Auto Exposure on emissive color even when off

Hello everyone,
I’m having an issue where it seems like auto exposure is still being applied to my scene even though it’s off on both the camera and a global post process volume. I’ve also crushed the HDR range so it does not change. Motion blur is also off. The problem persists.

I basically have an incredibly simple grid. Unlit material. Emissive and opacity are the same texture. When standing still it looks fine. When moving it is very faint. When the camera comes back to rest it seems like it’s getting some kind of auto exposure applied to bring it back into the scene.

I want it to not do this.

Here is it still:

Here is it in motion:

Notice how faint the lines are. If I disable all post processing while playing (pressing F2) it looks how I want it; though of course I’ve now removed all post process effects which is not what I want.

Finally I have a youtube video demonstrating the issue and my setup if you’re interested in taking a look.

I’d really, really like for someone to be able to help me with this. Thank you!

I’ve found if I switch the grid material to a masked blend mode this problem does not happen.
Can anyone provide me with resources in understanding why this is? :slight_smile:

Hey Weaver -

This is probably caused by the Temporal AA in the engine. Try checking the “Enable Responsive AA” when you have a Translucent Material this will probably fix this blurring effect you are seeing. If not, you can also disable the Temproal AA in your Post Process settings switching to FXAA is an ok compromise.

Thank You

! It was the temporal AA :slight_smile:
