04 Workspaces and how to customise it


Session 4 – Exploring Blender Workspaces

Intro
Welcome to Session 4! In this lesson, we’ll explore Blender’s Workspaces from the top menu bar and understand what each one is designed for.

1) Starting point: Layout

  • When you launch Blender, it opens in the Layout workspace by default.
  • I have chain_animation.blend open and I’m currently in Camera View.
  • Press Numpad 0 to toggle into Camera View, and press Numpad 0 again to toggle out of it.
  • In Layout, you’ll see four panels:
    1. Viewport (main working area)
    2. Outliner (top-right; shows your scene’s collections and objects)
    3. Properties (bottom-right; object and scene settings)
    4. Timeline (bottom; for playback and keyframes)

2) Modeling

  • Click Modeling on the top workspace bar.
  • Notice the mode automatically switches from Object Mode to Edit Mode.
  • Here you typically see three panels:
    • Viewport (center)
    • Outliner / Collections (right)
    • Properties (right, below the Outliner)

3) Sculpting

  • Go to Sculpting for organic forms like faces, creatures, and cloth.
  • The mode changes to Sculpt Mode.
  • You’ll again see three panels:
    • Viewport
    • Outliner
    • Properties

4) UV Editing

  • Open UV Editing to prepare meshes for texturing.
  • On the left, you have the Image Editor (to unwrap and view UVs).
  • On the right, you have the 3D Viewport (to select and unwrap geometry).
  • You still have Outliner and Properties on the right side as part of the standard layout.

5) Texture Paint

  • Switch to Texture Paint to paint directly on your model.
  • On the left, you’ll see the Paint/Image Editor.
  • On the right, you have the Viewport for painting on the 3D model.
  • Outliner and Properties remain available on the right.

6) Shading

  • Go to Shading to assign and build materials.
  • The Shader Editor sits at the bottom for node-based material setups.
  • On the left, you have a File Browser to quickly bring in textures.
  • An Image Viewer is available for inspecting images.
  • Outliner and Properties are on the right, as usual.
  • Shading is crucial—you’ll use it constantly for look-dev.

7) Animation

  • Open Animation to set up and polish motion.
  • You see two views:
    • A Camera View
    • A regular Viewport
  • At the bottom is the Timeline for keys and playback.
  • Outliner and Properties are on the right.

8) Rendering

  • Click Rendering to review output.
  • This workspace provides a render display so you can focus on final frames and results.

9) Compositing

  • Go to Compositing to combine and enhance rendered images—similar to After Effects.
  • You’ll layer and process images node-by-node.
  • We’ll dive deeper into compositing in a later session.

10) Geometry Nodes

  • Open Geometry Nodes for parametric modeling and procedural setups.
  • This is where you’ll build reusable, non-destructive tools for modeling and motion.
  • We’ll explore this in detail in future lessons.

11) Scripting

  • Finally, Scripting is where Blender’s Python integration shines.
  • You can write, open, and execute Python scripts directly inside Blender to automate tasks and build tools.
  • We’ll explore this later as well.

12) Adding more workspaces (+)

  • Click the “+” icon next to the workspace tabs to add preset layouts:
    • General (multiple options)
    • 2D Animation (four panels tuned for grease pencil)
    • Sculpting (two panels)
    • VFX (four panels for tracking and effects)
    • Video Editing (two panels for cutting and audio)
  • You can also duplicate the current workspace to create a custom version.

13) Start from Layout & fix the screencast-keys toggle

  1. Switch to the Layout workspace.
  2. You may notice the Screencast Keys overlay is missing.
  3. Press N to open the 3D Viewport Sidebar.
  4. Find Screencast Keys (add-on panel), turn it OFF, then turn it ON again.
  5. Press N to close the Sidebar. The overlay should now be visible.

Tip: This toggle is a known quirk; a quick off/on restores the overlay.

14) Duplicate Layout and name your workspace

  1. Click the “+” icon next to the workspace tabs.
  2. Choose Duplicate Current.
  3. Rename the new workspace to “Sathrit” (your custom workspace).

You’re now editing a safe copy without altering the original Layout.

15) Meet the “secret” Editor Type button

  1. In any panel, go to the top-left corner and click the Editor Type selector (the “secret button”).
  2. This menu lists ~23 editor types, grouped as:
    • General (9)
    • Animation (6)
    • Scripting (3)
    • Data (6)
  3. Try it: in the main window (currently a 3D Viewport), change it to File Browser.
    • The entire panel becomes a file browser you can use to navigate assets.

16) Add a new right-side panel (Vertical Split)

  1. Hover over the vertical border of the File Browser until the cursor becomes a double-arrow.
  2. Right-click → choose Vertical Split.
  3. Move the split line roughly to the center and click.
  4. In the right panel, set Editor Type → 3D Viewport.
    • Result: Left = File Browser, Right = 3D Viewport.

17) Add a bottom panel (Horizontal Split) and set it to UV Editor

  1. In the left (File Browser) panel, hover on its bottom border until you see the double-arrow.
  2. Right-click → Horizontal Split.
  3. Place the split where you want and click to create a new bottom-left panel.
  4. In that bottom-left panel, set Editor Type → UV Editor.
    • Result: Bottom-left = UV Editor, Top-left = File Browser, Right = 3D Viewport.
  5. You still have Outliner and Properties on the right side, and a Timeline across the bottom from the original Layout (if present in your theme).

18) Swap the Timeline for the Shader Editor (for look-dev)

  1. Click the Editor Type of the Timeline area (bottom).
  2. Change it to Shader Editor.
    • Result: You now have UV Editor, File Browser, 3D Viewport, Shader Editor, plus Outliner and Properties—a great modeling/look-dev layout.

19) Save your layout with the file

  1. Go to File → Save.
  2. This saves the current workspace layout with your .blend.
    • (Optional, future-proof): To reuse this layout every time, File → Defaults → Save Startup File.

20) Remove panels using “Join” (clean up quickly)

If you want to remove a panel and give its space to a neighbor:

Method A — Join via Right-Click

  1. Hover over the border between two panels → Right-click.
  2. Choose Join Down, Join Up, Join Left, or Join Right (as appropriate).
    • Example: Join Down removes the bottom panel and expands the top one.
    • Example: Join Left removes the left panel and expands the right one.

Method B — Corner Drag (crosshair/hairpin)

  1. Move to a panel corner until the cursor shows a crosshair/hairpin.
  2. Click-drag into a neighboring panel to split it, or drag out to collapse/join (depending on direction and Blender version).
  3. Release to confirm.

Try it now:

  • Join Down to remove the bottom UV Editor and expand the File Browser.
  • Join Left between File Browser and 3D Viewport to remove the File Browser and make a larger Viewport.
  • Similarly, you can join away Outliner and Properties if you want a pure viewport setup.

21) Challenge: Build a Four-Panel View (Top, Front, Right, Camera)

Goal: Only four panels across the entire screen, each a 3D Viewport.

  1. On the “Sathrit” workspace tab, right-click → Rename it to “Four Panels”.
  2. Remove any extra bottom panel (e.g., Shader Editor) using Join Down or by corner dragging to collapse it.
  3. Split vertically once to make left and right halves:
    • Hover border → Right-click → Vertical Split → click to confirm.
  4. Split horizontally on each half to make top and bottom rows:
    • Hover border → Right-click → Horizontal Split → confirm.
    • You should now have a 2×2 grid (four panels).
  5. Ensure all four panels are 3D Viewports (use the Editor Type button if needed).
  6. Set views using the Numpad:
    • Top-Left: Numpad 7 = Top view
    • Top-Right: Numpad 1 = Front view
    • Bottom-Left: Numpad 3 = Right view
    • Bottom-Right: Numpad 0 = Camera view
  7. (Optional) Press 5 in each panel for Orthographic (if you prefer ortho for Top/Front/Right).
  8. File → Save to store this four-view layout with your project.

Pause here and try it yourself before moving on. Getting comfortable with split/join and view assignments will speed up your workflow massively.

22) Recap & What’s Next

  • You learned how to duplicate workspaces, toggle Screencast Keys, switch editor types, split/join panels, and save custom layouts with your file.
  • Next session, we’ll focus on the 3D Viewport—navigation, view controls, shading modes, overlays, and selection essentials—so you can model and animate efficiently

05 The Language of Film: Cuts, Moves, and Meaning


Briefing: The Birth of the Feature Film

Dr Sudheendra S G reviews the key themes and facts presented in the provided source, "The Birth of the Feature Film: From One-Reel Wonders to World-Building." It outlines the evolution of cinema from short novelty clips to the sophisticated narrative structures of feature films, highlighting the parallel developments and distinct contributions of Indian cinema.

