<div dir="ltr"><div>Hi All,</div><div><br></div><div>I'm trying to use a Special-Event PDF as a transparent layer overlay for an existing OSM Tile Source. I've already used MapTiler to split the PDF into the appropriate tiles and can export them as a TMS directory structure or as a mbtiles file. </div><div><br></div><div>If I use a tile server to host the Special-Event tiles and use a combined cache to provide a layer to my web browser (via WMTS), the Special-Event tiles are transparent and I can see all the way through to the underlying OSM tiles.</div><div><br></div><div>Config: <a href="https://gist.github.com/ampledata/c60602300ea02adb744b216a0b21439a">https://gist.github.com/ampledata/c60602300ea02adb744b216a0b21439a</a></div><div><br></div><div>If I use a local TMS file cache to host the Special-Event tiles and use a combined cache to provide a layer to my web browser (via WMTS), I can ONLY see the Special-Event tiles and I cannot see the underlying OSM tiles:</div><div><br></div><div>Config: <a href="https://gist.github.com/ampledata/e81f8848d92621774e0cb2d3973edb64">https://gist.github.com/ampledata/e81f8848d92621774e0cb2d3973edb64</a></div><div><br></div><div>I'd prefer using a local TMS file cache to host the Special-Event tiles, and have them be transparent on top of the externally hosted OSM tiles.
