Correctly rigged in blender, weird looking in world

[Lollina Carpaccio]

Hi! I'm moving my first steps on mesh clothing and rigging using avastar.

I've created the mesh and rigged it succesfully on blender using avastar and it shows just fine and rigged.

 

When I import it inworld though, this happens: (1) Firestorm-Releasex64 7.1.10.75913 - Lollina Carpaccio

 

I am very confused and couldn't find anything online about it. does someone know why this happens? I've previously rigged a tank top and everything went fine.

 

UPDATE: I've done this after changing the avatar pose to a A pose and set as rest pose. This because it feels easier in Marvelous Designer to work like that. If I keep the T pose and rig for it, the mesh preview is correct. How can I fix this?

As far as I could understand, Second Life expects imports of mesh in a T-pose. Therefore, before exporting the collada (DAE) you should rebind the armature to the T pose and that should fix the issues. I haven't tried yet but I thought I'd share.

So, i tried and it was true! At least was this time. i didnt rigg in a T-pose, so i did and fixed the issues. 
Thank you for the help!😊
