Your renders, hand-drawn. And they move by themselves.

Boil is a library of procedural toon shaders, outlines, drawn shading, effects, skies and compositor passes that boil: every texture re-draws itself every 2 frames and holds in between, the cadence of hand-drawn animation. No keyframes, no UVs, no image textures. Drag an asset onto your scene and press play.

Everything is drawn, not rendered: watercolor and marker washes, colored pencil, crayon, chalk and ink on paper. Ink is colored, never black. Shadows are tinted, never gray. Every color is an input.

154 animated materials

• Washes & paper: 26 watercolor washes, lined, graph and blueprint paper, aged paper, old-cartoon film print, misprint, and speckle, conical, freeform and palette washes
• Paint media: marker wash, gouache, ink bleed, watercolor salt, cauliflower blooms, masking-fluid resist, spray paint, stencil spray, ink spatter, sponge dab, paper marbling, batik, oil pastel, finger paint, painterly brush strokes, crayon resist, scratchboard, cross-stitch and eraser smudge
• Patterns & fabrics: wood, brick, lava, slime, scales, chrome, chalkboard, polka dots, plaid, wavy stripes, camo, terrazzo, glitter, tie-dye, knit, houndstooth, argyle, denim, a glitch pattern and more. Many have a Style menu with three looks
• Nature & objects: grass blades (meadow, lawn, wild), oil slick, cracked earth, snow and moss caps, cartoon ice, pool water, energy orbs, a cartoon eye that looks at a target (with iris and glint menus), cartoon glass, gems, a soap bubble, a cartoon globe, retro chrome, and cartoon gold, silver and copper

Flow: things that flow travel on twos

Lava, water, fire, clouds, smoke, beams and aurora travel forward one step per drawing and never repeat, while the drawn lines keep boiling. Every flowing material has a Motion menu (Flow on Twos, Flow on Ones, Boil Only), Flow Speed, Flow Direction and Flow Space (Object or World).

16 skies

Hand-drawn world backgrounds that boil on twos: clouds drift, stars twinkle, aurora ripples, snow and rain fall. Drop one on your World, or on any object.

Shade: 25 layers of drawn light and shadow

• Drawn shading on top of any Boil material: wash tones, ink-blot shadows, chalk rim light, inner line, hair shine, crevice pooling, depth wash and cartoon metal
• Glints in 12 shapes (circles, squares, window panes, stars, anime highlights and more), still or animated
• Hand-drawn media shading modeled on real marks: hatch, crosshatch, scribble, stipple, dots, pencil, crayon, charcoal, and a pressure shade where the strokes press harder as the shadow deepens
• Digital looks: ASCII, dither, pixel, airbrush and glitch, plus a Glitch Overlay that glitches any material, with a Calm / Default / Heavy / Custom intensity menu
• Shadows default to a lilac-leaning glaze of each color; switch Shadow Mode to set your own

44 line styles, two ways to draw

• 14 mesh outlines (one modifier per object): chalk ink, tapered brush, colored pencil, crayon, charcoal, dry brush, sticker, dashed, SquiggleVine, brush pen, ballpoint, marker and more
• 30 Grease Pencil line styles built on Line Art, with real gaps, overshoot, tapered ends and creases: sketch, tidy, rough + clean, construction lines, gesture, woodcut, stitched, rainbow and more. Every style can draw on / erase off with one slider

31 boiling effects (Geometry Nodes)

• Nature: clouds, bushes, grass tufts, wispy smoke, rocks, icicles, a wobble blob, falling leaves, lava-lamp blobs
• Particles, weather & energy: sparkles, confetti, fireflies, dust, rain, snow, electric charge, droplets, bubbles, wind streaks, lightning, a rainbow
• Animation craft: action lines, smear frames, squash & stretch, impact poofs, cartoon emotes, a sloshing potion and a burn-away dissolve. Motion effects follow your animation with no set-up
• Foam Ring: drawn foam where any object meets the water, with ripples that spread and fade

16 compositor passes & extras

• Passes for any render: paper & grain, ink edges, misprint, frame boil, pixel, dither, ASCII, glitch, onion-skin ghost trails and an inked vignette
• Hand-drawn lens flares, speech bubbles that fit your text, palette sets, comic panel borders, a sketchbook page and kraft paper

