UDS has options to support the path tracer, which the readme goes over. Make sure you enable Adjust for Path Tracer to configure the sky to be rendered as a path tracer background using the sky light capture.

If you're trying to control exposure manually, make sure you disable UDS' auto exposure settings. The toggle for that is in its Exposure category.

Dust is part of the weather state controlled by UDW. So you could use a weather override volume to apply dust weather to a region.

The DLWE function just generally applies to any attributes routed through it, so it can work with any landscape material really. Get in touch at the support email with the specific issue you're having, screenshots of the graph ideally, and I can try to help. That's support@ultradynamicsky.com

Yes, there's a utility included called the Volumetric Cloud Painter, which can paint coverage or mask coverage of the volumetric cloud layer.

@@everettgunther929 Thank you for your reply. I'm new to the UE world and although I know about the painter, I wasn't sure it would work with UDS. Congratulations on your work, I'm going to buy it now.

It would depend on your foliage and what it's set up for. If it will respond to a wind directional source actor, you can select one of those on UDW to have it control its speed and direction. There's entries in the Material Effects section in the weather readme, about sampling UDW's wind in a material or using the included Foliage Wind Movement function.

If you're updating from a 5.3 project, make sure you Add to Project again to get the current release of the asset which supports 5.4. Try using Remove Local Content on UDS before adding, to make sure the launcher downloads latest.

It's an engine bug I've seen in 5.4 with some of the film/tv/virtual production templates. An amount of the atmosphere color renders incorrectly in front of sky materials. You can fix for it by setting the Atmosphere Sun Disk Color Scale to black, on the Moon directional light component on UDS.

In the current release, you could adjust Rain Ambient Light Intensity. That scales the amount of the sky ambient color they light with diffusely. If you're back in the UE4 version, the rain are just normal lit translucent materials, so it's just a result of the amount of actual sky lighting.

@@everettgunther929 Thanks for your answer so, in UE5, even with a kind of dark / dusk lighting, you can "cheat" the look of the rain so it is more visible, right ? Is there a way to contact you and share a couple of screenshots ? I'll investigate following your answer ! thanks again

Sure, sometime in the near future, to cover version 8. These product videos take a lot of time to make, this one took a couple months. So I need to space them out.

I would say get in touch at the support email with details and crash logs. I don't know of any crashes which the current release can cause in its supported engine versions, so make sure you're updated as well. The support email is support@ultradynamicsky.com

@@everettgunther929 I will try. Thanks very much!

The editor is very tempermental about moving entire asset structures like UDS. First, make sure everything is compiled and running in the UDS demo map. Then restart the editor and open an empty level (so no UDS assets are in use while you do the move). Then move the files and fix redirectors on content. Then restart the editor again and open the UDS demo map, letting it recompile as needed. But also, I really do recommend just keeping it in the default location, as it makes installing an updated version of UDS much much easier.

@@everettgunther929 Appreciate the reply! Sounds good I'll just suck it up and keep it top level to make updates more smooth. My OCD will adjust hehe. Love this sky/weather system man. Nice work!

There is no effective max size to the UDW area. It moves with the camera location infinitely. If particles are spawning in one spot, like the origin, and not moving with the camera, make sure you're updated to the current release of UDS, for the engine version you're using.

You could use the surface weather effects material function on the material applied to your characters, sure.

@@everettgunther929 that's what I was kind of thinking, thank you for the replies & sorry about bothering you so much haha

There are entries in the readme with steps for working with sequencer, in both the sky and weather sections.

@@everettgunther929 Thanks for reply, love this Blueprint. Unfortunetly i'm not able to make any changes in sequenzer for this Blueprint, to set up the keys. Maybe is to advanced for me. There are also no other tutorials for workflow in sequenzer.

@@everettgunther929 So i was able to make changes in sequenzer, but everytime when sequenzer ran, trees and grass dissapear, or has flickering issues.

@@nasi3228 If it seems connected to UDS in some way, get in touch at the support email with screenshots/video and we can troubleshoot properly. That's support@ultradynamicsky.com

This would be something to contact the support email about. That's support@ultradynamicsky.com

Yes, the unreal marketplace license allows for commercial use.

It's something which has already been fixed in the current version of the asset. You should just need to update.

In the UE5 version, the sand/dust material effects have all the same capabilities as the snow effects, yes. Including the interaction effects for objects leaving trails in the snow/dust.

Not sure what you might mean specifically. If you've added UDS to your project from the launcher and the blueprint assets aren't there, I would say try adding again.

I don't know anything about that time system, but on UDS itself, all you need to do to set the time at runtime is set Time of Day, yes.

@everettgunther929 set time once yes but then static time. I want day night cycle.

@@Flawlessjess Yeah, there's nothing stopping that on UDS' side. You would just set Time of Day on tick/periodically.

UDS is a blueprint asset pack, not a plugin. You add to your project, you don't install it to the engine. If when adding to a 5.3 project it's showing an error like this, that would be a bug with the launcher. I'd recommend using "remove local content" on UDS to redownload, and if that doesn't work try reinstalling the launcher.

@@everettgunther929 I used the wrong word, plug in or blueprint, it was not installing from the marketplace. I ended up having to restart my machine and unreal a few times. eventually it worked.

Here in the UE4 version just snow and puddles. The UE5 version did add dust/sand weather, with dynamic dust/sand coverage which works the same as the snow. No specific options for mud, no.

That would indicate that tile's instance is going past some limit for material compilation, with the DLWE effects added on top. It was probably just close to that limit already without DLWE. One common thing for landscapes is the number of texture samplers. Make sure all your tiled textures on your landscape mat use Shared Wrap mode for their texture samples.

@@everettgunther929 Youre the man!

First, in case this is just an editor error with niagara compilation, try opening the Rain system in the Particles folder, and doing Full Rebuild, from the Compile dropdown. If that doesn't work, get in touch at the support email with more details. That's support@ultradynamicsky.com

By default, the sky colors will come from the settings in the Sky Atmosphere category.

Note this video is just a brief overview of the product for new users. There isn't any info here that isn't covered in more detail in the documentation.
