I’ve been doing ready to play maps for Foundry VTT since its launch in May 2020. These maps are preconfigured with walls, light sources, doors, and weather effects. If you are a Foundry VTT license owner, you can download my free Battlemap Starter Pack here. You can install this module also straight from the Foundry VTTs dashboard (Modules tab > Install Modules).
Premium Battle Map Modules
I also have premium map modules available to my Hero+ tier patron on Patreon. These premium modules are updated regularly with new content and features. In comparison to the free starter module, they include more variant versions per map and some maps have also soundtracks.
The premium modules are divided into volumes with 10 maps each.
