Is there any reason why AA stops working when Unity is run from a server within a website?
It works fine locally when exported for web.
Edit: seems a player issue - see below
This seems to be a player bug - I have not time to build an example right now - but if we resize unity to 1x1 at start to hide it and then enlarge it again there is no anti-aliasing anymore.
If we just start fullsize with no hiding it is fine.
Have you double checked your quality settings in the editor?
Like I said - it works fine when run fullsize, but if you resize the unityObject to 1x1 and then enlarge again the problem occurs (no anti-aliasing). If I have time around work I will recreate in a test project.
sounds more like a consequence of the resize, potentially the graphics driver stops the AA because there aren’t enough pixels on the 3D context anymore to alias anything
