Trees disappearing and creating a custom city

[DagelijksGamer]

Hi all

I'm creating a 1:1 map of PEI in Canada
Canada has a lot of trees, but sometimes when I turn my camera, a whole bunch of trees just disappear. They do come back, but only if I move or click on them.

Each of those blue dots is a spruce tree, just like the ones that you can see.

I obviously need to make custom cities as well. I created a .sii file in the def/city, I also added it to the city.sii. I deleted the default cities in these because I don't need them anyway. When I add a city in the editor, all the default cities show up, but not the ones I made. I created a country as well. Don't know if that works.

All help is appreciated

Regards

Can't you just generate the trees from the road nodes? It seems that you want to tackle this the hard way, as you seem to have a gazillion objects there...

It's likely that you are pushing the game engine to the limits by placing tree models like that.
Trees should not be placed like that (only in rare conditions). The trees should be generated from the road or terrain (vegetation settings)
