Flesh Effect Controller

This is an entity that helps you utilize the flesh interior effect on your models (if they have them).
You can spawn it through the spawnmenu, from the 'Engine Entities' category.
This does not automatically make every model have an interior, the purpose of this is only controlling the effect.

Pretty much anything you want. You could certainly use it for making screenshots, movies, etc. Also keep in mind this can be used for other things, such as weapons, vehicles, whatever you can think of.

It spawns the 'point_flesh_effect_target' entity which defines the effect and parents it to this controller entity. You can edit this entity by opening your Context menu, right clicking the entity and selecting Edit. Currently you can only change the radius, as the engine entity does not have any other settings. You can also turn the effect on and off (makes the radius 0), and enable/disable the sphere visualization of the effect radius.

Models will only get affected by 4 flesh controllers at the same time. This means you cannot riddle your model with holes, as any other spawned controllers will simply not affect your models, unless one of the previous controllers are deleted. This is a limit in engine, which might or might not get changed in the future.

Note: The only model that this works on by default is the HL2:EP2 Alyx interior model. In order to use it on other models, their materials need to be set up properly. How to set up your materials to use the flesh interior effect

Note 2: I use custom textures for my Alyx, so your Alyx will look a bit different than the one in the picture.
