I’m working on Light Probes blending. here is the first result.
I have 3 probes aligned in a “corridor” with emissive walls.
At the beginning I use what we have today: the geometry uses the closest probe. So the floor geom only use the central one (the closest probe to it’s “center”) and the cube switches between the 3 probes depending on its position.
You can see a sudden lighting change when the cube switches probe.
At around half of the video I switch to the new mode. The floor now uses the 3 probes and they are blended on a pixel basis. Notice how the reflection parallax is better, However It can’t be perfectly aligned unless I implement oriented box bounds for the probes… work for another day.
However the cube now goes smoothly from one probe to another, with no lighting sudden change.
