Perfect Vision is not going to be updated for V11.

• Enhanced Global Illumination: You can configure CONFIG.Canvas.globalLightConfig in a world script.
• Daylight/Darkness Color: You can set CONFIG.Canvas.daylightColor and CONFIG.Canvas.darknessColor in a world script.
• Improved GM Vision: Replaced by the GM Vision module.
• Light Animation Resolution: No replacement.
• Light Delimiters: No replacement.
• Lighting Drawings: No replacement.
• Reveal Fog of War: You can reveal the fog of war with this macro.
• Vision Limitation: Replaced by the Limits module.
• Vision Range (In light): Replaced by the Light Perception detection mode of the Vision 5e module. No replacement for systems other than D&D 5e.

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.
