Blender Crash Course
The Complete Workflow Reference
1. Interface Overview
Blender's interface is divided into editors — each area of the screen can be set to any editor type. Understanding which editor you need is the first skill to master.
3D Viewport
Where you see, select, and manipulate 3D objects. The main working area.
Properties Panel
Object settings, materials, modifiers, physics, and render settings.
Outliner
Scene hierarchy — lists every object, collection, and asset in your file.
Timeline / Dope Sheet
Animation keyframe management and playback controls.
Shader Editor
Node-based material and shader creation.
Graph Editor
Fine-tune animation curves and interpolation for smooth motion.
Tip
Hover over any area and press Ctrl Space to maximise it. Press again to restore the layout.
2. Navigation & Essential Shortcuts
Blender relies heavily on keyboard shortcuts and the middle mouse button. Learning these first saves enormous time.
| Action | Shortcut | Note |
|---|---|---|
| Orbit view | MMB drag | Middle Mouse Button |
| Pan view | Shift MMB | |
| Zoom | Scroll | Or pinch on trackpad |
| Numpad views | 1 3 7 | Front / Right / Top |
| Camera view | 0 | Numpad 0 |
| Select object | LMB | Left click |
| Select all / none | A | Toggle all selection |
| Box select | B | Drag to select region |
| Delete | X | Prompts confirmation |
| Add object | Shift A | Add menu |
| Toggle Edit Mode | Tab | Object ↔ Edit |
| Search commands | F3 | Find any operator |
No Numpad?
Enable Emulate Numpad in Preferences → Input to use the number row at the top of your keyboard for view shortcuts.
3. 3D Modeling
Blender uses a mesh-based modeling system. Every 3D object is made of vertices (points), edges (lines), and faces (polygons). In Edit Mode you manipulate these directly.
| Action | Shortcut |
|---|---|
| Select vertices / edges / faces | 1 / 2 / 3 |
| Extrude | E |
| Loop cut | Ctrl R |
| Bevel | Ctrl B |
| Inset faces | I |
| Merge vertices | M |
| Knife tool | K |
| Proportional editing | O |
| Grab / Move | G then X Y Z to constrain axis |
| Scale | S |
| Rotate | R |
Modifier Workflow
Use the Subdivision Surface modifier to add smoothness non-destructively. Apply the Mirror modifier to model only half of a symmetrical object. Modifiers appear in the Properties panel under the wrench icon.
4. Materials & Shaders
Materials control how a surface interacts with light. Blender uses a node-based shader system — the Principled BSDF node covers most real-world materials.
Principled BSDF Key Inputs
Texture Workflow
- 1. UV Unwrap your mesh (U in Edit Mode)
- 2. Open Shader Editor
- 3. Add Image Texture node (Shift A)
- 4. Load your texture image
- 5. Connect Color output → Base Color
HDRI Tip
For realistic lighting, use an HDRI environment texture. Go to World Properties → Surface → Environment Texture and load a .hdr file from Poly Haven (free, CC0 licensed).
5. Rigging
Rigging creates a skeleton (armature) that deforms your mesh. This is how characters move in animations.
Add an Armature
Shift A → Armature. This adds a single bone. In Edit Mode, extrude bones to build the skeleton.
Parent mesh to armature
Select mesh → then armature (Shift+click) → Ctrl P → With Automatic Weights.
Weight Paint
Switch to Weight Paint mode to control how strongly each bone influences each vertex. Blue = no influence, Red = full influence.
Pose Mode
Switch armature to Pose Mode (Ctrl Tab) to rotate bones and test deformation.
6. Keyframe Animation
Animation in Blender works by recording the value of a property at specific frames. Blender interpolates between keyframes automatically.
| Action | Shortcut |
|---|---|
| Insert keyframe | I in viewport |
| Delete keyframe | Alt I |
| Play / Pause | Space |
| Go to frame | Type frame number in timeline |
| Next / Prev keyframe | ↑ / ↓ |
| Copy pose | Ctrl C in Pose Mode |
| Paste flipped pose | Ctrl Shift V |
Graph Editor
Open the Graph Editor to adjust interpolation curves. Select keyframes and press T to change easing (Bezier, Linear, Constant). Smooth Bezier curves give natural motion.
7. Lighting
Good lighting transforms a scene. Blender offers four main light types and HDRI world lighting.
☀ Sun
Parallel directional light — simulates sunlight. Rotation controls direction, not position.
💡 Point
Radiates light in all directions from a single point — like a light bulb.
🔦 Spot
Cone-shaped directional light — for focused beams and stage lighting effects.
⬛ Area
Rectangular soft light — closest to real studio lights. Best for product shots and portraits.
Three-Point Lighting
The classic setup: Key light (main, bright) + Fill light (soft, opposite side, dim) + Rim/Back light (behind subject to separate from background). Works for characters, products, and objects.
8. Rendering & Export
Rendering converts your 3D scene into a flat image or video. Blender has two main render engines with different strengths.
EEVEE (Real-time)
Fast, GPU-based. Renders in seconds. Good for game assets, motion graphics, and when iteration speed matters. Fewer accurate reflections than Cycles.
Cycles (Path Tracing)
Physically accurate. Slower but photorealistic. Best for final renders, films, and product visualisations. Supports GPU acceleration.
| Action | How |
|---|---|
| Render still image | F12 |
| Render animation | Ctrl F12 |
| Set output format | Properties → Output → File Format |
| Set output path | Properties → Output → Output directory |
| Save render | F3 in Image Editor |
Export for Game Engines
When exporting to Unity or Unreal, use FBX format and apply all modifiers before export. Set Forward = -Z and Up = Y to match most game engine coordinate systems.
