If a texture is missing, open the template file for the skin you are replacing in SimPE.If you find a texture that doesn't belong, delete it.The number at the end indicates what default skin it replaces (light=1, normal=2, medium=3, dark=5, alien=5).

Compare the listing of textures to the list below and make certain that all the textures are present.Open the new package in SimPE, select 'Texture Image' in the resource treeand sort by 'type'.Be sure to name your package something that will be easy to identify later. Then click 'create default skin Override'. Set the 'Base Skin' to the one you want to replace and check the 'Override TXTR' box.

Select the skin you want, select the 'Operations' tab and find the 'Skintone Scanner' section.

Select the directory that contains the skin you want to make a default replacement version of and scan. The illustrations in this tutorial use version 0.52. If you are interested in creating your own default replacements from scratch, check out the MTS2 tutorial by WhoGivesADam, Changing Default Textures - Without editing Sims07.package. They can be found in the Default Replacement Skins section of this web site. I don't see the point in duplicating work, so this tutorial assumes that you are working from an existing default replacement skin package for reference instead of creating your own.