Made to be used

• Ones, twos or threes: everything ships on twos. Change Frames per Drawing on the Boil Clock and the materials, skies, ready-made lines and effects, and compositor passes all follow
• EEVEE and Cycles: flat items match in both engines. Shade layers draw your lights in EEVEE and render the flat color in Cycles
• Asset Browser ready: 780 assets, each with a thumbnail and tooltip, plus six demo scenes (day, golden hour, night, Haunted Patch, Harvest Table, Coffee Shop)
• No Python needed: works with Auto Run Python Scripts off
• Every control up front: each material's controls show right in Properties > Material, grouped into tidy panels (Style, Color, Look, Boil, Motion), with a tooltip on every one
• Your colors: fire, lava, water, sunsets and the other palette looks have a Custom Colors switch
• Readable node trees: the node graphs are organized into labeled sections, so you can open one up and see how it's built
• 12 months of updates, including free seasonal drops

Requirements

Blender 5.2 or newer (built and tested in 5.2 LTS). Grease Pencil lines use Line Art and need a scene camera. Motion effects must be baked before render-farm or command-line renders. Compositor passes need Compositing on and are designed for the Standard view transform. Mesh outlines need closed meshes.

Halloween drop: 62 new drag-and-drop assets, free

The free Halloween update adds 62 new drag-and-drop assets, hand-drawn, with boiling lines and effects: jack-o'-lantern and ghost materials, three night skies, bats, fog and wisps, a creepy wobble outline, a drip shade, a haunted film pass and 14+ ready-made models. Everything stays procedural, every color is an input, and the Boil Clock drives the animated ones.

The models are live geometry with shape sliders, and each one wears a Boil material, so you can build a haunted scene in a few drags.

What's new

• Halloween materials: Jack-o'-Lantern, Ghost Sheet, Candy Corn, Glow-in-the-Dark, Spiderweb, Bone, Tombstone, Mummy Wrap, Witch Brew and Haunted Wallpaper
• 3 Halloween skies: Harvest Moon, Harvest Moon Classic and Witching Hour, each as a World, an Object and a shader
• 4 boiling effects (Geometry Nodes): Bat Swarm, Ground Fog, Floating Eyes and Wisps
• 2 line styles: a Creepy Wobble mesh outline and a Creepy Wobble Grease Pencil line
• 1 shade layer: Drip
• 2 compositor passes: Haunted Film and Halloween Palettes (4 palettes)
• 14+ models: Pumpkin, Pumpkin Half, Trick-or-Treat Bucket, Ghost, Skull, Skull Classic, Witch Hat, Tombstone, Crooked Tree, Cauldron, Candle, Bat, and the Picket Fence in two versions (with and without posts)

The Halloween assets are filed in the Asset Browser under Boil > Holidays > Halloween. Six more model materials (bat body, candle wax, cauldron pot, dead tree, picket fence and witch hat) come along with the models. That is 62 new assets in all, taking the library from 489 to 551.

Thanksgiving drop: 58 new drag-and-drop assets, free

The free Thanksgiving update adds 58 new drag-and-drop assets, hand-drawn, boiling on twos with the Boil Clock, and every model now drops in: food and harvest materials, fall patterns, a cornfield dusk sky, rising steam, two compositor passes, 6 models and 5 fruit. Same rules as the rest of the pack: flat and procedural, and the materials boil on twos.

The models and fruit are Geometry Nodes, not meshes, and they come in two ways. Drag the drop-in object into empty space and it lands as a new object at that spot, or drag the node group onto an object to add it as a modifier, which replaces that object's shape. Either way, shape it with the sliders in Modifier Properties. They wear their own Boil materials already.

What's new

• 23 new drop-in objects (12 Halloween, 11 Thanksgiving): drag one into empty space and it lands as a new object with its base on the origin
• 6 food and harvest materials: Pumpkin Pie, Turkey Glaze, Cranberry Jelly, Corn Cob (Sweet, Flint or your own kernel colors), Wicker and Autumn Foliage (its Season slider turns the leaves from green through gold, orange and red to brown)
• 8 fall patterns: Buffalo Check, Harvest Stripe, Herringbone Tweed, Patchwork Quilt, Burlap, Maple Leaf Print, Acorn & Oak Print and Autumn Paisley
• 1 sky: Cornfield Dusk, as a sky card, an object material and a world
• 1 effect: Rising Steam, as a modifier and as a drop-in
• 2 compositor passes: Vintage Postcard (turns the render into an old printed greeting card with a cream border) and Thanksgiving Palettes (four seasonal color moods)
• 6 models, each as a drop-in and as a node group: roast turkey, pumpkin pie, corn cob, cartoon turkey, cornucopia (an empty horn, ready to fill) and gourd (four shapes)
• 5 fruit, each as a drop-in and as a node group: apple, bunch of grapes, orange, pear and plum

The Thanksgiving assets are filed in the Asset Browser under Boil > Holidays > Thanksgiving, with their own board (13 Thanksgiving) in Boil_Library.blend. Boil_Demo_Scenes.blend gains a finished scene, Boil Demo Harvest Table: a cozy harvest table built from the Thanksgiving assets, 48 frames at 24 fps, with its own camera, plus vertical and feed framings. The cornucopia in it is filled by hand with the new fruit models.

