- Before exporting your Blender models, its is recommended that you clean the buffers of any unneeded `Action`, `Material`, `Texture` or `UV Image`. This is a straight forward process that only takes a few minutes. Failure to do so can lead you into a morass of problems, like having more than one AnimControl, duplicate materials and textures, wasted space from worthless images, just to mention a few potential troubles.
- == Material, Texture, UV Image Buffers
- . Open the `UV Image Editor`, `Material Tab` or `Texture Tab`.
- . Select the btn:[Browse] button located next to the material, texture or UV Image name to load the item to be cleared.
- . While holding kbd:[Shift] down, click the btn:[X] button, also known as the btn:[Unlink datablock] button, located next to the loaded item. An item that is unlinked will show a `0` before it when viewed by selecting the btn:[Browse] button and will not be saved if you exit Blender.
- . Save your file.
- . From the `Info` header select `menu:File[Open Recent > Your Saved File]`, to close and re-open your file.
- The exception to this rule is the `Linked Action` buffer, for animations, located in the `Dope Sheet Editor`.
- == The Linked Action Buffer
- . In the `Dope Sheet Editor`, change the context to `Action Editor`.
- . Click the `Action to be linked` button and select the action you want cleared.
- . Deselect the btn:[F] button to prevent it from saving.
- . Change the editor type from `Dope Sheet` to `NLA Editor`. You will see the action listed.
- . Click the icon:angle-double-down[] button next to the action to push it into the stack.
- . Click the small start next to the track name.
- . With the mouse inside the `NLA Track List`, press kbd:[X] to delete both the track and strip.
- . Save your file.
- . From the `Info` header, select `menu:File[Open Recent > Your Saved File]`.
- . Save your file again.
- . From the `Info` header, select `menu:File[Open Recent > Your Saved File]` again.
- . Change back to the `Dope Sheet Editor`.
- . Click the btn:[Browse Action to be linked] button and you will see only the baked action remains and the buffer is now clear of unwanted actions. Select your action.
- . Save your file.