Main Themes and Key Ideas:

  1. The Evolution from Novelty to Narrative: Early films were short, often "50-second clip[s]" demonstrating simple actions like "trains arriving, workers leaving, magic tricks." The transition to feature films was driven by an audience desire for "long stories" and a corresponding industry maturation.
  2. Standardisation of the Film Industry Pipeline: As cinema grew, a "recognizable pipeline formed" comprising:
  • Studio: "makes the movie (stages, props, editing rooms)."
  • Distributor: "markets & books the movie into theaters."
  • Exhibitor: "shows it (theater chains, and today, streamers)." In the early 1900s US, "many companies were vertically integrated," controlling all three stages. While this offered "Great for control," it was "terrible for competition," eventually leading to court-mandated breakups.
  • India Connect: Companies like Madan Theatres (Calcutta) built "powerful production–distribution–exhibition networks" in the 1910s–30s, demonstrating that "The pipeline mattered as much as the pictures."
  1. Patent Wars and the Rise of Hollywood: In the US, "Thomas Edison claimed patents across cameras and projectors," leading to "Patent Wars." This resulted in the formation of the MPPC ("the Trust"), a "de-facto monopoly that controlled who could shoot, what could screen, and even access to raw film stock." Independent filmmakers "rebelled, ran far from New Jersey, and found sunlight + landscapes in… Hollywood." This exodus, combined with legal challenges, "cracked the monopoly and opened space for longer, riskier films."
  • India Connect: While there was "No single ‘Trust’," the control over "stock, venues, and circuits similarly determined who got seen," establishing distribution as "the hidden boss of Indian cinema."
  1. The "Length Revolution" – From One-Reelers to Features: Monopoly rules initially "capped films at one reel (10–16 min)." However, "Audiences wanted more," and the success of "multi-reel imports" like European spectacles (e.g., The Loves of Queen Elizabeth (1912) and Quo Vadis (1913)) proved the commercial viability of longer films. "The market began to accept features as the main event."
  • India Connect: "Dadasaheb Phalke’s Raja Harishchandra (1913) is India’s first full-length feature," designed for "sustained attention" with its mythic narrative. By 1931, "Ardeshir Irani’s Alam Ara turned the ‘feature’ into the talkie feature, re-wiring audience expectations with songs, dialogue, and star performance."
  1. D. W. Griffith: Technical Innovation and Moral Contradiction: D. W. Griffith is credited with significantly shaping "how films speak" through techniques such as:
  • "Close-ups for emotional emphasis (faces as story)."
  • "Insert shots (hands/objects) for symbolic beats."
  • "Flashbacks to layer time and character."
  • "Cross-cutting to braid simultaneous actions into suspense." These innovations "made films feel modern—not just moving pictures, but moving people." His blockbuster The Birth of a Nation (1915) demonstrated the box office power of features but was marred by its "violently racist ideology that glorified the KKK." The source stresses that "The film’s technical brilliance and moral bankruptcy are inseparable in film history," leading to protests and the emergence of "counter-cinemas" like Oscar Micheaux’s Within Our Gates (1920).
  • India Connect: Indian filmmakers "adopt the toolkit, not the worldview." Figures like "V. Shantaram, Bimal Roy, Guru Dutt refine close-ups, inserts, and cross-cutting to sculpt melodrama, social critique, and musical rhythm." Crucially, "The song sequence becomes an Indian invention of narrative elasticity—a feature-length story interwoven with lyrical time."
  1. Why the Feature Film Became the Default: The feature film "stuck" once "industry logistics + audience appetite + visual grammar clicked." It offered benefits across the board:
  • "Industry could market a main event."
  • "Theaters could program around a headliner."
  • "Filmmakers could arc characters across acts."
  • "Audiences could invest emotionally over ~2 hours."
  • India Connect: The combination of "Feature length + music birthed the Masala grammar—action, romance, comedy, social stakes in one container," enabling Indian cinema to "scale myth + modernity for the big tent."

Conclusion:

The feature film was not merely a longer movie; its emergence was a complex interplay of industrial professionalisation, technological innovation, the development of a sophisticated "visual grammar," and evolving audience demands for "arcs, stakes, and catharsis." While D. W. Griffith globalised many of the foundational craft elements, he also exposed "cinema’s ethical stakes." In India, pioneers like Phalke, Irani, and Shantaram adapted these tools to create a "distinctly Indian feature language—songs, stars, spectacle, and social feeling," demonstrating the global and localised power of long-form storytelling.

04 Georges Méliès: Master of Cinematic Illusion


🎬

The Language of Film: Cuts, Moves, and Meaning

Dr Sudheendra S G explores the evolution of film as a language, tracing how early filmmakers, particularly Edwin S. Porter, established foundational cinematic techniques.

 

 It details the development of cuts, camera movements like pans and tilts, and varied shot sizes as crucial elements for storytelling and conveying meaning.

 

The text also highlights India's significant adaptation and expansion of these techniques, showcasing how Indian filmmakers have integrated and innovated upon these grammatical rules within their unique cultural and narrative contexts.

 

Ultimately, it demonstrates how these standardised building blocks allow for diverse cinematic expression across different genres and regions
