texture problem (going over the whole body) I followed a tutorial for the sims 3 to the sims 4 accessory conversion here, and everything was fine, until I had to add the texture on sims 4 studio.
The object was converted with the protect paint, rigs and everything, still, when I put the 'diffuse' texture on the sims 4 studio, it seems to overline the object itself and go on the whole body.
I thought this could be thanks to something I didn't do right in blender, so I figure it wouldn't hurt asking here.
I'm attaching via mediafire - the blender files and the diffuse and spec maps in case anyone wants to have a look here.
I think you problem is the UV, your Main character is using all the UV layout and your spider is using all the UV Layout too, once you export both as a single object your are getting only one UV Layout for both objects, you need to arrange your UV's before you move frome Blender

Hope that helps

Good Luck
