Tested again....not working, don´t know what i´m doing different.
I tested it with 1.1.3....it worked, but this was few days ago and quality was really bad.
....or maybe now it doesnt work, i could test it again later....at moment i render 833 grids (with bing).
p.s. what i know, i had to lower the zoom level.
I tested all (with Aeroscenery newest Beta) and ArcGIS works, but quality is bad.
Google and Bing are much better, but i use Bing, because of the watermarks at Google.
