I'am still speechless about this new masterpiece. First Dubai by Martin and now your Montréal. What a great winter for flightsimming.

I'm still exploring all the small details.

But like the thread title suggests I have a problem with the autogenplacement on the photolayer. I can enjoy your handplaced autogen west of the airport, but the eastside is virtually empty. The autogenslider is full right.
I'installed Montréal with the default runway lights option enabled and replaced the Trench_Transp.bgl with your attached file.
Other addons in use: UT Canada & Alaska enhanced with Greater Toronto by Flight Ontario. I already tried to disable all other addons with no success. With the stock airport I get full autogen surrounding the whole airport.
Once again thank you for this otherwise fantastic scenery and sorry for my rusty English.
