How to use the map-viewer and what to do with it.
What does the map-viewer do?
It allows you to quite literally view the map. But what it also does it enable you to "overlay" box-size and tolerance on it to see how they effect the explorer and how he will behave.
When do you use it?
When you encounter a stuck or bad explorer behavior, such as the Jo-Jo effect bouncing forth and back between to points until timeout is reached.
Were do I find the map-viewer?
It is build into demonbuddy. "Info dumping" tab -> Map Viewer [Nice little button on the right side of the DB window]
Note: You must stop DB first before you can use the Map Viewer it will not work otherwise!
Workflow
You encounter a Stuck, you stop DB you open the "map viewer" and maximize the window adjust what you see so its nice and centered and you can see the entire map somewhat decent. Now on the bottom left side there are several options and value fields. This is were the fun starts.
First of ENABLE "Render Explore Nodes"
And you will see something akin to this
Now what you see here is already optimized basically when you experience a stuck play around with box-size and tolerance to make it mash as well as possible over the map without to many box's to explore and try to have the box's dot not outside the accessible map once your arrangement looks somewhat okay you start cutting down on redundant explore nodes by increasing and decreasing the tolerance. Make sure to never enter box-size 1-4 at any given point in time the map viewer will cash taking DB with it and in the worst case leaving some worker threads still alive in your ram causing issues.
Once you are done you update your profile go back to the start of the level / Rift restart db and let it run again to see if your explorer values are solid or not if they aren't back to the map viewer.. this takes time and because maps are dynamic there is no certainty that the values you found for one version will work for all of em but in most cases it should be fine because maps of the "kind" tend to be similar. The screen-shot I used is pretty much what an ideal state looks like no wasted movement no explore nodes outside the accessible area.
