Blender Guru — Beginner Donut Tutorial Part 1 (2026)

Why this is in the vault

Filed because the blender-character skill (Ray-the-mascot pipeline) needs the execute_blender_code operator surface area memorized — Andrew Price’s hotkey-first vocabulary maps directly to the bpy ops we generate via MCP. Specifically: the modifier-stack non-destructive philosophy (solidify + subsurf, “start chunky and let the stack smooth”) is the exact pattern the Ray-mascot blockout phase needs, and the inset-to-fix-engons rule is the kind of thing the LLM will silently get wrong without a baked-in heuristic. Pairs with 2026-04-29-polygon-runway-2026-blender5-beginner (alternate teacher, same primitives) to give the skill two reference vocabularies.

TL;DR

Andrew Price’s fifth iteration of the gold-standard Blender intro, rebuilt for Blender 5.0. Part 1 covers: viewport navigation (orbit/pan/zoom), the add-mesh primitive workflow, the non-destructive modifier stack (solidify + subsurf), edit-mode geometry (vertices/edges/faces, loop cuts, insets), and the keyboard-shortcut-first philosophy that defines competent Blender work. The donut + coffee mug exercise is the on-ramp; the deeper lesson is “modifiers are non-destructive — start chunky and let the stack smooth it.”

Mapping against Ray Data Co — what I learned that helps me model Ray in Blender

The load-bearing extraction. Concrete techniques + hotkeys + patterns usable in MCP-driven Blender code generation:

Hotkeys (commit these to muscle memory for execute_blender_code calls):

• G grab/move, R rotate, S scale — moment-of-key activation; cursor anywhere on screen, you’re already in the transform state
• After G/R/S: tap X/Y/Z to constrain to that axis. Hold Shift while dragging for fine increments
• Shift+A add menu — primitives live under Mesh
• X delete (faster than the Delete key — finger-near-home)
• Tab toggle Object ↔ Edit mode (the most-used hotkey in Blender)
• 1/2/3 in edit mode → vertex/edge/face select
• Ctrl+R add loop cut (single click sets the cut, drag to position, click to confirm)
• I inset face (adds an inner loop on a single face — required when loop cuts can’t go on engons)
• Numpad . focus on selected object (or ~ then “view selected” if no numpad)
• F9 reopens the “last operator” panel (the bottom-left options box) momentarily
• Shift+Ctrl+S save as; +/- on numpad auto-increments the trailing number on filename (versioning trick)

Modifier-stack philosophy — non-destructive workflow:

• Solidify modifier adds thickness to thin meshes (the coffee-mug walls). The base mesh stays paper-thin; the modifier renders thickness on top.
• Subdivision Surface (subsurf) modifier doubles geometry per level and smooths corners. Start chunky (low-vert primitives) and let subsurf smooth — if you start high-res, subsurf compounds and becomes computationally heavy.
• To control subsurf smoothing distance: add loop cuts (Ctrl+R) near the corner you want to keep sharp. Subsurf averages between vertices; closer vertices = tighter edge.
• “Engons” (faces with >4 verts) are the dirty word — subsurf can’t predict their behavior. Fix by adding an inset (I) to convert the n-gon into quads at the boundary.

Mesh starting strategy:

• Pick the primitive that “most resembles” the target shape. Donut → torus. Mug → cylinder. Mailbox → cube. Lamp post → cylinder. This is the first instinct: never start with a cube and try to model a sphere.
• Adjust primitive parameters in the bottom-left “last operator” panel before clicking off — easier than rescaling later.
• Default cube is 2m. Default torus radius is 1m (way too big for a donut — set to 0.1m).

Shading:

• Right-click → “Shade Smooth” — fakery that smooths the appearance without adding geometry. Default is flat. Apply this to almost everything except where you want hard edges.

MCP-relevant Blender Python patterns implied:

• bpy.ops.mesh.primitive_torus_add(major_radius=0.1, minor_radius=0.057, major_segments=48, minor_segments=18) — the donut starting point
• bpy.ops.object.modifier_add(type='SOLIDIFY') then set thickness on the modifier
• bpy.ops.object.modifier_add(type='SUBSURF') with levels for viewport, render_levels for final
• bpy.ops.object.shade_smooth() for the smoothing pass
• bpy.ops.mesh.loopcut_slide requires Edit mode + an active edge — for MCP scripts, prefer bmesh.ops.subdivide_edges for predictable loop placement
