Feature 2 · Asset library

Where the asset library is and what is in it

How to open it

Among the small buttons at the top-right of the canvas, find the "Sketch library" icon and click it.

Or use the menu: File → Sketch library.

What is inside

A large set of black line drawings on transparent background: flowers, animals, fruit, landscapes, anime characters.

They are not finished artwork. They are a base for tracing, colouring and practice.

The drawings are transparent, so you can drop them over a background colour and paint on a layer underneath — the lines always stay on top

Line art plus reference: how dual images work

Some assets carry two images

Apart from the line art, some assets also ship a finished colour reference.

Those cards have a blue overlapping-images icon at the top-right. Click it to switch between line art and the color reference.

Typical workflow

Put the reference next to it and study where this flower is dark and where it is light

Switch back to the line art, add a layer underneath, and paint following those tonal relationships

Hide the reference layer when done — what remains is your own painting

To trace

Drop the line-art layer to about 30% opacity, add a layer above it and ink your own lines, then delete the underlay.

The reference shows you colour relationships, not colours to copy. Copying the colours literally makes the result look muddy

Find assets by style and subject

Two filters

Style: all / sketch / watercolor line / ink line

Subject: changes with style. Sketch offers plants, animals, fruit, scenes, patterns, anime;

watercolor offers landscape, still life, flowers, animals, people; ink offers landscape, birds and flowers, fish and insects, plants, beasts

Fastest way to use it

Pick the style first, then the subject. What is left is a dozen or so thumbnails you can scan at a glance.

If it is not there, it is not there. See "add your own" below

Add your own drawings to the library

Three steps

1. Find the data\sketch folder next to the program

2. Drop your PNG in (transparent background, black lines work best)

3. Restart the app — it shows up under the sketch style

To give it a Chinese name

Put a names.txt in the same folder, one line per file: "filename=Chinese name", saved as UTF-8.

To add a reference

Create a references subfolder and name the file "lineartname_reference.png".

The app pairs it with the line art automatically.

Avoid JPG: no alpha channel, so it lands as an opaque block covering everything below

It is a plain directory scan — no config to edit. Drop a file in and it appears; delete it and it is gone
