Minecraft slime render

A cube of translucent green jelly with a smaller, sadder cube set inside it.

A free slime render is one URL away, as a PNG with a transparent background. Below are its 4 poses, its 2 variants, a side profile and the model's size in pixels and blocks, each image drawn live from the URL under it.

Minecraft slime render: the full body in 3D, standing, on a transparent background — Both live: `/render/mob/slime/body` and `/render/mob/slime/head`.

Minecraft slime head render: the head alone in 3D, as a square PNG — Both live: `/render/mob/slime/body` and `/render/mob/slime/head`.

The URL

The slime is drawn from its name, not from a profile, so there is nothing to look up and nothing to resolve: the two URLs below are the whole interface. The camera defaults to yaw 30° and pitch 14°, the angle this model reads best from, and a body render is 1.1 times as wide as it is tall unless you say otherwise.

text

https://skinrender.dev/render/mob/slime/body
https://skinrender.dev/render/mob/slime/head

Either type may end in .png, and /render/mob/slime on its own redirects to the body render. Add size= for any height between 8 and 1024 pixels, bg= for a solid background instead of transparency, and crop=true when you want the image trimmed to the slime itself.

Minecraft slime poses

pose= takes 4 names on the slime: default, walk, hop and squash. Every mob answers to default and walk; the rest are this model's own, and another mob's pose name is a 400 rather than a silently wrong picture.

Default pose

pose=default
Standing still.
Walk pose
anim
pose=walk
Mid-stride walk cycle; use frame to pick the phase.
Hop pose

pose=hop
Tipped back on the launch of a hop, the way it moves at all.
Squash pose

pose=squash
Landed and leaning hard to one side, still wobbling.

The poses marked anim are cycles rather than fixed positions: frame=0..1 picks the phase, and fit=false keeps the camera still between frames. Animation covers both that and the animated-PNG format.

Variants

variant= chooses which slime to draw. There are two, and normal is what you get without the parameter.

variant=normal
variant=magma

A variant is a different texture on the same rig, so poses, camera and everything else behave identically across all of them: /render/mob/slime/body?variant=magma&pose=walk.

Side profile and other angles

yaw turns the camera round the slime and pitch tips it up or down. The default is the three-quarter view above; yaw=90&pitch=0 is a flat side profile, yaw=0 the front and yaw=180 the back. Any angle in between works the same way, and so does any pose.

Side profile
yaw=90&pitch=0
Front
yaw=0&pitch=0
Back
yaw=180&pitch=0

Slime dimensions in pixels and blocks

Measured from the model this page renders, in its default variant (normal), in model pixels, 16 to a block. Standing in the default pose the slime is 12 pixels tall (0.75 blocks), 12 wide and 12 from front to back. The models are built in code for this site rather than extracted from the game, so these are the sizes of this slime, not numbers read out of the game's files.

Part	Count	Size in pixels (w × h × d)	Size in blocks
Whole slime	1	12 × 12 × 12	0.75 × 0.75 × 0.75
Body	1	8 × 8 × 8	0.5 × 0.5 × 0.5
Shell	1	12 × 12 × 12	0.75 × 0.75 × 0.75

Part sizes are each box as it is built, before the part is turned into its pose.

Using a slime render

People want a minecraft slime render at one of two sizes. Small — 64 or 128 pixels, usually the head type — for a list, a legend or a table of what spawns where. Large — 512 pixels of body, often with crop=true so the PNG is exactly as big as the model — for a banner, a wiki page or a card. Both are the same endpoint with a different size.

The other ways people ask for this image — slime png, slime cube image, magma cube render — are the same URL with a parameter changed rather than a different endpoint, which is the point of building the whole thing out of one address.

html

<img src="https://skinrender.dev/render/mob/slime/head?size=128"
     width="128" height="128" alt="A Minecraft slime" loading="lazy" decoding="async">

The response is a PNG with a transparent background, Access-Control-Allow-Origin: * and a year-long immutable cache, because a mob render depends on nothing but its URL and so can never go stale.

Parameters

Every parameter the slime accepts, generated from the same table the parser reads. All but pose and variant are the ones a player render takes, and anything that describes a skin — layers, capes, arm model, fallbacks — is not in the list and is reported back in the X-Ignored-Params header if you send it anyway.

