Lighting problems

So I’m really new to Unity (especially to graphics) and I’m making a map.
It’s nothing fancy yet and only has some rivers and a small forest.

Now my problem is that since i added the small forest to the map, my cpu load goes to 100%.
Now i have a good cpu (intel i5 4690) so that’s not the problem.
I read on the forums that it has something to do with the lighting that has to be calculated.
It opens JobsProcess.exe 2 times and they are both at 45%.

Should i let this run or what should i do with it?
Because it gives me this green progess animation in my taskbar icon, but it doesn’t seem to go forward.

Hope you guys can explain this to me a little bit since i’m new to it.

Thank you!

That’s probably the Global Illumination being calculated. By default its set to calculate whenever a change is made.
Calculating GI for a huge forest will take lots of time. Just wait it out(When I did the same thing it took about 3 hours) or you can go into the lighting tab and turn off the continuous calculation of GI.

thank you for your fast reply.
Where can i find the lighting tab?(Sorry still learning everything)

Go up to “window” in the toolbar at the top. Find lighting and click it.
You can change a lot of settings here.
I forgot to mention that turning off Global Illumination completely will make everything not look very good.(In my opinion)

yes that worked great thank you!
