how to take proper thumbnail photos

I've been using the photo room light map, but I cant figure out how to make proper thumbnails, and how to make the thumbnails appear to
example:

 

Thumbnails App. No reflections. Make sure it's only your mod so it doesn't take a year.

 

its on the black map

 

I believe there is a checkbox under advanced settings in the app that says something like “stay on current map,” which you can use to take screenshots on the white showroom map mod. The thumbnails will get saved to the vehicles folder in documents/beamng.drive though, so you’ll want to move them to the actual mod file before uploading your mod. Hopefully that helped! Let me know if you have any more questions! (^^)

 

Thanks (^ヮ^) although it bothers me that the screen shrinks itself
