dynamic lighting no longer working on any map, any campaign

I cant figure out why dynamic lighting isnt working.  i have created new maps, gone back to old ones, etc.  multiple campaigns, all the same - its just a bright screen as if it is daylight. i seem to still be a paid member so i am at a loss.  I have rebooted.  this is the first time ive used roll20 (chrome) since the win10 update yesterday though, but a map we were in the middle of friday stopped working.  i created a new map, nada.  went back to an older campaign, its not working there either! help?

Hi Matthew, please could you supply a screen shot of the page settings for one of the maps you are expecting to see the lighting working correctly. A potential issue could be the use of the 'global illumination'. Another way to test it (as a DM sees all!!!) is to drop a token onto the map with their sight set up and use ctrl+l (cmd+l for mac users) with them selected to see their that tokens eyes, this should give you a good appreciation for if the set up is working correctly. If you haven't seen it yet, the  wiki entry on  dynamic lighting is super useful. Since you indicate that this seems to have occurred suddenly and that it was working previously I'd also encourage following the troubleshooting steps: Could you please carefully work through the first three steps of our guide to Solving Technical Issues ? 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!

thanks for the quick reply.  ive been using dynamic lighting for ages and am not new to it.  and like i said, its no longer working on older maps, not just the new one i tried creating tonight.  Ctrl+L sadly reveals a fully illuminated screen Its taking 5+ minutes to load a small page.  Again, no idea if it is at my end or yours (thats what im trying to trouble shoot) but it shouldnt take minutes to load a small page heres the dyn layer heres an orc chef, with light, and sight, ctrl L to see what he sees, no effect

Son of a gun, it works in Mozilla just fine.  I havent touched Chrome in ages.  Epic debug session coming on.   Sorry gang, i should have tried mozilla sooner

Interesting, are you the creator of this game or a co-GM? If you are the creator then please supply a console log as per my previous post as this will help the dev team identify and potential issue. Also, does this behaviour persist in firefox? [edit] you beat me to it... it could be a beta version of chrome that has self-updated causing your problem in which case it will likely work again sometime soon once the kinks are worked out, until then at least you have the firefox workaround :)

i fixed it, and it was disturbingly arcane.  It had nothing to do with extensions. I had to go into chrome://flags/ and turn on WebGL Draft Extensions and also WebGL 2.0 Prototype (just turning on the first did not fix it, it required the 2.0 flag as well)

Glad you got it sorted and thanks for sharing the steps required, hopefully it will help others who have the same issue in future. Happy rolling :)
