Okay, okay let's see! I've had similar problems my self and some I've solved and others not. 1. When I copied the cloth physics while saving to .nif in OS, I notice I should only save physics form one piece on the lower body. So if I had a dress under a coat, I would only save the coats physics and not the dress too. This would in game still move both pieces individually even tho they where at different angles. Thus solving my problem of the coat going static. 2. The alpha channel will only show in game, if you in the .nif file inserted a NiAlphaProperty tab to the BSSubIndexTriShape of the outfit part with a alpha transparency enabled texture. And because I don't remember that gibberish by heart yet, I always use this guide: "Adding Transparency to Item (Tutorial) by Cat_Woman1989" 3. As far as I know, you need to either copy another items weights in OS or use a 3D program to "weight paint" new weighting that glue the pieces to a part of the mesh or skeleton. These are things that are too advanced for me still. So I haven't learned how to do it yet. 4. To make a body not clip through clothing that are in a solid fabric, you use Zap sliders to cut away parts of the mesh. That means you don't have to use alpha transparency in the texture also. The texture doesn't show as long as there isn't any mesh. I learned how from this tutorial: "Zap Slider Setup by Brain Poof". You also have to remember to set your body as reference, and then save the reference body in the .nif. I think that needs to be done cuz it will tick body slot boxes in the outfit, so that the game will recognize that there's already a body in the outfit (that you moded), if these boxes aren't ticked then the game will add the default body under the outfit. You can see these slot boxes in FO4edit, I don't remember if it's on the ARMOR, ARMOR addon or the ARMA tab. But you can edit the slots there, so that the game for example recognize your outfit to be a thin under layer like the Vault Suit. That will let you stack things like armor on top of it! :D I hope this helped with some of the problems! And you and anyone else is welcomed to ask stuff on my tumbler. I'm way more active there so it's a quicker way to get an answer, still ok to PM me here too. But since I just started modding I'm no expert. And if someone read all this and knows more feel free to correct me or add to this :tongue: //Angie My Tumblr ask box and message function is open ^__^
