Hi ! I’m trying to make my own skybox by following this tutorial : [HOW TO MAKE HDRI MATERIAL UE4 - YouTube](https://www.youtube.com/watch?v=mhgbAs1-9A8&t=143s). 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 ! ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/a/c/6/ac673f57e8de6a6b48ed84bc74138cc07f33c90a.png) ---

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 : ```auto [SM5] (Node TextureSampleParameterCube) ParamCube> Found Texture2D, requires TextureCube ``` Do you know how to convert my Texture2D to TextureCube ? ---

Start with a texture cube ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/e/a/9/ea9de26d57affcccebecdb828d5570c90cc3d5cc.png) Is your texture definitely a cube? ( that might be why drag drop doesn’t work ). ---

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. ---

I have a new problem now with my HDRI material. I tested the game I’m making and I got just a pink sky : ![screenshot1](https://d3kjluh73b9h9o.cloudfront.net/original/4X/b/b/5/bb574d82041427f201b1d31e0d88a363ddea4221.jpeg) ---

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: ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/1/8/1/181445423aab86e75617cc4eaa4f0243d7a536ff.jpeg) ---

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? ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/f/6/b/f6b8ba9820fb2e362663d95004602a85060c6f90.jpeg) ---

Where did you get the sphere? I think the UVs are messed up. There’s an HRDI plugin, you just need to enable it ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/6/9/8/6982dae99b7ac72827d97716a3467a716be3b161.png) put it in the level, and just drop your texture here ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/2/4/4/244f59dc6bb9546adcd3f1bdaabc57b28632510d.png) ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/4/1/5/415013308c320d9ae4c2e8adf592ca8a1139b37f.png) ---

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 ? [Next page](https://forums.unrealengine.com/t/errors-when-im-making-my-own-hdr-skybox/739428.md?page=2)
