I can't seem to figure this out and don't know the right lingo. I have the textures and the mesh. What my problem is, is the fabric is the wrong scale. I don't meant the file sze or anything like that. Both the mesh and the texture are the same dimensions. Lets say it's a floral print. If I use it as is, there will be 1-3 huge flowers on the skirt, instead of being in scale and looking like a floral skirt would look in rl. How do I take this texture and change it to be the proper scale? I'm using gimp. Thanks in advance for the help
