為甚麼在 Krita 重新着色武器也會改變角色？

Disclosure: This draft was generated with AI and checked against the cited primary sources, with a separate AI editorial review. It was prepared for the FrameSprite team, which has a commercial interest in FrameSprite. Proposed examples are not executed tests unless explicitly identified as recorded fixture results.

A filter layer can affect artwork below it, including the character you meant to leave alone. For an accessory-only adjustment, attach a filter mask to the accessory's layer, or deliberately isolate the intended layers in a group. Moving the filter near the weapon in the layer stack is not enough to establish its scope.

Key Takeaways

• Decide whether the correction belongs to one layer, a group or the whole composite.
• Layer hierarchy and group compositing matter more than a filter's descriptive name.
• Check unchanged skin, clothes and outlines as well as the recolored accessory.

Find the pixels that actually own the weapon

Save a .kra copy and temporarily hide the accessory layer. If part of the weapon remains visible, its pixels belong to more than one layer. If the character also disappears, the accessory was flattened into the same paint layer. A filter cannot infer which pixels represent metal, fabric or skin from your layer's name.

For flattened AI artwork, create a careful selection or separate the accessory first. Preserve an unmodified source. Do not invent a layer-isolation solution when the source contains only one composite image; the preparation step is part of the work.

Choose correction scope deliberately

The official Filter Layer manual explains that a filter layer acts on underlying content and can be constrained through grouping. A Filter Mask provides a different structure: a filter attached to a particular layer with a mask controlling its affected area.

For a sword on its own paint layer, begin with the mask approach. For a weapon assembled from a blade, gem and trim, a group-level correction may be easier to maintain. Inspect the group rather than assuming it is isolated: Krita's Group Layers documentation distinguishes normal group compositing from pass-through behavior.

These are workflow recommendations, not promises that every filter produces a useful material recolor. Hue changes can alter highlights and reflected colors in ways that need manual review.

Make a controlled variant comparison

As an unexecuted example, consider a bronze sword being converted to a blue ceremonial version. Pick three comparison locations: blade midpoint, glove and face. Before applying the correction, export a baseline with fixed canvas dimensions. Apply the filter only to the weapon structure and export the variant using the same settings.

Compare the glove and face at identical positions. If they change, inspect filter ownership, group boundaries and any duplicated correction above the group. If only the blade changes but its highlight becomes implausible, the scope is correct and the color treatment needs revision. Those are different failures and should lead to different repairs.

Reopen the variant PNG independently. A correct native layer arrangement is useful, but the delivered projection is what another developer imports. Check the weapon's overlap with the hand and whether semi-transparent glow changes nearby colors when composited.

For adjacent issues, see empty groups and alpha inheritance, clone-layer glow sources and palette variant readability. Keep the editable correction in the native source and give the exported variant a distinct name. This guide describes an inspection method; it does not report a completed Krita test.
