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 general coom tech

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.

Penetrator Systems (PS) all work in the same way: Dicks are marked as penetrators or plugs, and holes are orifices or sockets. Dick goes into hole.

Orifices

Orifices for recieving penetrators are easy to add. Choose type of orifice you want, move orifice icon into place, line up insertion arrow with where you want, and make a toggle. RING orifices have the penetrator move through the point, and you want those on hands and external parts. HOLES disappear the penetrator shortly after they enter the point, and are more useful for internal parts where you want the penetrator to be buried as deep as you want.
