Dmitry,
Awesome! Works perfectly. Thanks.
Hi @Dmitry_Karpukhin, I just downloaded the latest version available for 4.26 from the EGS, but it shows as 1.30 in the Plugins list in UE; is this correct?
Iâm also getting a crash when compiling a child BP of SkyCreator:

Iâm also redoing my weather presets (given the clouds change), and noticed the Sun Light | Intensity property set in the weather preset is ignored (the value set in the SkyCreator BP is always used).
Hello!
Itâs correct, the last version of the plugin on the 4.26 is 1.30. For the newest versions you should try latest engine versions, starting with 4.27 (Iâm only able to support the latest 3 versions of the engine as a plugin developer).
Yes, 4.26 is full of Niagara crashes and this is one of them. Itâs a rare circumstances combined that triggers the bug and I believe itâs because Weather FX of Sky Creator are using GPU particles. Itâs fixed since 4.27, you can create a child BP of SC with no problem there.
To enable weather presets using Sun Light Intensity parameter, you should disable the âSun Constant Intensityâ variable on the SC actor.
Thanks! Weâre switching to UE5.1 soon (skipped 4.27): glad the crashes are known and solved in later versions.
I might have missed this in the docs, but whatâs the best way to set North? Simply rotating the SkyCreator actor and assuming North is 0° yaw?
Thatâs right! Easy as that. The actor itself has a compass mesh which will point at north.
Great thanks!
Hi @Dmitry_Karpukhin, me again. It seems the lightnings Niagara asset isnât being packaged, since I get this error in packaged games only:
LogStreaming: Error: Couldnât find file for package /SkyCreatorPlugin/Effects/SC_WeatherFX_LightningStrike_System requested by async loading code. NameToLoad: /SkyCreatorPlugin/Effects/SC_WeatherFX_LightningStrike_System
Lightning strikes are indeed invisible, but theyâre definitely spawning since I can see the clouds light up around the spawn point.
Adding +DirectoriesToAlwaysCook=(Path="/SkyCreatorPlugin/Effects") to DefaultGame.ini seems to fix the issue.
Also, is there a way to have precipitation below the mapâs XY 0 plane?
Hello!
Hmm, thatâs strange. I usually test and package all the published versions, but this never occured to me. Thanks for reporting, Iâll double check that.
Iâll link the answer to a second one: Documentation â Dmitry Karpukhin
Looking at the reference viewer that particular asset isnât referenced by anything (I guess itâs loaded somewhere in the code), so UE doesnât know it has to package it. Maybe youâre testing with the cook everything setting?
Regarding the other issue, thanks. I did try the Cutoff World Height setting on the Weather FX component, but I couldnât find the Material FX component. I now realized the setting had to be changed in the Weather FX and Material FX categories of the BP.

can anyone help me create lightning effect, thanks
Does this plugin have support for âplacedâ clouds (ala UEâs Blueprint Placed Clouds) or otherwise ways to directly control cloud locations?
No, but this is in roadmap for the next 1.4 version.

Hi Dmitry!
Awesome plugin, but iâm currently experiencing this behaviour on my env, Changing mobility to skylight fixes, but i lose the ambient occlusion on a lot of meshes. What is causing this?
It does not happen in usual circumstances (I often test SC on various environments from marketplace), so I donât know. Could be anything.
i noticed that this problem started when enabling âgenerate distance field meshâ to allow distance field shadows to work.
Hi Dmitry!
Very promising and awesome plugin. Is there an option to place manually a lighting effect?
Thank you!
Yes, there is a built in blueprint function called âSpawn Lightning Strikeâ.
Hi Dmitry,
Iâm recently using your plugin to build my flight simulator, when I using path tracing mode, it shows all black below. Could you give me some suggestions?
Hi! What is your engine version? I think turning off âLower Hemisphere is Solid Colorâ fixes it, if itâs 5.0.
