What does collision_shell = "V_lom.edm" mean?

 

I mean what is special about V_lom.edm compared to other collision shellls. Is it an actual edm or is the name just used as a shortcut for a built-in feature.

 

I ask this because I noticed that V_lom is being used for some fairly different types of objects. Different sizes too.

OK I think I have a guess. LOM was an old file format and V_LOM is a shortcut that says to use the simple hitbox that is defined inside the converted model.

 

Is that close?

Might as well tell the whole story. I am looking for reasons why hit detection seems buggy at times in DCS but only for certain projectiles. My present theory is that some lod settings are interacting negatively with this v_lom thing.

 

Wish I could view the collision shells.

I had to use standalone version of modelviewer to see collision models.

 

It is quite interesting.

 

Some of the AI aircraft have amazing collision models, others are fairly simple.

 

Half the CA vehicles have collision regions for turret, gun and chassis. Not supported in CA code as far as I know.

 

M-1 tank has edm collision model that is more detailed then the rest

  • turret has top, left, right, back, front regions
  • chassis has top left, right, back,front regions
  • wheels, and tracks also have own region

Not supported in CA code as far as I know.

 

Ships have a detailed edm colllision model in and it is enabled. Perhaps there is a way to trick the engine to turn it on for tanks. The M-1 land ship
