How to use

Export assets

1. Right-click on the asset ('Texture Render Target Cube' or 'Texture Cube').
2. Select 'Asset Actions -> Export'.
3. Choose file format and save the file.

Blueprint API

See Blueprints example.

C++ API

1. Add CubemapExport module dependency into your project's module (.Build.cs file):

PublicDependencyModuleNames.AddRange(new string[] {
  "CubemapExport"
});

2. Use API function to export cubemaps:

#include "Engine/TextureCube.h"
#include "Engine/TextureRenderTargetCube.h"
#include "CubemapExportLibrary.h"
...
UTextureRenderTargetCube* RenderTargetCube;
UTextureCube* TextureCube;
...
UCubemapExportLibrary::ExportRenderTargetCube(RenderTargetCube, TEXT("E:/"), TEXT("RenderTarget.png")); // Export render target cube as PNG
UCubemapExportLibrary::ExportRenderTargetCube(RenderTargetCube, TEXT("E:/"), TEXT("RenderTarget.jpg")); // Export render target cube as JPEG
UCubemapExportLibrary::ExportRenderTargetCube(RenderTargetCube, TEXT("E:/"), TEXT("RenderTarget.bmp")); // Export render target cube as BMP
UCubemapExportLibrary::ExportRenderTargetCube(RenderTargetCube, TEXT("E:/"), TEXT("RenderTarget.exr")); // Export render target cube as EXR
UCubemapExportLibrary::ExportRenderTargetCube(RenderTargetCube, TEXT("E:/"), TEXT("RenderTarget.hdr")); // Export render target cube as HDR
...
UCubemapExportLibrary::ExportTextureCube(TextureCube, TEXT("E:/"), TEXT("Texture.png"); // Export texture cube as PNG
UCubemapExportLibrary::ExportTextureCube(TextureCube, TEXT("E:/"), TEXT("Texture.jpg"); // Export texture cube as JPEG
UCubemapExportLibrary::ExportTextureCube(TextureCube, TEXT("E:/"), TEXT("Texture.bmp"); // Export texture cube as BMP
UCubemapExportLibrary::ExportTextureCube(TextureCube, TEXT("E:/"), TEXT("Texture.exr"); // Export texture cube as EXR
UCubemapExportLibrary::ExportTextureCube(TextureCube, TEXT("E:/"), TEXT("Texture.hdr"); // Export texture cube as HDR

Known limitations

1. Alpha channel is not fully supported and filled with 255 or 1.0 values (in case of various formats).
2. PNG format is exported only with 8-bit depth.
