My understanding is when applying an SVG modifier to a part in Bambu Studio, it collapses all paths to a single “object” that cannot be separated.
The only way to make this work is to bring in each color separately. But then scaling and aligning each color is manual and very inaccurate.
There should be a way to bring in a multi path / multi layer / multi color SVG and allow each to be assigned a color.
The “workaround” is to bring in the SVG as a “part” and then it retains the structure. Then assign the colors and lay it on the plate. Then drop the part on top of it and merge them. Works for flat parts but not for curved parts.
