Hi, I’m sorry to hear that you’re having problems. Originally, the EXR files were intended to be used in the Unity engine, so I haven’t tested them in Godot. If you can give me more information, such as the exact error message, I might have more insight into the problem.
For now, try reimporting the images in a photo editing software to match Godot’s standards (maybe convert them to 16-bit instead of 32-bit).
