I created an iron grate that will be frobable, and just like Wiki says, the frob box shape is the shape of my model. The problem is that it will be pretty hard for the players to highlight it, because of the distance between the bars. Basically it looks like this:
Adjusting frob box size doesn't help much in this case. I've tried other options like frob_peer, which works as intended, but the main problem is that even if I use a brush or model to propagate frob to my grate, it still needs to be solid for the frob raytrace to detect it. Materials like nodraw, clip or playerclip don't work, and that grate looks like it should let players shoot and throw stuff through it. I think I had similar problem while playing Biker's WIP, while with frobing an iron gate, so this is a common problem with more complex interactive models.
Am I missing something or it seems like we need some sort of special non-solid material like nodraw that will let everything through but collide with frob detection?
