This page is a much more NSFW area containing ERP addons to avatars. This knowledge is in demand for some reason.

Nude Toggles

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.

Look up how to do toggles in the Toggles section on Avatar_Hypertutorial. The ANY toggle is what I use most for outfit changes, it's easy enough to understand and use.

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.

In the video below I add a vagina, paizuri, right hand, and mouth orifice. Tweaking needed for some of them (the pinch point is right at the centre of the circle so you want that slightly inside your mesh in most cases to hide it). I do something special with the mouth orifice that should be paid attention to and toggles are handled by vrcfury (but you can do them manually if you want).

OSC Goes Brr

Tl;dr:

add SPS to both top and bottom. (just like in this tutorial)
install and run intiface, and then link your toy (Use a bluetooth dongle with a antennae for best results; the lovense dongle sucks ass): https://intiface.com/central/
Run OSC goes brr https://osc.toys/download
"It just works"!

Penetrators

Penetrators are much more work. If you have a prefab you might be able to skip some of these steps but here we will do cock attachment.

First find a cock. Ask around but I'm using https://humiliationvr.gumroad.com/l/humi-dick . Bad news is I'll be stripping 90% of the features - as this allows the tutorial to work with basically any cock-object rather than this specific one. Keeping features probably easier since you can just use the prefab; but this is a tutorial not a 'use the prefab'-orial. I'll basically just be pulling out the mesh and textures. (That said you could totally backport stuff you make into the prefab)

Colour Matching

Commonly asked but assuming you have a dick to work from; blender and photoshop are a good pair to match the body to the dick. In the video below I match the skin tones of the dick to the body, and then blend the body to the dick for a reasonably seamless looking texture. When in pure flat shading it looks pretty good.

Normals Matching

The images speak for themselves. Even with perfect color matching you will get seam problems when the mesh isn't a smooth curve to the body; matcaps make it obvious. Faces on mesh can pretend to be facing a different way for shading effects and by smoothing these 'normals' between the hard mesh cutoffs you can smooth out the angles in the mesh to make it look attached.. without actually attaching it.

Adding SPS

This is it. Now with SPS this is rediculously easy, it barely needs a video.

Things to note:

You can add a seperate toggle for the SPS functionality so you can have a frotting ring on the end of your dick and have it actually work
this should work with sockets with osc interactivity and animations and all that crazy fun stuff that people haven't explored much yet
PP needs to be on the UNITY armature, usually the hips. ( a dildo would need to go on a hand for example) Unpack your prefab.
NOTE: Interactions with pumkins can be flakey when you attach the dick in blender. See notes below in iteration problems for details. However; the reason I attach in blender is because the matching was done in blender and moving stuff around in the unity editor makes me want to die.

Common Problems

Not setting anchor override for the mesh
Not setting the mesh to be a child of the hips (or other bone)

Iteration Problems

Pumkins tools can't copy VRCfury components or get the mesh right if it's supposed to be a moved part of the prefab. If you've attached a PP in blender and are doing iterations you'll need to do the following:

Fresh import FBX, apply preset to the import
Use pumkin tools to copy over everything
Move the 'blender attached' PP to the Hips like in the above PP guide, then move the Haptic Plug component from the 'phantom copy' to the blender pp.
Fix the material, anchor for the blender pp
For VRCfury toggles, copy the component from the old version

It's a bit lengthy and eats into the advantages of using vrcfury and pumkins tools but I had a problem with SPS/vrcfury and pumkins and it took me ages to debug.
