I have a directory with .terrain files in subdirectories:

Now trying to configure Nginx for this folder:

server {
        listen       *:8087;
        server_name  localhost;
        
        location ~* ^/DEM_B1_Area/.*.(terrain)$ {
            add_header Content-Encoding gzip;
            root "D:/dev/nginx-1.12.1/www";
        }

        #location /DEM_B1_Area/ {
        #   root "D:/dev/nginx-1.12.1/www";
        #   allow all;
        #}
    }

And in url returns 404.

http://localhost:8087/DEM_B1_Area/0/0/0.terrain

I’m not very familiar with Nginx. What can i miss here?
