Just about to upload my new asset up to the store; but I have just a few questions about structure and the like. I have 2 models (low poly and a high poly model of the same thing) Each model has 30 different skins. These skins include a specular map set in the alpha channel. Question 1: Should I make a different prefab for every one of the 30 materials? Or just one asset and let the user assign the material that they want? Question 2: The only two types of files I found that support the alpha channel (For the specular maps) are .psd and .tga Which do you as a user prefer? .psd seems to save more space than the .tga; and that is what I saved my color maps as, but just need to make sure this is appropriate. Question 3: I read all of the documentation on uploaded assets, but there was a section that said include a .txt file with an explanation of how to use the asset; then it said delete everything from the folder that isn't part of the asset including any text files. So I am confused, if I want to give a .txt or blender file with the assets how do I do this? Thanks all.
