Hello , I would like to be able to get a heatmap , where the npcs walk the most , and be able to send this data over the internet , is it possible ? if so how can I do it or where can I read about how to implement it ?

Ok but this is a paid system I want to know how to make it from scratch.
game Telemetry isn’t something you can learn from a Tutorial without any knowledge behind the fundamental basics of mathematical telemetry…
Thats one reason causing the lack of any useful tutorial about that topic…
In fact… There are nearly none plugins to handle that…
So i would search my way through bookstores and ebook Learning’s of Telemetric Topics…
Or… Safe some moneys and get an already existing plugin, that has your needed features…

I found this :
Its enough for my scope but I want to apply to npcs.
You can use nearly the same approach as shown in the video. When spawning your AI you can add them to an array. From this array you would get the location from each of the AIs and use it as DrawLocation (instead of always drawing). So you would just be painting points with low opacity in a fixed intervall using a timer. Over time you would get a heatmap showing the most frequenced locations of your AIs🙂

Thanks I will try first and probably come back when I get blocked!
And here I am … I followed the tutorial in all its parts but doesn’t work …
I tried first in first person , as my setup is 1st person then the only changes I did are :
1 Used an uneven shape instead of a squared platform as base mesh and I did change the entry for npcs instead than player reference…
what can be wrong?
the mesh 
Splat Material
Heatmap material
