2 mapping questions

[Grab]

Hey, I have 2 questions.

1. I made JKA version of "Eye to eye" map. This is small map where you duel with weapons only. To make players spawn with weapons I made trigger_always with map sized trigger that links to weapons. I feel like it's not good solution. Also on map start or on round restart you don't spawn with weapons, so you need to selfkill to get weapons and it is bad. Is there any possibility to make it better?

 

2. Is it possible to make some brushes/entities transparent for NPCs? I don't want some brushes/entities to block vision for NPCs.
