Naked toggles are pretty easy as it's a standard toggle that is covered in the previous. However, erp has some specific things that are often added to avatars for.

DPS / TPS / SPS

DPS, TPS and SPS are cross compatible penetrator in hole technology on the shader itself where the inserting object homes in on orifices for more immersive sexo. DPS is the oldest, TPS is something that comes with Poiyomi shader, and SPS is a fairly new system that gets applied at runtime which does the same thing but theoretically works on any existing shader.

SPS has way more features and is easier to setup so I will be using SPS for the tutorial. A DPS guide may get created but I'm an SPS convert.
