Light issue dark meshes

Hello !
I have an issue with some assets in my game.
I did some Level Design and create a village and built the light (I am using Ultradynamic sky).
The light is perfect, except for one of the house.

As you can see, when you are far from the house, it appears well. But when you are a little bit closer, it becomes black. I don’t think it is link to my shadow that are too strong, because when we see the shadows on the others house it is correct !
I am using 4.26
I am not sure how I can solve that… Thank you for your help and time !

All the best :slight_smile:

Do you have a skylight?

Hello again ! :smile:
Yes, I have a sky light :slight_smile: I am using ultradynamic sky actor so it contains everything.
Here is a picture where you can see the shadows on other houses

As you can see, it is good there ! The houses are all coming from the same pack of the marketplace, not sure why only one is causing issue…

And it’s not static lighting?

5

No it is movable :slight_smile:

6

It the Ultra dynamic actor at 0,0,0?

I’m stumped… :thinking:

No it wasn’t. So I set it to 0 0 0 and build the light again but unfortunately it doesn’t solve the house problem.

check the UV’s see if they have any issue

Sorry but I don’t know what exactly I have to check on the UV ?

10

The UV must be ok, because it’s alright when the light is on it, right?

Take a look at the scene is distance field visualization ( MDF & GDF )

11

By using the show option → visualise and mesh distant field ? Because it says me it is disabled in project settings…

12

That’s not going to help, Lumen needs distance fields to function.

13

the uv ideally should not have overlapped polygons, be proper UV for games, if you open the object/mesh you will have an option to see how the UV looks.

Thank you, it was the real problem. UV was bad, I look some tutorials and manage to regenerate them inside UE4. Then build again the light and it is good now ! It wasn’t a light problem as I thought at the beginnning.
