Selecting Tools In Paint Tool Sai: Mastering The Bucket

how to bucket tool select in paint tool sai

The Paint Bucket Tool in Paint Tool SAI is a handy feature that allows users to fill in sections of their drawings with colour. While the tool is useful, it can be tricky to get it to fill in the exact area you want. Users have reported issues with the tool filling in the entire page instead of a specific section, as well as leaving behind small white gaps. To avoid this, it is recommended to first select the area you want to fill using the Magic Wand Tool, and then use the Paint Bucket Tool to fill in the selected area. This ensures that the colour stays within the desired boundaries.

Using the Magic Wand tool to select outside your line art

The Magic Wand tool in Paint Tool SAI is an excellent way to select areas outside your line art for editing. Here's a step-by-step guide on how to use it effectively:

Step 1: Accessing the Magic Wand Tool

To begin, locate the Magic Wand tool in the selection toolbar of Paint Tool SAI. It is a versatile tool that allows you to select areas with different detection modes.

Step 2: Understanding Detection Modes

The Magic Wand tool offers three detection modes: Transparency (Strict), Transparency (Fuzzy), and Color Difference. The first two modes are less commonly used, so it is recommended to switch to Color Difference. This mode enables you to select areas based on their colour, and you can adjust the strictness of colour selection using the "Color diff." bar.

Step 3: Selecting Outside Your Line Art

With the Magic Wand tool selected, click on the area outside your line art that you want to edit. This will create a selection that you can modify further. You can adjust the size and opacity of the selection tool to fit your needs.

Step 4: Inverting the Selection

After making your initial selection, use the Invert function to reverse the selected area. This is particularly useful if you want to edit the background or areas outside your line art. The "Invert" function ensures that you are only modifying the desired regions.

Step 5: Refining the Selection (Optional)

If you want to fine-tune your selection further, you can use the Increment tool. By selecting outside your line art and clicking "Increment" a few times, you can make the selection bleed slightly into the line art. This helps prevent colour leakage when you start editing.

Step 6: Filling the Selected Area

Once you are happy with your selection, it's time to fill it with colour. You can use the paint bucket tool for this. Ensure that your selected area overlaps your line art by 1-3 pixels to avoid any gaps. Then, use the paint bucket tool to fill the selected area with your chosen colour.

Remember to experiment with the different settings and modes of the Magic Wand tool to become more familiar with it. With practice, you'll be able to master selecting outside your line art and create stunning digital artwork in Paint Tool SAI.

Inverting the selection and using the bucket fill

It is important to note that the bucket fill tool in Paint Tool SAI Ver 2 functions differently from Ver 1. In Ver 2, the bucket tool may fill the entire page instead of filling just inside the coloured outline. To address this issue, the gap tolerance can be adjusted to a higher value.

Another approach is to create a new layer after applying a base fill colour and clipping it to the base colour. Then, the selection source can be set to the line art, and the bucket tool can be used on the new layer. This method may be more effective in certain situations.

Additionally, there is a shortcut for Layer -> Fill, which is Ctrl+Backspace by default. This shortcut will fill the selected area with the foreground colour.

When using the bucket tool, it is worth noting that it functions as a brush with adjustable settings. By accessing the brush settings, users can modify parameters such as "dilution" and "blending" to control the range of the fill. However, a more effective method involves utilising the selection wand tool to choose the desired area for filling. After making the selection, go to Selection -> Dilate Selection and adjust the settings so that the blue selection pixels overlap the line art by 1-3 pixels. Once the desired overlap is achieved, confirm the selection and proceed to fill the chosen area with the bucket tool.

Using the selection wand to select the area to fill

The selection wand tool in Paint Tool SAI is a versatile tool that can be used in various ways to select areas to fill with colour. The tool has three different detection modes: Transparency (Strict), Transparency (Fuzzy), and Colour Difference.

To use the selection wand tool effectively, start by adjusting the settings to suit your needs. For instance, you can change the size, opacity, and pen pressure of the tool, as well as add texture if desired. The "Colour Diff." bar allows you to adjust how strict the colour selection is, which is useful when you want to select a specific coloured area or all areas with similar colours.

Once you have the desired settings, you can begin selecting the area you want to fill. Click and drag the selection wand tool over the area you want to fill, creating a rectangular selection. If you need to select a more precise area, you can use the Selection Source option to set the layer as the detection target. This ensures that only the selected layer is affected by the tool.

After making your selection, go to the top menu bar and select "Selection" -> "Dilate Selection by" to expand the selection slightly. Adjust the settings so that the blue selection pixels overlap your line art by 1-3 pixels, then click "OK".

Now, you can use the paint bucket tool to fill the selected area with your chosen colour. This method ensures that the paint bucket tool fills the entire section within your line art, without leaving any pixelated white line gaps.

Additionally, you can use the Invert and Increment tools in combination to refine your selection further. By selecting the outside of your line art and inverting the selection, you can then use the "Increment" tool to make minor adjustments and prevent colour bleeding.

Dilating the selection to overlap line art

To use the bucket tool to fill in sections of your colouring in Paint Tool SAI, you must first use the magic wand tool to select outside your line art, then invert the selection. Then, you can bucket fill the piece with a single basic colour.

Next, take the colour you need and outline the section with that colour. Then, use the selection wand and select the area you want to fill. Go to the top of the page and hit 'selection -> dilate selection by...' and make the blue selection pixels just overlap your line art by 1-3 pixels. Hit 'ok', and then use the paint bucket to fill the selected area.

You can also make another layer after doing a base fill colour and clip it to the base colour. Then, set the selection source to the line art and use the bucket on the new layer.

Using the bucket tool on a new layer

To use the bucket tool on a new layer in Paint Tool SAI, you must first select the lineart layer. Then, click on the Magic Wand Tool (the red box above the brushes) and choose the areas you want to colour. You can also use the selection wand to select the area you want to fill and then hit 'selection' at the top to dilate the selection so that it overlaps your line art by 1-3 pixels.

Next, create a new layer for filling in the colour. You can do this by going to 'Layer' and then 'Fill', or by using the shortcut 'Ctrl+Backspace'. This should fill the selected area with the foreground colour.

If you want to use the bucket tool on multiple sections with different colours, it is recommended to create a new layer for each colour. This makes it easier to add shadows later on.
