Smooth Chunk Transition in Distant Horizons Still Available in Fabric 1.21.7?

Hi, It seems that in one of the recent updates, Distant Horizons added a smooth transition between vanilla chunks and those loaded by the mod. I'm currently playing on Fabric version 1.21.7. Could you tell me if this feature is still available and where I can find or enable it?

bloop had a DH related update with better support recently, but idk what it added exactly
