SetScalarParameterValue called on trueSkyMaterialParameters with invalid ParameterName ‘MaxAtmosphericDistance’. This is likely due to a Blueprint error.
just loaded into 4.24 followed Cinematic tutorial you just posted – thats all i did
I had also this issue (it happens with the latest trueSky build), try to open the “trueSkyMaterialParameters” and add “MaxAtmosphericDistance” as a Scalar Parameters and set “Default Value” as you want.
and again it was totally black on hitting Play in selected viewport but works on Simulate
