Vision and Camera Control
As title says, I got two questions regarding vision and camera.
1) I want to allow players to increase camera view higher than default value in Dota 2. Would it be as easy as adding one line to lua script, or do I need some special arrangement? Another thing I'd like to do is locking camera to certain location for the duration of spell. Couple months ago I saw some custom game with camera lock button so it seems doable, can't find it though.
2) I got some terrains going in my map, but terrain on flat ground doesn't seem to be obstructing vision. In this picture http://i.imgur.com/bEgK39i.jpg, you can see that the house on the left side of hero is not hindering vision at all. It is basically just a house model I imported with Skip block inside, so I guess there's more to creating terrain when it comes to sight. Do I need different kind of texture?
