How do I achieve different lighting using Live Lighting

[Jaffa]

I have an image where I want to have three lights.  I set up my first light, then *added* a light and then *added* a third.  Each one I set up the Ambient light and other features separately thinking that each would remain as set up.  However, then when I looked back discovered that they had all ended up with my last settings for the third light, Ambient 40% etc.  Why do they not keep the settings individually?  I then thought of trying using Copy, but the same thing happens.  Naively, I then thought that I would add an extra Lighting Layer, but as you will know that does not work, because only the top Lighting layer has effect.  I could separate the image into three and have Live Lighting Child layers, but do not want to do that.

How can I have three lights which have individual settings please?  😬

Ambient light is the indirect illumination coming from the surroundings, like what might bounce off walls & ceiling in a room. It is independent of illumination coming directly from the light(s) you add. There is only one setting for its intensity & its color because it is an aggregate effect.

For this, you could simulate the lighting effect with individual adjustments + layer blend modes, separately for each "light source" and / or "ambient light", each of them limited by an individual mask with the desired shape / blur. Alternatively you can combine such a workaround with the lighting filter, using the manual masks for ambient light only.

By "manual masks" you  mean?
