This FoundryVTT module adds support for projected walls which are needed when using isometric or 3D-projected maps. This works by adding dynamic walls at runtime, just in the right position to produce the correct vision cone. Still 2D and not perfect, but a lot better than static walls. Such maps can be produced using Unity2Foundry.
Unity2Foundry is a toolset that allows you to render maps from within Unity Editor, while also generating wall-data for FoundryVTT. That means you can use tools like ProBuilder and/or get some 3D game assets from the Unity AssetStore.
Some screenshots of FoundryVTT scenes made for the StarTrek Adventures episode 'The Ångström operation' from the second mission compendium. Note that the compatible Shared Vision module by CDeenen was also used for those screenshots.
