Recommended General Compatible Modules
The following have been tested with Rolemaster Unified. The RMU system will recognize they are enabled and will use them if they are activated.
The three asset collections/modules below are available for free or as premium. The best experience requires the premium content, but the Rolemaster Unified system will work with either. At the time of writing, all premium versions only required one month of Patreon subscription to access their entire back catalogues of assets.
Forgotten Adventures offers topdown tokens in both .png (higher quality) and .webp (smaller file sizes) (https://www.forgotten-adventures.net/tokens-library/).
The official Creature Law module includes a preset file that maps many of these token images to creatures so that when you drag one to a scene it will have token art. The best experience requires the premium content as Creature Law is set up to choose a random variant of the token, but Forgotten Adventures offers at least one version of each token for free.
If you download these and store them in your "data", you can enable the token art presets in the Game Settings for RMU Creature Law I.

Both JB2A and PSFX require the Sequencer module to be installed. If you install either JB2A or PSFX inside Foundry, it will prompt you to also install Sequencer.
