TokenMod already supports UDL via some other properties. Here are the notes on the two updates: UDL Bight and Dim Light, and Nightvision: <a href="https://app.roll20.net/forum/permalink/8641944/" rel="nofollow">https://app.roll20.net/forum/permalink/8641944/</a> UDL Restricted Light and Vision, Nightvision Tint: <a href="https://app.roll20.net/forum/permalink/8984523/" rel="nofollow">https://app.roll20.net/forum/permalink/8984523/</a> I'm going to look into a compatibility setting where setting the LDL properties can automatically set the UDL ones as well or instead, but it's not risen too high in the todo list yet..
