Realtime Dynamic GI + Reflections + AO + Emissive - AHR

Test map is brillant. everything works.
But when i’m trying to create my own indoor map scene.
Everything is always too bright.

By the way scene is being created from a blank map with nothing.
With black boxes around the white walls.
No lights so there’s not even a possibility of leaking.
When i add lights not much difference.

I did a few tweaks, is more like it?

I just played a bit with the settings. Will upload the modified project later. kind of scenes are where at least 2 bounces are required, look strange without them. Also, 5 rays here are too little. When I finish the re-work of the algorithm, the number of rays will be tweakable parameter, so that will make it much easier to control quality/performance. Quite confident that kind of scenes with multiple bounces and about 8 rays should look really good.

Adding, as you call it, “a bit of the albedo” to irradiance. Or rather, as I did it while messing around with some SVOGI stuff, made the ambient light affect the irradiance GI output rather than the normal albedo. Tried to convince some people on Gamedev.net that it was a good idea, but they didn’t go for it for whatever reason. Worked well when I tried it, and when I looked it up later I found out it was something Pixar had done for a lot of their movies.

Not only does it make “non lit” areas show up in specular reflections, but it gives a nice and frankly realistic color bleed. Of course, the way your doing it is straight adding albedo to the irradiance, which I imagine would make the secondary color bleed a little too strong and saturated. For a more realistic look you could try shading your voxel albedo as if it was being lit by a greyish ambient light (user selectable ambient light) and then having that be added to the irradiance output.

Frenetic Pony, that kind of scenes is where adding the ambient light break stuff, with that corners get a white light, that’s just appearing magically.
EDIT : Can you give me some link to the disney stuff? Would love to read it.
Will add a slider to change the amount of ambient in the grid, as it works quite good on some scenes, but it breaks in others
For comparison, here’s a pic with and without the ambient light (exaggerated to show the problem)
