I am curious and quite sure there is a way to do this. I'm trying to load a skin file in Simpe, find the code used for determining the genetic skin of a sim. I would like to then, pull up the sim in Simpe and change their skin manually. I thought it was the creator code for the skin, but it appears to not be the case. Does anyone have any information to share that may be of help?

Sorry. PM'd you back this morning. I will look into this asap. Thanks for letting me know.
Update: Found correct mesh and included link to my site for download. Sorry for the inconvenience.

Here you go... http://www.simfileshare.net/download/2540306/
You'll find recolors of this mesh here: https://simsdogpound.dreamwidth.org/

Gknee's site is missing the mesh (I am quite sure she edited with morph's) for Gothplague's jeans with sneakers. Should be the mesh titled MESH_gothplague_warlokk_tfBody_RIO_BaggyPants with "alteredbygknee" or "morphsaddedbygknee" at the end and the same for Ren. Any assistance would be greatly appreciated.

Montoto was the original creator of the Bear bodybuilder bodyshape. I did some recolors of the suit mesh to use for the Huge Bodybuilder shape and I believe Miros @ Wooden Simoleon had all the meshes saved on the her site but, now the site appears to be gone (a huge loss to the sims community by the way). The incredible JulieJ has some stuff here: https://juliejsimsstuff.wordpress.com/category/sims-2-male-clothing/sims-2-bearbb/. Unsure of anyone else that may be of help, sorry.
UPDATE: Miros is rebuilding here : http://www.woodensimolean.com/

First, I would try deleting all the phones on the lot. Second, try downloading FFS lot debugger from here: http://www.moreawesomethanyou.com/smf/index.php?topic=72.0. Third, examine what custom content you may have on the lot because something may be corrupted and a process of elimination is warranted. Otherwise you will need to move the sim to the bin and on to a different lot and delete the old lot. Hope this helps. Happy simming.

That's what I thought. It appears I have a crap load of work to do now (crap). Everyone might want to re-download my stuff when I'm done, though. A huge thanks to the both of you for your help and assistance.

AH HA! Two of the the smartest people I know still into the game (and the most helpful). Ok, to dumb this down, I can change any custom outfit (mesh and texture) in my downloads (not just the saved sims file) to show up for Y/A, Adults and Elders by changing the value to 58? By doing this, won't change how much memory the game uses, right? However, it would if I created (cloned) outfits through bodyshop using individual values, correct?

This is directed at all those who are smarter than I (and the list seams to grow with each passing day). I have read several tutorials on changing the age value for clothing outfits through the use of Simpe and have some unanswered questions that I need help with. First; It is my understanding that prior to changing the file you must first clone the outfit through bodyshop. Why can't the value be changed of the original file? Second; It is my understanding that if you change the age value to 0x00000058 it enables the outfit for all 3 (y/a, af, ef) or am I mistaken?

Very nice work. I tried logging into your site and received notification for wrong password, when requesting a new password, I get a notification the captcha I entered is wrong. 

When ever I can make you happy, it makes me happy. Especially since, being from California, Ive been dressing like this for the last 25 years. lol.

TheRaven is soooo awesome. Couldn't have done it without her help. They turned out really good (pats self on back).

This is what you helped get done....

Raven you are totally awesome for doing this. I can't thank you enough. It's very generous of you to give of your time and knowledge for someone you don't know. Thank you.

Raven, here is Vanity's original txt http://www.simfileshare.net/download/1802767/ . I tried to black out that part and wound up with a brown block. I was hoping to include a texture of a string tie or low profile slip D-ring tie belt. "I was hoping".
