Description
When I'm using a bone to adjust the UVs, I don't want that bone to interpolate between keyframes. But the interpolation is unavoidable with the current importer.
Example: Say I want to make a bone position decides the expression of a character. If the bone doesn't jump exactly to the position of the next UV, the texture will be displayed in an incorrect position.

Research direction
No file, test, or entry point is named. Start by locating the current importer and tracing how bone-driven UV values are interpolated between keyframes. Done means the importer supports constant interpolation so UV-related bone positions can jump to the next keyframe without intermediate texture positions.
