Hi Rich even if you lay a line of light players will still suffer from LOS if thats enforced on the page (Unless you mark it with all players control and also give it vision) alternatively you could use the script here <a href="https://app.roll20.net/forum/post/4428847/script-light-crumb-trail-to-let-players-see-where-theyve-been-with-dynamic-lighting-on" rel="nofollow">https://app.roll20.net/forum/post/4428847/script-light-crumb-trail-to-let-players-see-where-theyve-been-with-dynamic-lighting-on</a> , although I have not used it myself it sounds like the sort of thing to fix this issue.
