TurnMarker-alt VS combat-utility-belt

Here's a simple example: Turn Marker. It's system-agnostic, it does something really simple: renders an animated image around the token with the active turn. It worked from version 5 through version 9. In fact, it worked for version 10 for a while and then suddenly stopped working. Somebody tried to create an "alt" version and kind of got it working, but it was flaky. Finally a more active contributor, Monk, released their version just three months. That version supports 10, but does not have a release for 11.

Turn Marker - Highlights the token for the currently active combat actor. This is an alt version as the original is/was abandoned.

If you can't find anything else, there's a commit sitting in the Turn Marker pull requests on GitHub that updates to the v9 API. It just hasn't been merged into the main branch yet. This link is to the branch with the (theoretically, haven't tried it myself yet) v9 compatible version. You might have to download and manually install it, but that might work for you. Depends how comfortable you are in getting that set up and how badly you want the module. It honestly shouldn't be too hard, but like I said, I haven't tried it yet. (Though I intend to in the next week or so once I update.)

Regarding Turn Marker in 0.8, the author appears to be absent and hasn't updated their module for the latest Foundry build. However, I've already submitted a fix for the player visibility issue that will hopefully get merged once the author returns. In the meantime, you can always update the code of this module to include my fix manually - feel free to reach out if you're unsure how to go about this.

Alternatively, you could use the Starfinder system on square grid maps, and then a PDF viewer + hexagonal grid maps for Lancer. Rather than relying on two systems, have the more complicated system handled by Foundry, and run Lancer on paper, using form-fillable sheets. Since both systems are D20, you can still resolve everything in Foundry - you'll just need to either make some dice macros, OR (my suggestion) grab the Dice Tray module, which can make it so much easier to quickly resolve dice rolls. https://foundryvtt.com/packages/dice-calculator . You can also use Combat Utility Belt to manage your Lancer effects within Starfinder, granted that there will be a bit of setup. https://github.com/death-save/combat-utility-belt

Enhanced Conditions from Combat Utility Belt (there are others that can be used for it - like DFreds Convenient Effects - but CUB is simplest).

Combat Utility Belt: Mostly used just for hiding combat names, but lots of other functionality

I use this purely for the Enhanced Conditions/Condition Lab to put the CPR specific effects in (critical injuries etc..)
