Export as Collada
Firestorm allows objects (linksets) to be saved to your hard drive (exported), and brought back into SL (imported), with restrictions to prevent content theft.
The purpose of export/import is to allow you to create backups of your creations on your own system, in case of SL inventory loss, or to allow you to transfer your created items to other grids.
Exported objects must belong to you, and all parts made by you or export will fail.
All textures on the object must be in your inventory, and be made by you. This includes sculpt maps.
Any items contained inside the object (eg, scripts, notecards, etc) must also be made by you.
To export an object to your hard drive, right click it and select Save As from the menu. Then select Collada.
A window opens, showing the properties of the item, and giving a few options:
Save textures: Enable this if you wish to save the textures which are applied to the object.
Note that this will be greyed out if you are not allowed to export the textures.
Consolidate textures: If enabled, combines multiple faces having the same texture, into a single material. Otherwise, each prim face will have a unique material identifier. (Remember that L mesh import only supports a maximum of 8 materials when importing.)
Skip Transparent: Ignore (do not export) any faes what are set to transparent.
Apply texture params: When exporting, preserve any special texture paramaters (such as repeats, rotation, offset, etc).
Texture format: use the dropdown to select the image format to use for saved textures - if any.
Click the Save as… button to export. A file picker will open, allowing you to select the destination folder and file name.
