Hi ! I’m trying to make my own skybox by following this tutorial :
HOW TO MAKE HDRI MATERIAL UE4 - YouTube.
I have an error since I linkeded Normalize to my HDRI Parameter :
(Node TextureSampleParameter2D) Coercion failed: MaterialFloat3 Local4 = (Local1/Local3);
Can someone explain how to resolve it please ?
Thanks a lot !
ParamCube, not Param2D 
Thanks. I just dropped my texture in the blueprint as he did in the video so I didn’t see that it’s not the same kind of parameter. I put the parameter manually and when I gave to it my texture, I got the following error message :
[SM5] (Node TextureSampleParameterCube) ParamCube> Found Texture2D, requires TextureCube
Do you know how to convert my Texture2D to TextureCube ?
Start with a texture cube
Is your texture definitely a cube? ( that might be why drag drop doesn’t work ).
My texture is not a cube.
I’m a bit confused, you called it HDR sky
And the material code you have there is for a texture cube ( hdri map ).
Yes, it’s true. But I don’t have a textureCube, just a 2D texture. Now, I would like a way to convert my texture to textureCube.
Ah. You can’t, unless you’re Einstein
Start with a cube. They’re free, from
Okay, thanks.

I found a way to make a HDRI textureCube and it works well :

That’s right, easy to make from scratch, but not from an existing texture
I have a new problem now with my HDRI material. I tested the game I’m making and I got just a pink sky :
However, I would like to see this king of thing :
Do you know what I have to do to see the landscape ?
To see the landscape, you have to remove your actual landscape
But I don’t think it’s working, I don’t see any sky…
Can you show the material?
I get:
Well, that’s exactly what I have.
Does it work if you just put the sky sphere in an empty level?
You get the correct preview?
Where did you get the sphere? I think the UVs are messed up.
There’s an HRDI plugin, you just need to enable it
put it in the level, and just drop your texture here
I found the sphere in the Place Actors window and I changed its basic static mesh with a SM_skyspher mesh as they do in the video I watched.
With your method, it works well but what about the videos ?
