How to know building light time ?

Bonjour everyone !

I have been a UDK user for quite some time and in UE4 :
I can’t find the building time report when building lights…
UDK had a very detailed rendering window, with a lot of info regarding the different state of the rendering process (Building and sorting, photon emitting… etc…)
.
But more importantly long did the render took !
I can’t find that info !
.
Yes, there is a small Lighting result, in the message log window but it’s only errors and notes. Nothing about time.
I looked everywhere, and inside the files to look for updated files when the rendering is finished, I can only find file modified before the render is started.

I used to have several days rendering on UDK (I am doing specific things) and now I can’t estimate that when I go to bed and let my computer building lights. This is very important.
I can’t tell if it took 1 hour or 7 !

If there is a way do have detailed info when building, I’ll be glad to know that too (back to UDK style rendering)
.
Thank you for your insights !

Swarm starts up as it used to do every time you build the lights. It is minimized right next to the clock on the taskbar. Open it and you’ll see all the information you need.

Good to know that the swarm is clickable and expendable :slight_smile:
.
But what about after… when the rending is done ? where do I get the rendering infos ?
Ok got it : OUTPUT LOG…
(>window>Output log)

Thank you for your quick reply Jacky !

thank you !