Rising Steam glows flat, so in Cycles it adds a little light nearby (the Tips section of the README covers the Ray Visibility switch).

That is 58 new assets. The full library is now 780.

Boil Café

The Café set adds 122 drag-and-drop assets in the same drawn style, including 35 models: coffee and pastry materials, deco wallpapers and tiles, skies, compositor passes, effects, shade layers and models for building a coffee shop.

Boil Demo Coffee Shop, in Boil_Demo_Scenes.blend, is a small isometric coffee shop built from the Café assets, with a Neon Night sign: 48 frames at 24 fps, with its own camera, plus wide, vertical and feed framings.

What's in it

• 15 materials: Brushed Brass, Chevron Tile, Chocolate, Coffee, Deco Fan Wallpaper, Deco Harlequin, Deco Marble, Glow Falloff, Icing, Kraft Print, Latte Art, Milk Foam, Pastry, Porcelain and Velvet
• 2 skies: City Street and Deco Sunrise
• 2 compositor passes: Cafe Palettes and Cafe Warm
• 5 effects: Bean Spill, Clink Sparkle, Coffee Pour, Coffee Steam and Sunbeam Dust
• 2 shade layers: Ceramic Gloss and Window Light
• 6 brewing models: Coffee Grinder, Espresso Machine, French Press, Milk Jug, Percolator and Pour Over
• 5 food models: Biscotti, Cake Slice, Cake Stand, Croissant and Donut
• 11 furniture models: Bar Stool, Bentwood Chair, Booth, Cafe Sign, Cafe Table, Counter, Deco Wall Panel, Deco Window, Menu Board, Potted Palm and Wainscot
• 3 lighting models: Deco Pendant Lamp, Deco Wall Sconce and Table Lamp
• 10 tableware models: Coffee Bag, Coffee Beans, Coffee Spoon, Deco Cup, Espresso Cup, Latte Mug, Saucer, Sugar Bowl, Sugar Cubes and To Go Cup

The models work like the Halloween and Thanksgiving ones: drag the drop-in object into empty space, or drag the node group onto an object, which replaces that object's shape. Deco Pendant Lamp, Deco Window and Menu Board keep their mounting point as the origin, so drop them where you want them mounted. Glowing items light the scene in Cycles.

The Café assets are filed in the Asset Browser under Boil > Cafe, with their own board (15 Café) in Boil_Library.blend. The model node groups are filed in their own folder in each set.

Neon Night

The Neon Night set adds 37 drag-and-drop assets in the same drawn style, including 4 models: halftone and cyberpunk looks, neon sign, data rain and hologram materials, optical camo and rain on glass, and a night-city sky.

Boil Demo Coffee Shop, in Boil_Demo_Scenes.blend, is a small isometric coffee shop built from the Café assets, with a Neon Night sign.

What's in it

• 7 materials: Ben Day, Cyber Slate, Data Rain, Hologram, Neon Sign, Neon Sign Halo and Screen Tone
• 4 compositor passes: CRT, HUD, Halftone and Teal Slate
• 1 palette pass: Neon Palettes
• 2 effects: Optical Camo and Rain On Glass
• 1 line style: Halftone
• 1 sky: Night City
• 2 shade layers: Anime Cel and Halftone
• 4 models, each as a drop-in and as a node group: CRT Monitor, Neon Sign, Noodle Bowl and Paper Lantern

The models work like the Halloween and Thanksgiving ones: drag the drop-in object into empty space, or drag the node group onto an object, which replaces that object's shape. The Neon Sign is a wall piece: it keeps its mounting point as the origin, so drop it where you want it mounted; it doesn't sit on the floor. Glowing items light the scene in Cycles.

The Neon Night assets are filed in the Asset Browser under Boil > Neon Night, with their own board (14 Neon Night) in Boil_Library.blend. The model node groups are filed in their own folder in each set.
