Video Tutorial: Avoid Stretched or Squashed Images With Texture Aspect Ratios
In the below video we see a tutorial on how to avoid stretched or squashed images when uploading and applying them to prims in Second Life. The key is to use image texture aspect ratios. In the below video you see the asp0ect ratios for different types of items listed on the Second Life Wiki Texture Limits. You can then use that information with an aspect ratio calculator such as the Javascript continuum ratio calculator.
The tutorial shows how to change your image in Adobe Photoshop or another image editor in order to prepare it correctly. You must then save the .png, upload it, and ignore all the previous until the end result shows the correct proportions.
The image is applied to the profile and then to a 3d prim in Second Life. The video is in high definition and is over nine minutes long. Check it out below.