Output

Size, background and how the file is delivered.

Parameter	Values	Default	What it does
`size`	`8 – 1024`	`body 512, head 256`	Height of the image in pixels. Width follows the render type’s aspect ratio unless width is given.
`width`	`8 – 1024`	`none`	Explicit width in pixels. Overrides the aspect ratio derived from size.
`height`	`8 – 1024`	`none`	Explicit height in pixels. Overrides size.
`bg`	`hex colour`	`none`	Background colour as 3, 4, 6 or 8 hex digits (with or without #), or transparent.
`aa`	`1 – 4`	`2`	Supersampling factor for smoother edges. 1 disables anti-aliasing and is fastest. Lowered automatically so that aa² × width × height stays within 4,194,304 (2048×2048) pixels.
`crop`	`true \| false`	`false`	Trim fully transparent rows and columns from the edges of the finished image. With format=apng every frame is trimmed to the same rectangle, the union of their bounds, so the animation does not jump.
`margin`	`0 – 0.45`	`0.05`	Fraction of the canvas kept empty around the auto-framed model.
`mirror`	`true \| false`	`false`	Mirror the finished image horizontally.
`download`	`true \| false`	`false`	Send the image as an attachment so browsers save it instead of displaying it.
`filename`	`text`	`none`	File name used with download. Letters, digits, dashes and underscores; the .png or .apng ending is added.
`format`	`png \| apng`	`png`	File format: png is a single still image, apng an animated PNG that plays one loop of the pose. apng needs an animated pose (walk, run, dance or wave), makes frame meaningless and turns fit off unless you ask for it; a .apng ending on the path means the same thing.
`frames`	`2 – 60`	`16`	How many frames one loop of an animated PNG is sampled at. frames × width × height must not exceed 16,777,216, and aa is lowered automatically so that aa² × frames × width × height stays within 33,554,432.
`fps`	`1 – 50`	`20`	Playback rate of an animated PNG in frames per second, written into the file to the nearest millisecond.
`loop`	`0 – 100`	`0`	How many times an animated PNG plays before it stops on the last frame. 0, the default, plays it forever.

Camera

Where the model is viewed from. 3D renders only.

Parameter	Values	Default	What it does
`yaw`	`-360 – 360`	`35`	Turn the model about its vertical axis, in degrees. 0 faces the camera; positive turns its right side toward you.
`pitch`	`-360 – 360`	`12`	Tip the model toward or away from the camera, in degrees. Positive looks down on it from above.
`roll`	`-360 – 360`	`0`	Rotate the whole image about the viewing axis, in degrees.
`fov`	`0 – 120`	`0`	Vertical field of view in degrees. 0 is orthographic; 30–50 gives a natural perspective, larger values exaggerate it.
`zoom`	`0.1 – 8`	`1`	Multiplier on the auto-framed size. 2 doubles the model on the canvas.
`offsetX`	`-2 – 2`	`0`	Shift the model horizontally by this fraction of the canvas width.
`offsetY`	`-2 – 2`	`0`	Shift the model vertically by this fraction of the canvas height. Positive moves it down.
`fit`	`true \| false`	`true`	Auto-frame the posed model so it fills the canvas. With fit=false the camera stays fixed, so animations do not jitter between frames.

Lighting

Shading and shadow.

Parameter	Values	Default	What it does
`shading`	`0 – 1`	`1`	Strength of the per-face shading that gives the render depth. 0 is flat, 1 matches the in-game inventory look.
`shadow`	`true \| false`	`false`	Draw a soft drop shadow under the feet.

Pose

Named poses and per-joint rotations, in degrees by default.

Parameter	Values	Default	What it does
`frame`	`0 – 1`	`0`	Phase of an animated pose (walk, run, dance, wave) from 0 to 1. Step it to render the frames of a GIF.
`units`	`deg \| rad`	`deg`	Unit for every angle parameter: degrees or radians.
`pose`	`default \| walk \| hop \| squash`	`default`	A named pose of the Slime. Any other mob's poses are rejected, so the list is per mob.
