Dynamic lighting's dim light doesn't work the same as the Pathfinder rules, adjusting the multiplier just amplifies the bright light and dim light range where objects and creatures still display in an area of dim light despite a creature not being able to see in dim light conditions. To work around this, you basically have to match the emit light value with the light degrades to dim value and adjust the multiplier for low light and dark vision creatures e.g. Torch - emits light 20, 20 (players can see light-on) Low light vision character - multiplier x2 Dark vision character - emits light 60ft, 60ft (players can see light-off), multiplier x2. Adjust the range of the light emitting source and dark vision range as necessary for the given creature, spell or object. This should work for everything unless the range from dim light to darkness does not match the range of bright light emitted in which case the multiplier will produce an incorrect dim light view. This setup also has the downside of not receiving the graphical representation of light dimming on the map if you care for that sort of thing. Alternatively you can keep the lighting emitting values as they should be and then just half the multiplier for creatures that can't see in dim light or darkness e.g. Torch - emits light 40, 20 and (players can see light-on) No special vision character - multiplier x0.5 Low light vision character - multiplier x1 Dark vision character - emits light 60, 60 (players can see light-off) and multiplier x1. This will correctly display objects and creatures for the vision of the creature and maintain the graphical effect of dimming light.
