It’s works all fine for FLinearColor (variables added to blueprint actor), but it doesn’t work for FColor.  
And this is big issue because FColor is used in components like AtmosphericFog, SkyLight and similar built-in components.

Does Sequencer support FColor at all?

Repro

1. Add Atmospheric Fog actor to sequence.

2. Add track for Atmospheric Fog Component → Default Light Color.

3. Add key, try to set value of that key. Nothing happens, value remains equal to zero…

Hi,

Thanks for the report. This has been fixed and will be available in 4.16.

For tracking purposes, the jira for this is UE-41645. I’ve asked to make it publicly available, so hopefully the details of it will be available soon.

This still seems to be a problem with 4.26?

I set keys for white “default light color” in the details for the atmospheric fog but when using sequencer it jumps back to black even though they keys are white?
