Beautiful video! A lot of useful infos!

I was recommended to use this since my emissive particle material is showing up as white the center. But adding this seems to make the emission no longer volumetric (which is the default behavior). In UE5 fwiw. Happy to share more info if you can help out.

This definitely increases the lighting saturation, but it seems like it also disables a bunch of other useful rendering features like bloom and exposure (which is particularly a problem because it seems to be very dark, by default). Shame there's no way to easily modify the built in tone mapper.

Hi I need some help with this. I created a ppm pf the uncharted 2 tonemapper and during this journey noticed that a lot of post processing features are also replaced. things like bloom, chromatic abberation etc. do you have some guide or best practice to add this back in? .eg in which order these things are added, how to recreate these effects etc.

Off topic but Is there any way to make individual volumetric clouds ??

[boudini]

Thank you, fantastic tutorial! However, I have found that I'm getting quite pronouced banding on my skybox gradient which is using normalised absolute world position (not a texture) when using this tonemapper. I've tried to see if its my settings, but I can't seem to reduce it. I feel like I might be losing precision somewhere, do you have any suggestions?

How can I implement this effect on a single emissive material?

Hey, your link to GT tone mapper pastbin is not working it's blocking any emessive material which is working in your screen can you check back ur GT tone mapping ?

[yonjuunininjin]

This seems to be broken in Unreal Engine 5, right?
The Post Process material just makes everything dark and the bloom is completely disabled for me.
I double checked, the material is replacing the tonemapper and no other post process variable is touched.
