    • Verify that a subset of the texture appears on the surface
  • Change the Horizontal and Vertical Offset
    • Verify that the texture is offset on each face
  • Enable Horizontal and Vertical Flip
    • Verify that the texture flips on each surface
  • Change the Rotation value
    • Verify that the texture rotates correctly on each surface
  • Change the Repeats Per Meter and click on Apply
    • Verify that the Repeats per Face values change accordingly
    • Change the Repeats per Face back to 1.0 and verify that the Repeats Per Meter value changes
• b. Face Texture Test
  • Open up the Inventory : My Inventory : Textures folder (or filter your inventory for textures)
  • Drag test_256_256_alpha on to one of the faces on the box
    • Verify that the texture appears correctly and that you can see through it

  • Drag test_512_16 on to the same face and verify that it appears correctly
    • The image should appear blurry since it is being stretched across the surface
  • Resize the box to 2x2x2m and Set the Texture Mapping to Planar
    • Verify the texture repeats have increased on the box.
  • Change the Texture Mapping back to Default
  • Take the box created for the next test

6. Texture Priority

• Locate an object in the distance with an unloaded or blurry texture.
  • You may need to fly to a new area or log out / log in.
• Zoom in on the object so that the blurry texture is large and centered in your view.
  • The texture should quickly improve to the correct resolution, before other nearby textures do.

  • Click save
  • Verify the texture on the object still looks ok (not clamped).
  • Verify your avatar appears the same to another person as it does to you.
