Hi @chakarov , thanks for taking the time to answer,
The mode should be “Full”, but I’ll double check
Then is probably a bug, lightMix is not generating “Full” light slects.
To divide light contribution to direct,indirect and full you could use Manual mode of LightMix and add LightSelect elements you need.
Sure, but that way you lose the ability to get the light selects automated…bummer. One of the cool things about the lightMix is to not have to use lightSelect elements, just throw a lightMix and output all light selects automatically.
You could set LightMix to Manual mode and add as many LightSelect elements as you need by grouping lights the way you want
Same answer as before, lightMix is cool because it outputs light selects automatically.
The value and color in LightMix controls in VFB are just multiplier for light parameters, it is done this way because you could combine lights with very different intencity or colors but control them in one place.
We discussed this internally and everyone was of the opinion that this color and intensity values would be better if they were the values of the lights. The reason you mentioned to use those values as offsets would actually only work if users set the lightMix to “Manual Mode” and use more than 1 light in the light selects, otherwise in “Instanced Lights” mode the lights cannot have different color or values since they are instanced, and in “Selected Objects” mode the lights selected are all individual, so no group of lights to offset here.
Plus this raises some issues regarding offsets, if I have a light with a color value of 1.0, 0.0, 0.0 (Red), how can I offset that light to add a green and blue components to it? I can’t, the value sliders can only go down. Second example, my light has a value of 33, 20, 18 (hight values are normal when sampling lights from plates) and I’m matching this color to a plate by color picking it’s RGB values, and now I need to offset my light to match the individual RGB components, how can I offset the individual components up, or increase it’s saturation? That doesn’t work to, we can’t make values go up and if all I want is to saturate a color, by sliding the saturation slider up, it doesn’t do anything because it takes the white color as a base, not the light color.
When working with plates matching light usually is a precision work of reading and matching values, and working with offsets this way does not allow for that, we would really like to see this changed to reflect the exact color and values of the lights.
Best,
David.
