You can find the Photo Studio templates for various paintings if you search for them. Here are a few links. There are others.

These should be very simple for you to learn how to do yourself, assuming you have SimPE's Photo Studio.

There is a good tutorial on using Photo Studio by Caitlin at https://theunofficialbbs.proboards.com/thread/123/recolouring-paintings-using-photo-studio

The only HBB bottom-only meshes by montoto_sk which I have are these (both from January 2008):

I knew of Dummy Thicc already. I haven't looked for new bodyshapes and neither new trans nor fat shapes interest me since I already have more than 40 different bodyshapes in my game already.

The main issue I have with most new bodyshapes is that they typically don't have enough varying Sims2 meshes and shoe options to round out a complete good wardrobe for acceptable use in my game. A lot of new creations are also 4to2 conversions which don't use "standard" TS2 mappings for their textures which makes recoloring and converting older TS2 clothing to those meshes extremely tedious and time-consuming.

I'm not familiar with that one at all and I thought I'd heard of most body shapes.

EDIT: I saw the links you had at ISA. But I don't have any of those. Sorry.

Very nice Julie!

There's also a skintone in the PunkJunkie link at the bottom of this post at GOS.

Teresa bodyshape was created by PierreNC at BAS. In my signature line there is a link to "HobbesED's Conversions and Creations", then within that is a link to "Z-Other Creators files", then "PierreNC", then "Teresa files". That link contains everything that was in Pierre's section at BAS.

I believe it has at least one skintone, all the showerproof meshes for Teresa Queen (adult) and Teresa Princess (teen) as well as several different clothing meshes and outfits including those you have pictured.

Those hairs look nice, Lizzy. THANKS!

Very nice Lizzy! Thank you!

Very nice Julie!

It's pretty SIM-ple. :-)

Open the skinfile with SimPE.
Click the Skin Tone XML entry in the Resource Tree.
Click the entry (Pale, Light, Medium, Dark, etc) that then shows in the Resource List.
The skintone code is located in the Family string in the Plugin View not the Creator string.

Chris is active at MTS2. While they don't have his adult mods there, you could try sending him a PM and ask if they are available anywhere.

Looking good Julie! The recolored masks should come in handy for stories about these crazy times.

Awesome! In the zip files, the BAS.text file is the text of the post when it was originally posted on BAS (BackAlleySims) before the site when away. Some downloads contain the required mesh, some do not. For the downloads without the meshes, I believe I added all of them in the separate Clothing Meshes download. If you find you are missing a mesh after that, let me know and I'll search it out and make it available.

One creator I left out is JulieJ. She is still active and her current things may be found here. http://juliejsimsstuff.wordpress.com/
