Getting Started

General Information

Graphic artists usually meet on the artwork development forum or on the restricted art development forum. The former is a great place to post and discuss new and current Wesnoth art and graphics, and the latter to see what the art development team is working on.

Unit and terrain art is stored in the portable network graphics (PNG) format. Each frame of a unit animation, and each variation of a terrain is stored as a separate .png file in the "images" subdirectory of wesnoth, and generally these files will be 72 x 72 pixels (the size of Wesnoth's basic hexagonal tile) with an alpha channel (a part of the file that indicates how transparent each pixel is). When creating your own images, you can test them without overwriting any game data by putting them in your userdata directory (see EditingWesnoth for details on Wesnoth's directory structure). The game also supports JPEG images, though these are better suited for story art.

To edit these graphics, you'll need some program capable of creating PNGs - some of the programs in the following list are free, open-source software, and will do the job nicely: Art Programs

If you need some inspiration, we have a Graphics Library which collects art posted on the forum. You can use this for ideas, and as a scrap heap for different parts of unit images (a technique described here).

Roadmap

A list of what's being done and what needs doing:

Tiles Status - a roadmap/plan of sorts for future work on terrain tiles
A list of current work that needs to be done with sprites.

Art Tutorials

These are a work-in-progress, and describe both how to make art fit into wesnoth's style, as well as giving some considerable tips on drawing in general. Especially useful is the External Tutorials page which lists a large number of art tutorials available on the web.

General Art and Computer Graphics

Using the Levels Adjustment - making scanned pencil drawings not look washed out.
Extending dynamic range - The Grooviest (so far) tutorial about extending the dynamic range of images and how this technique can be used to make better scans of pencil drawings.
Scanning with camera - How to transfer real-life art to computer using a digital camera instead of a scanner.
How to Anti-Alias Sprite Art - A means of removing the jagged edges on pixel lines
Art Supplies - What physical items you need to do larger cell-shaded art like that of Jetryl/Jormungadr/et al
Computer Inking a Sketch - Info from Jason Lutes on his portrait workflow
Scaling Digital Images - how to properly resize an image on a computer
How to Shade - at attempt at tackling a very complicated topic
How to make Wesnoth-style Maps - Kestenvarn's tricks of the trade
Designing weapons and armour - Advice from zookeeper on designing realistic weapons for your characters
Portrait Tutorial - a guide on how to draw unit/character portraits by Kitty.
Sgt. Groovy's vector workshop - tips and tricks for drawing with Inkscape
- Z-order tricks - few methods for faking overlapping shapes
- Variable-width strokes - how to make the strokes vary in width, like being drawn with a flat-tipped pen — no tablet needed!
- Shaped gradients with Gaussian blur - how to make gradients in other shapes than linear or radial
- Smooth shading in vector - the basic vector techniques for smooth shading, employing Gaussian blur and clipping/masking
- Vector Inking - vector techniques, including mouse-only, for inking your sketches
- Making portrait art in vector - a complete tutorial for making Wesnoth unit portraits in vector graphics.

Terrain Graphics

The following is information specific to drawing terrain for Wesnoth. Read Frame's "Tiles Tutorial" for a good overview of how terrain graphics work.

Tiles Tutorial - Frame's tutorial describing the process of making terrain tiles in wesnoth, and how they interact with adjacent tiles.
How To Make Seamless Tiles - The tutorial is aimed at Photoshop users, but the technique is similar with The GIMP.
Seamless Tiles Using Inkscape - This tutorial teaches a method for making seamless hex tiles in vector craphics (to be rendered in raster).
Turning Square Tiles into Hex - Nifty tricks for transforming square (or any rectangle) shaped seamless tiles into hexagon seamless tiles.
Castle Tutorial - A description of how Wesnoth's castle tiles work (needs updating, but useful nonetheless)
Multi-Hex Tiling Tutorial - A description of how multi-hex tiles work.
Editing Castles - Instructions for how to make/edit castles (and other corner-based terrains) using yobbo's GIMP script.

These describe the system used to specify how terrains behave in game:

TerrainCodesWML - A list of the letters used to represent terrain types.
TerrainGraphicsWML - If you really need to get technical, start here.
Ayin's Terrain Graphics document - If you really, really need to get technical, this describes the terrain graphics WML system in depth.

Sprite Art

The following are different tutorials about sprite work compiled by various wesnoth sprite artists. These will give you the most specific-to-wesnoth information about making sprites, and are well worth a read.

Creating Unit Art - a list of specifications you will need to match.
Give Your Hero A Personality - tricks for editing existing images, including some clip art.
Basic Animation Tutorial - or "How to Animate Sprites for Dummies," covering the basic theory, and all of the mistakes to avoid.
Advanced Animation Tutorial - how to wire in the animation frames to units in a way that makes the animation look good in-game. Doesn't cover any drawing as such, but focuses on timing conventions and some standard techniques for getting as much as possible out of the frames that are already drawn.
Team Color Shifting - how to use our new team color system.
Creating Shadows Under Units - how we create the shadows for the units in-game
Making Bow Animations - the current standard for how we want bow animations to work
Rotate Pixel Art Without Blurring
Creating a scratch built sprite - an attempt to show some ways creating a sprite from scratch
How to create motion blurs - a simple explanation on how to create attack animation weapon blurs
FrankenPacks - a quick and dirty way to create sprites for UMC

External Tutorials

The following page contains dozens of links to tutorials covering all manner of artwork, including sprite art. These were not made by wesnoth artists, but should prove very useful for general instruction.
