Hi,
When a light source on a map was selected it used to show the area illuminated with a ring
like this: 66943
I'm not seeing the area highlighted anymore: 66944
(in a clean 5e/core campaign with no extensions)
I'm wondering if I have missed a change or is this bug?
Any help here is appreciated

Some recent bug fixes to critical parts of the renderer introduced issues with the lighting ring. The lighting UI is being updated as part of an upcoming overhaul of the line-of-sight systems. Rather than risk re-introducing the critical bugs, the lighting ring has been disabled. It will be returning the new LOS system.

Hi,
Sounds good. Any idea if the update might include automation for low light vision as used in PF2E?

Vision types are handled by the individual rulesets. If you questions about low-light vision in PF2E, you'll probably want to ask over on the PF2E forums: https://www.fantasygrounds.com/forums/forumdisplay.php?105-Pathfinder-2E

This is the definition for PF2 low-light vision: https://2e.aonprd.com/Rules.aspx?ID=2411
Correct me if I'm wrong, but I don't believe there's anything that can be done in the PF2 ruleset to make dim light appear as normal light to creatures with low-light vision - this would have to be an application change, right?

I see. Yes, if the effect of low-light vision is to boost dim light to normal light then it would require a change on the client. I will add it to my notes for the LOS rewrite. I might be able to find a reasonable way to accommodate. If we assume that no light is zero, low light is 0.5 and bright light is 1, then low-light vision would boost those values to 0, 1, and 1? Is that correct?

Yes, that's correct.

That's true for PF2; but not for all instances of low-light vision (PF1/3.5E/D20M) define that vision as doubling (which is not something that Carl would be able to add easily, or even in a way that was performant).
