Global changes to existing token settings?

Hi there! I'm running Roll20 for the first time, with The Sunless Citadel . We started with the new Dynamic Lighting Setting but glitches had me switch to Legacy lighting. Unfortunately, all monster tokens seem to emit 60' of bright light now and I'd like to know if there is a way to change parameters for all existing tokens at the same time (e.g. to make none emit light, have sight etc.). I could manually make PC tokens emit light again, for instance, but fixing every monster token individually is out of the question. Best wishes Martin

It seems there is an API script which satisfies my needs. However, I only have a Plus account. I only need to do this once for the module and we'll be playing many weeks or months. Hence my new question: Can I upgrade to Pro, run the script, pay $5 extra, and DOWNGRADE TO PLUS again?

Have you tried changing the token defaults in game settings? That should do the trick on any new tokens you drag from the compendium. If they're already on the canvas, I don't think settings will help. AFAIK if you upgrade, then downgrade your subscription, nothing will be undone or deleted from your games - it will just remove access from using those features any more. For example if you go Plus->Free->Plus, your dynamic lighting layers will still be there, even though you can't see or use them while you're on a Free account. How many monsters are you talking about? Monster types that is, not number of tokens.

Thank you for your answer. My estimate is that there are about two dozens different types (kobold, kobold bounder, various named kobolds etc. etc.). Why? (The tokens have been pre-placed on two maps in great numbers. However, not all of them seem to be emitting light (Good!) but many seem to have sight (Bad for performance and I'm unable to see this without clicking on them), so it seems there are either a lot of clicks or a $5 expense ahead of me. Unless you have an idea to speed up the process, perhaps?

Yes, you can buy up your subscription for one month then return to Plus without losing anything. There are scripts that can help. I asked a very kindly Scriptomancer to write a script that would remove all sight from all tokens everywhere on a page or in the game at one fell swoop. You can filter by pc/npc/all.

and i LOVE that.  I am forever changing light stuff.
