Hi guys, probably a silly question, but I am new so be nice 

I am just adding lights to my first project and I wanted to understand how reflection probes should be used.

A video I watched seemed to suggest that you need one directly under every light source in your map; is this correct? If not can someone please explain how and when/where they should be used?

Many thanks.

From what I have heard is that you need to use atleast one in every room you enter. If you want to know you need more just compile the map and see if you have red reflections.

I’m pretty sure you only have to use one (might be wrong though) but I add a reflection probe underneath every light just out of habit.

Make a room(room 1)
Put the xmodel " dest_berlin_barmirror " on each wall and the floor/ceiling.
Put the xmodel "sundirection_arrow" in the middle of the room.
Put a reflection_probe in the middle of the room below the "sun_direction_arrow".
Compile and look at the reflections.
If you had another room (room 2) with mirrors but without a reflection_probe you would still see the sundirection_arrow(from room 1) in the mirrors until you add a probe.
It applies to all reflective (specular) surfaces in the area.
Each probe automatically adds 1 image your map. They are 6 small images combined into 1 strip.
Dont add too many probes and lights until your map is near completion because it makes compiling slower.

Thanks for the explanation and help guys.

Funnily enough upon compiling my map this morning I got these 3 errors (which I haven't seen before).

WARNING: NEGOTIATION node at (-192.000000 474.000000 40.000000) overlaps other nodes
WARNING: NEGOTIATION node at (-218.000000 184.000000 40.000000) overlaps other nodes
WARNING: NEGOTIATION node at (218.000000 184.000000 40.000000) overlaps other nodes

Would that be anything to do with reflection probes overlapping, or is this something unrelated? I have a few path nodes which would be my second guess.

 This would probably have something to do with your traverses and path nodes overlapping indeed. Take a look at the position mentioned in the error (you can go to a specific position in radiant by one of the menu buttons in the top) and check which two nodes overlap. If it overlaps, move the path node a little bit.

(It could be that the traverse nodes are filtered away, causing you to not see the overlap. Check your filter settings in Radiant.

That was indeed the error, thanks for helping Lukkie.

For anyone reading this in the future, I had to go to the following in Radiant: Misc -> go to specific point -> paste in co-ordinates, then simply move the pathnodes a little as Lukkie suggested.
