This is a version of the scaler I use for my main, but isolated to only affect the chest. Though designed with male model bodies in mind, this should work on any body so long as it has mune (breast) bones to scale and adjust. The position is edited a bit so they still sit up on the chest. Please feel free to adjust it to your liking! I just wanted to provide a basis for people looking to make a character with a smaller chest than what's available to them. "Make a new chest size" only applies if people upscale to it, after all!
There may be some warping of clothing meshes, broken seams in clothing, and weird weights. Sometimes I get a weird vertex that sticks out around where the bottom center of the ribcage would be - c'est la vie. I'm not sure how to fix it; I think it's a weighting issue. Who knows!
I also wouldn't recommend using this on an already flat / small chest unless you'd like for your breasts or pecs to go concave. Unless that's your bag - in which case, go for it!
How to use:
Copy the text below for your desired scaling and add to the C+ profile of your choice. You can use it alongside any other body or face scaling that you have as well!
