Question on Weather effects & textures

[vincentlincoln]

Hi, I am using Airsim for drones. Currently there are no texture effect from weather, excepted some effect on camera. I am a beginner with Unreal Engine. I know that there are Weather SFX uassets in Airsim. How do you apply all of them on all objects & grounds?

i want to have snow, water effect or any other weather effects on the ground & objects.

Do you have any guide or tutorial?

(Note: i have the UDS plugin which also control weather, are his attributes accessible from Airsim or do i need Unreal Python or code in c++?)

Thanks

@vincentlincoln just checking, did you follow this method to set the weather api? From the wiki, the weather APIs are disabled by default.

Yes , i did but the weather effects aren't applied on ground/object textures. According to the documentation, i need to apply Road Wetness, Roadsnow and roadleaf, but there are no further indications.

I am using Cosys Airsim on my own map.

You need to add materials to your scene for it to read from the weather API i believe, I have not used these myself though.
