Hello!
We are building an interactive configurator for our Client.
Inside we need to have a color correction on everything but their products.
Therefore we used color correction regions (after we tried limiting post process volumes to certain objects which seems impossible) and are dynamically setting the “exclude actors” on runtime for the products that are spawned dynamically.
But there seems to be some sort of bug / feedback loop happening with Lumen because if we for instance increase the contrast of midtones to a certain degree, lets say above 1.5 it slowly starts to glow until everything where light from our sky is hitting a surface looks like it is literally glowing from heat.
Here is a Screencapture of the issue:
