Cel Shading Resin Figures: Clear Shapes and Shadows

Cel shading describes form with distinct areas of colour and clear shadow boundaries. On a resin figure, the challenge is deciding where those shapes belong. A black line around everything will outline the sculpt, but it will not make the lighting coherent.

This guide treats cel shading as a painting exercise for display figures, with three useful practice areas: a cloak, a section of hair and a simplified face. Each asks a different question about shape and light. You can work through them on separate studies without committing a whole figure to an unfamiliar style.

Remerlinds supplies unpainted resin figure kits. The coloured shapes and graphic shadows described here are work you add yourself; the project-selection section explains what to look for in a sculpt. Start with one small study and use its result to plan the next area.

Set a viewing angle and a light direction

Choose the main display view before mapping the shadows. Put the figure where you can look at it from that angle, then choose a single imagined light direction for the painted design. Keep a small sketch or arrow beside your work so that direction stays consistent as you turn the model.

The actual room light will still fall on the finished sculpture. Your painted shadows are a separate design laid over that three-dimensional form. They should remain intelligible from the intended view, even though the real highlights shift when someone moves around the display.

Use a photograph or a simple outline sketch to plan large shadow regions before painting them. A photograph taken under one lamp can offer a starting reference, but do not copy every tiny reflected patch and surface irregularity. Select the boundaries that explain the pose. The aim is a clear design that you can paint deliberately.

For a first study, choose a light direction that makes the main planes easy to distinguish. If the face, cloak and hair all demand complicated little shadow islands, simplify the study or change the view. A manageable plan is more useful than a dramatic diagram you cannot interpret on the actual sculpt.

Mark the main view on your sketch, not on a fragile part. Return to it after working on a side or back surface. It is easy to make a local shadow look attractive while forgetting how it joins the larger colour area around the figure.

Build a small set of distinct colour values

Begin with a main colour and a clearly different shadow colour for one material. Add a lighter accent only if it helps describe the form. Two readable regions are enough for the first exercise; a third should have a job rather than becoming a stripe on every surface.

Test the colours next to each other on a separate sample. Let them dry, then inspect the boundary at your intended viewing distance. If the two areas merge visually, increase their difference or simplify their shapes. Choosing another hue is not the same as creating a useful light-dark separation.

A shadow does not have to be black. A darker relative of the main colour, a cooler or warmer mixture, or a deliberately graphic colour can all be choices to explore. Judge the result beside the main colour and the neighbouring costume areas. There is no compulsory shadow recipe that fits every blue cloak or skin tone.

Keep the first palette small enough to remember. Label a sample with the main colour, shadow and optional accent. You are building a reference for one material, not an inventory of every paint you own. Repeat the same relationship on a spare shape before adding another material to the study.

Key takeaways

• Choose a main display view and keep a light-direction reference.
• Test adjacent colours after they dry.
• Add a third region only when it clarifies the form.

Exercise one: map a cloak with broad shapes

A cloak study is about grouping folds into a few readable regions. Start with a flat drawing or a spare practice surface, then transfer the idea to an accessible area of the figure. Follow the large change of direction in the cloth rather than outlining every sculpted groove.

Draw a simple cloak silhouette on paper and divide it into a main colour and one shadow region. Give the shadow a clear beginning and end. Look for a shape that could be recognised at a glance: a wedge under an overhang, a broad side facing away from the light, or a dark interior behind the main fold.

On the figure, compare that plan with the actual geometry. A fold can turn through several directions, so your flat sketch will need adapting. Keep the main shadow connected where that helps the design. Avoid adding tiny bright islands merely because the sculpt has a raised detail there.

Paint the main colour first and establish the large shadow boundary on a test area. Let the application dry before correcting its edge. Use the main colour to refine the shadow shape if that is easier than trying to place the entire boundary perfectly in one stroke.

Once the two main regions read clearly, consider a limited light accent on an exposed fold. Check it against the chosen light direction. If the accent fragments the cloak into several unrelated stripes, remove or shorten it. A successful study can remain simple even when the sculpt has much more detail available.

Exercise two: treat hair as grouped masses

For a hair study, begin with the overall mass rather than individual strands. Decide which large section faces the chosen light and which falls into shadow. The sculpt's strand detail can remain visible beneath the paint without every groove needing a dark line.

Choose one accessible section, such as a fringe or a broad side lock. Sketch a compact shadow shape that follows its turn. Compare that shape with the head and face below it: a hair shadow should make sense in the same lighting arrangement as the rest of the figure.

Place a highlight shape only after the main and shadow colours work together. It can be a narrow band, a wedge or a small connected patch, depending on the design. Keep its shape intentional. A row of disconnected bright dots may suggest texture rather than the graphic reflection you had in mind.

