It may come to a point where I need to convert clothing from TS4 into my game so I want to know if there's any tutorials out there as looking on google gives me the other way around (i.e., TS2 to TS4). Do I actually need TS4 to be able to convert a mesh or will TSRW work? I do have Milkshape and I've fooled around in it for a while to get the hang of it in case anybody's wondering.

Take your pick

One tip - search for "4t2" instead of "TS4 to TS2". Often gives you better results

TSRw will not work other than for extracting TS3 clothes (I've had issues with it for TS4, though I'm not sure if it's been fixed since I last reinstalled), but Sims4Studio works very well. You may need to have TS3 and/or TS4 installed because of the skeletons, though I'm not entirely sure. It is possible you can make do with downloaded meshes for TS3. You do need Blender and Milkshape, and a few other programs (should be linked in at least one of the tuts)

I have noticed that the method used in the tutorials sometimes give rather mediocre bone assignments that may need fixing before the arms are rotated. Sometimes not a problem, other times it causes weirdness when the sim moves. Maybe I'm just too much of a perfectionist when it comes to bone assignments, so I sometimes do them manually (and rotate the arms directly in Blender before exporting, because the result turns out a bit better for poofier arms).

Thanks simmer22! I did go to the TSRW web page and it says it's been updated for sims 4 seasons so maybe I'm in luck, if not I'm gonna kick my past self in the leg for not getting TS4 for free . And yes I do have Blender but I didn't mess around in there too much, but I will definitely look at these videos this weekend!
