Need to consider the order of these layers.

Blender Camera Tracking: Footage

Blender Camera Tracking: Markers

  • Markers track parts of the footage.
  • Uses similar controls to the 3D Editor
  • You’ll need a minimum of 8 in the scene to effectively track a camera, more the better.
  • Well have a look at Pattern Size and Search size, discovering what they do.
  • Recommend placing markers manually.

Solving Camera Motion

  • You need the right camera details!
  • Check the accuracy of our markers
  • Average camera solve error of <1 is ideal, but not always necessary. We have to test and assess.
  • May have to refine your markers more.

12 CGI / VFX Final Scene

  • Import assets you wish to use in your scene.
  • Adjust your camera's view, if it is slightly out.
  • Get the ground ready for shadows.
  • (Updated 9/6/2018)

Transparent Backgrounds

  • Learn how to set your Background as transparent.
  • The options are different in both Blender Render and Cycles.
  • Relatively straightforward - however the options are hidden away!