Turn the figure to check where a band crosses separate locks. You may want the shape to continue visually across them from the main view, while allowing actual gaps in the sculpt to interrupt it. This is a compositional choice to test, not a requirement to paint through every recess.

Keep hair and face readable as separate areas. If their values are too similar, a slightly darker boundary or a different hair shadow can help. Do not automatically thicken the outline until it dominates the forehead. Return to the larger colour relationship first.

Exercise three: simplify a face without losing expression

A face study asks for restraint. Begin with the largest readable planes and the features that carry the expression. Use a sketch or separate practice face before experimenting on the most important part of your display figure.

Choose a main skin colour and a tested shadow that remains distinct without looking like an accidental stain. Map a limited shadow under an overhang or on the side turned away from the chosen light. The exact boundary depends on the sculpt and pose; a diagram for one face is not a universal template.

Keep the eyes, mouth and brows clear enough to judge the expression before adding more graphic marks. On a stylised chibi, those features can occupy a large part of the design. A heavy cheek line that looked harmless on paper may change the expression when placed beside an eye.

Inspect from the intended display distance as well as close up. If the face reads as several disconnected patches, simplify the colour regions. If it reads clearly but seems unfinished under magnification, resist adding marks without a specific purpose. A display view and a macro photograph ask different things of the same painting.

You do not have to use equally strong outlines on every material. A softer division on the face can sit beside harder costume boundaries if the result is coherent. Decide that relationship intentionally and keep a sample or photograph of the approved study as a reference.

Use outlines to separate forms, not replace shadows

Outlines can help distinguish adjacent shapes, but they are separate from the shadow design. Decide where a line clarifies an overlap, edge or facial feature. Then decide its thickness and colour for that particular place.

A dark line between a sleeve and torso can make their separation legible. The same thickness around every finger may hide the hand's shape. Test the line on a spare surface first, using a mark similar in length and curvature to the one you intend to paint.

Keep the darkest marks in balance across the figure. If only one shoulder has a very heavy outline, the eye may keep returning there. That can be useful for a focal accessory, but distracting if the face is meant to lead. Review the whole figure after each group of lines rather than completing every edge in isolation.

Repair a wandering line with the adjacent base colour after the paint has dried sufficiently for the product you are using. Work towards a clean boundary rather than trying to hide it under another wider line. There is no speed target for these exercises; a small, controlled correction is part of the process.

Key takeaways

• Use lines where they clarify a real overlap or feature.
• Keep line thickness appropriate to the area.
• Check the whole figure before making another boundary darker.

Check the design as a whole

Pause after one material is complete and compare it with the rest of the planned palette. Clear local shapes can still compete with each other across the figure. The main view should tell you where to look without every region demanding equal attention.

Take a simple progress photograph with consistent lighting and framing. Use it to compare the planned shadow map with the painted one. A greyscale preview can help you notice merged light and dark regions, but it is only an aid; camera processing and lighting can change their apparent relationship.

Check a side view too. You do not need to make the painted design equally dramatic from all directions, but abrupt unexplained stops may need refining. Follow a shadow around a curved surface until it meets a believable boundary in your chosen design.

Before coating the finished figure, test the intended finish over a spare sample of the colour scheme. Check compatibility and drying instructions for the actual products. A surface finish changes how the real light plays across your graphic painting, so choose it with the same care as the palette.

Choose a kit for the shapes you want to practise

Look for a sculpt with accessible areas and forms you can read easily. A broad cloak, a clear fringe or an expressive stylised face gives you a specific exercise to plan. A larger figure is not automatically easier if the pose blocks the brush from the area you want to study.

The chibi collection is a useful place to explore exaggerated shapes and expressions. The anime figure kit collection offers other costume and hair designs. Inspect each listing and choose the subject first; these collections are starting points, not a promise that every kit has the same part layout.

All kits arrive unpainted. Choose Bronze, Silver or Gold according to the preparation work you want to take on, then plan any assembly seams and painting access before colour. You do not need to wash a delivered Remerlinds kit as a standard painting step.

The scene illustrations in this guide show generic practice ideas rather than a purchased kit or a tested product result. Use their simple colour divisions as a prompt to make your own sketch. The actual sculpt in front of you determines where the boundaries belong.

Draw the first shadow before opening the paint

Choose one practice area and make a simple two-colour sketch from the main view. Mark the imagined light direction. Put the two dried paint samples beside it and check that their boundary reads clearly.

Then paint that one area, inspect it from the display view and make a specific correction if it needs one. Keep the successful sketch and sample for the next section. You can build a coherent figure one readable shape at a time.
