Texture Picker
This window is normally accessed via the Texture tab of the Edit window, but also from any location that allows textures to be selected.
The texture picker allows you to select a texture to apply to an object (among other things) - assuming the object is modifyable for you. If not, then you will not be able to do anything with this window.
The large square will display the current texture for the object. If the objects has multiples textures, then the box will display this (in text). This warns you so that you do not inadvertently change textures you did not intend to change.
Below this is the size of the currently displayed texture, in pixels.
The Default button will apply the standard plywood texture (shown in the image to the right).
The Blank button will apply a blank white texture.
Transparent applies the standard transparent (invisible) texture.
None Removes the texture entirely. This is not used on objects, but it is useful, for example, to remove a profile picture, or the image associated with a parcel.
Apply UUID Enter the UUID of a texture into the field and click Apply UUID to apply that texture to the object. When editing, this field will only display the UUID of textures which exist in your own inventory.
The Apply now checkbox will immediately apply any changed texture to the object, so that you may preview it.
On the right side are two radio buttons: Inventory and Local. These allow you to use textures from your inventory, or directly from your hard drive.
Inventory
The folder list shows your inventory folders, and the textures they contain. You can use this to select a new texture to apply. Another way of selecting a texture is to drag it from your inventory window into the large box at the top left.
A third way to select a texture is to use the dropper icon, which is below the large texture square. You can then click on any texture on any in-world object and, providing that you have that texture in your inventory, it will be used by the texture picker. This is a very handy and rapid way of selecting textures while building.
Once you have finished, Click Ok to apply any changes made, or Cancel to revert to the original texture.
Local
In this view, you can access a list of textures (images) that are on your hard drive. This allows you to preview how a texture will look, prior to uploading it. It is an alternative to using temporary uploads.
NOTE: An applied local texture will be visible only to you, and only until you relog. You can get around others not seeing local textures by uploading the image to a picture sharing site (eg, Dropbox, Photobucket, Flickr, Imgur, etc) and then using media on a prim to display it in-world. You can also work on beta grid, where uploads do not affect your SL L$ balance.
This view has a few buttons, and below that, a list of the textures you have already added.
- Add: this opens a file picker window, which you can use to select a new image from your hard drive, to add to the saved list. The texture selected is not automatically uploaded; it is merely referenced in the list below.
- Remove: deletes the currently selected texture from the list.
- Upload: uploads the currently selected texture to SL.
- Apply now: If you click on a texture in the list, you will instantly see it applied to the item that you are editing. Note again that this will be shown to you only.
Some use scripted systems to apply temp textures for testing, such as on various mesh body parts, but since a local texture doesn't shown in inventory, you can't get the UUID to add to the script. Solution: Surprisingly, llGetTexture can actually get a UUID for the local texture when it is applied to a prim, and llSetTexture can apply it.
