Perfect Vision (Foundry VTT Module)

Perfect Vision provides additional lighting and vision settings and lets allows you to control lighting and vision locally within the shape of a drawing. It gives you the ability to control the maximum vision and detection ranges within the area of drawings, lights, templates, and scenes.

Perfect Vision adds/exposes the following lighting and vision settings. - Global Illumination: The global light source is fully configurable with all the usual light options. - Animation Resolution: Controls the scale of the animation of the light source. - Daylight/Darkness Color: The illumination colors at Darkness Level 0 and 1 respectively. - Reveal Fog of War: Reveal the fog of war for all users. This does not override the saved fog exploration progress. - Vision Limitation: Configure the maximum range that tokens can see. - Vision Range (In light): Controls the maximum distance a token can see in illuminated areas.

A drawing allows you to change the lighting within the shape of the drawing; see Lighting tab of the drawing config. With the Fit To Walls option you can quickly fit the shape to the underlying wall structure; this is a lot faster than tracing the boundary of the structure with the polygon tool. For polygon drawings I recommend the Advanced Drawing Tools module, which makes it possible to modify polygons in case you make a mistake or need to change the shape. Each roof/level tile inherits the lighting settings of the drawing linked to it; see the Lighting setting in the Overhead tab of the tile config. By default roofs/levels use the lighting settings of the scene.

Perfect Vision improves the token visibility test such that tokens close to a wall won't be visible through the wall on the other side it. It also includes multiple performance improvements; most notably fog exploration optimizations, which eliminate lags/freezes almost entirely that occur when the fog exploration is saved.
