Is my map too large?

I seem to be getting lots of technical issues with my Tomb of Horrors map, possibly due to a too large map (?). Sometimes it works perfectly, sometimes only half the map tiles load properly, and sometimes the screen is just black or a textured grey. The map is 85x90 units, but I don't think that should be too large, am I wrong? Would be thankful if an admin could take a look and see if there is anything buggy going on... Quite often I get a message saying WebGL encountered a problem, and the Dynamic Lighting is often acting up (only showing chunks of the map, cutting of vision etc)

Sounds like the map may be too large, thats certainly around the upper limit. I'd recommend either: Split the map into sections over separate pages Halve the size of the map and set the units to be 0.5 so that your grid is half sized too Depending on the 'load' on the browser (DL, map elements etc) you can often see the browser timeouts with pages of that size and above. If you'd like a full 'diagnosis' please follow the below steps: Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome and Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable all add-ons/extensions and anti-virus programs. Step 3: Clear your cache If none of the above succeeds, please thoroughly work through Step 4 . (Don't forget the complete Console Log!) Thank you!
