Several type of collisions exists? How to change/adjust?

[Otakadelic]

I have a question about collision on DOA5LR.

 

This picture is my WIP Petgirl Kasumi with tail plug from asshole. It moves smoothly like soft rope however going inside of Kasumi's body.

Spoiler

 

But her hair moves naturally and not go inside of her body. 

 

Another picture is yet another WIP one of my Kasumi Pantyless Pack.

Spoiler

 

The skirt(well, sort of) and side ropes never go inside of her body. Perfect move in this case.

 

The last pic is Honoka with unmodified costume.

Spoiler

 

One of her white balls attached with her wrist clearly go inside of her body, not perfect move like her hair.

 

So, looks like three kind of behaviors of collision exist in this game:

 

1. Hair versus Body.

2. Costume(mainly skirt) versus Body.

3. Accessories versus Body.

 

Some mods works flawlessly while some accessories of official costume goes wrong like this Honoka one.

 

So my question is:

- How can I avoid attached accessories go inside of character's body?

Which leads this question:

- How can I control collision (or change of type of collisions)?
