IMPORTANT
This module breaks in 0.7.x and is considered end-of-life in 0.6.x. I will continue to explore options for similar functionality in 0.7.x, but the lighting and vision systems have changed dramatically, and the solution from 0.6.x (using a PIXI built-in blend mode that just happened to work) will likely require a custom shader in 0.7.x.
Thank you for all of the support and desire to see this module ported. Apologies for not being able to support this feature in the short-to-longterm.
This module attempts to replicate dnd5e darkvision rules more accurately, leveraging the existing dim vision setting on tokens' vision tabs.
The default Foundry VTT behavior when dim vision is set does the following:
- Renders
darknesswithin thedim visionradius asdim light - Renders
dim lightwithin thedim visionradius asdim light - Renders
bright lightwithin thedim visionradius asbright light
Darkvision rules as written for dnd5e actually increase each level of light below bright light by one step within the dim vision radius. The desired behavior is:
- Renders
darknesswithin thedim visionradius asdim light - Renders
dim lightwithin thedim visionradius asbright light - Renders
bright lightwithin thedim visionradius asbright light
An experimental grey-scale mode can now be accessed on a per-user basis in module settings. Enabling this setting will desaturate anything that a dim vision token would see in areas of darkness. This comes at a cost, however:
- performance: this grey-scale effect is a filter that is running any time a token with
dim visionis selected and may cause performance issues - image fidelity: this filter can reduce token, background, and tile image quality when it is in effect for some (maybe all) browsers
- personal space: something about the filter reacts poorly when you zoom in too much, causing the screen to go black.
dim visiontokens like their personal space. Just zoom back out to see your token and the scene again.
- Selecting multiple tokens simultaneously will render lighting inconsistently.
