When I drag the 1896x948 PNG image into the Unreal content browser it’s fine, but when I then drag it into the HDRI Backdrop plugin (Cube map section) it doesn’t go in or seem to be accepted. I already have a default Envirodome set in the HDRI Backdrop plugin Mesh section, I’ve tried other default meshes but the result is the same. How do I get it to accept my image which I’m trying to use as HDRI Backdrop? Could anyone help please? It would be greatly appreciated 🙂 I have access to Photoshop too. R ---

The image needs to be in HDR format. You can’t just drop a texture in there 🙂 Have you tried saving it explicitly in HDR format? When you edit the texture, it should look like this: ![351610-screenshot-6.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/8/3/c/83c57fd7a841a9ebf1d270bdfd122a27c63f989f.jpeg) It’s also a good idea to change the maximum texture size to at least 1024 ( also in pic ), so ‘no mipmaps’ ( further down in settings ). ---

Thanks for the quick reply @ClockworkOcean! I tried saving the texture as a HDR in Unreal like you suggested and also the settings, but I am still unable to drag it in? Any further thoughts? Also, when I change the texture to HDR format, the color of the image suddenly changes and becomes a lot lighter. Any idea of how I keep it the same? or would I just adjust the Unreal settings on hue, exposure etc. R ---

how did you sort this out, pls? I’ve run into the same issue and can’t seem to find a workaround? ---

One possible reason is that Unreal does not seem to accept uncompressed 32bit cubemaps. I had this issue with hdri maps from [polyhaven.com](http://polyhaven.com) (linked to in the documentation as “HDRI Haven”), even with all the necessary settings. It later did work when using the maps **in .hdr format instead of .exr format**. Exr-files are 32bit and shown in the content brower as “Textures”. Hdr-files are 16bit, widely more supported and shown in the content browser as “Texture Cube”, only these are accepted. ---

Agree, open the exr in PS and saving it as .hdr worked
