IMPORT: 3D Studio files
A .3ds file opens the 3D Studio Import window: the file's objects with their kind and material count, filtered by kind or name, checked one by one or all at once, where to put them on layers and what a mesh with several materials becomes. Checked meshes come in as polyface meshes on the chosen layers with materials made from the file's colours, cameras as named views; a mesh with several materials is split, given its first material, given none, or asked about on the command line. Automation drives the window with tds_import_dialog. Co-Authored-By: Claude Opus 5.5 <[email protected]>
