<p>Hi Nyall,</p>
<p>Thank you - this explains it. I wasn't aware that QGIS server uses an old map renderer. I did not even know that different map renderers exist. But this has nothing to do with the old vs. the new symbology - right? Because QGIS Server seems to work just fine with the new symbology and labeling.</p>
<p>So much work to do around QGIS 3.x / QGIS Server, etc. ... </p>
<p>Andreas</p>

<p dir="ltr">Hi Andreas,</p>
<p dir="ltr">Server doesn't have access to any of the map settings related variables, like the scale, rotation, extent, etc. (This is why 25d ordering is messed up in server).</p>
<p dir="ltr">Server needs to be ported away from the old map renderer before this can be fixed.</p>
