How do I lighten pathfinding ?

Hi,

I use a single object for all the elements of decor, changing only the "frame animated" to differentiate them. It works perfectly.

The problem is that some among these objects should not interfere pathfinding. And I can not exclude when I use "Add Pathfinding obstacle" they are all selected. Is there a way to select them otherwise?

The problem being that the number of items is High and when the pathfinding is calculated I have a little lag moving my character.

thank you in advance and sorry for my bad english

How about this..

If pathfinging obstacles (wall)

only one real obstacle just many instances of it.

where wall is (solid) and is set (invisible)

instead of trying to create one object and trying to set each instance different.

Why not create 2 objects instead for the elements of decor that affect pathfinding and for others that don't.
