I have a torch scene with a light 2d and when I put two or
more I proximity they stack and can be really bright where
they overlap. I use add mode and have tried mix mode
but it doesn’t look right.
Can anyone help?

For anyone else struggling with this I wanted to share
my solution.

I found that mixed mode does in fact solve
my overlapping problem. It’s not a perfect solution as
the edges of the texture create a kind of bubble mixing
interaction. And the middle of each seems to darken a little.
The effect is subtle enough that I can overlook it. I would
prefer that the edges blend in add mode but don’t have any
way to do that in version 3.4 of godot.

Also, I have a particle texture that was getting darkened
when I switched to mixed mode. I had to play with both
the modulate and self modulate properties of the particle
emitter to make it look bright and vivid.
