Desperately seeking advice or help.
@BoilingOil, it depends on how you move the mesh. If you only move it in Milkshape? Then no. If you move it with the CRES, however - then yes. That's really the best thing to do in a case like this, rather than remeshing. Even if you export in UniMesh format (which you most likely can't, because Milkshape will go "OMG too many morphs are you crazy I can't read this I'm gonna explode waaaaaaah!" ) and retain the morphs, the Sim animations will no longer line up with the covers, since the the slot the Sim snaps into hasn't moved, only the mesh has. But if you move it with the CRES instead, then you move the whole thing - the mesh, the slots, the works - so everything will still be in the right place in relation to each other.
@Michelle I can show you how to do that, if you'd like. It isn't as bad as it sounds, I promise, it's just a matter of changing one value for one joint and you're done.
If all you (general "you") want to do is move the mesh backwards/forwards/left/right, the best thing to do is not to touch the mesh at all, but ONLY move the CRES (or rather, a specific joint in the CRES, one that's parent joint to all the others; a fellow called root_trans, most like). Then you'll only have to change a single value, the Y translation for that particular joint (in SimPE, Y = depth and Z = height), and you're done. But if you move the mesh instead, then you'll have to move all the slots individually to get everything to line up properly (because if you move the parent-to-all joint then, you'll end up moving the mesh twice, and then things will still be out of sync), and that's a lot more work. Yes, the principle is the same - you change the Y translation - but why change four or more different values when you can change just one and be done with it?
@ BO baby, thank you, believe it or not I always learn something new reading your posts, so please don't ever "STFU".
@ Nix, "OMG too many morphs are you crazy I can't read this I'm gonna explode waaaaaaah!", I love it, that's about how my brain has reacted to reading your replies to BO. Then I read "I promise, it's just a matter of changing one value for one joint and you're done", I let out a huge sigh of relief and thought thank goodness because as my father says...I'm is as thick as 2 short planks, when it comes to stuff like that. . Your help would be great, thank you , just so you know I have zero experience or knowledge about slots or CRES.
(By which I actually meant to say: if your sims end up in the wrong place in relation to the object, maybe someone should check that when you moved the mesh, the slots were properly moved with it. )
I think you're selling yourself short here, you're NOT as thick as two planks! Meshing isn't something everybody can do. But we'll take this one step at the time, and I'll be holding your hand the entire way (and you may kick my shin if I'm going too fast or get too technical). I promise you, though, when we're done, you're going to look at me (well, at your screen) and go "that's all??"
Do you want to go through it here, or go to PM? I'm fine with either.
