Letterer:

r2-shared-js/src/parser/epub.ts

Lines 1047 to 1053 in 096a56a

	case "ltr": {
	if (!publication.Metadata.Letterer) {
	publication.Metadata.Letterer = [];
	}
	publication.Metadata.Letterer.push(contributor);
	break;
	}

Penciller:

r2-shared-js/src/parser/epub.ts

Lines 1054 to 1060 in 096a56a

	case "pen": {
	if (!publication.Metadata.Penciler) {
	publication.Metadata.Penciler = [];
	}
	publication.Metadata.Penciler.push(contributor);
	break;
	}

Inker:

r2-shared-js/src/parser/epub.ts

Lines 1068 to 1074 in 096a56a

	case "ink": {
	if (!publication.Metadata.Inker) {
	publication.Metadata.Inker = [];
	}
	publication.Metadata.Inker.push(contributor);
	break;
	}

Commenting the above 3 code blocks will result in defaulting to a generic Contributor + Role (for example if the WebPub code letterer is used in the source publication):

r2-shared-js/src/parser/epub.ts

Lines 1089 to 1096 in 096a56a

	default: {
	contributor.Role = [role];
	if (!publication.Metadata.Contributor) {
	publication.Metadata.Contributor = [];
	}
	publication.Metadata.Contributor.push(contributor);
	}

...However this also means that Metadata.Inker|Penciler|Letterer will never be populated.
