Hi everyone, I've had a couple of problems porting a clothing mod from OLDRIM to SSE.

 

Here you have some images so that you understand better what happens.

As you can see the skirt are ultra-bug, is like an ubisoft work hahaha

 

I took this mod and passed the ".esp" for the CK and the meshes for the NIF Optimizer. The result is that of the images, it only happens with the skirt of that mod.

What did I do wrong? For mods with HDT, do you have to do an additional step? I clarify that I am totally new this and I understand little and nothing ^^

 

I thank you for your time and the help you can give me. A hug!

 

PD1: If you need any additional information please tell me and I will try to give them as soon as possible.

 

PD2: If something was not understood, tell me. I am using the google translator.
