| Parameter | Description |
|---|---|
| size | The width and height of each face of the cubemap should be the same. |
| format | Format of underlying cubemap object. |
| mipmap | Does the cubemap have mipmaps? |
| nativeTex | Native cubemap texture object. |
Creates a Unity cubemap out of an externally created native cubemap object.
This function is mostly useful for native code plugins that create platform specific cubemap texture
objects outside of Unity, and need to use these cubemaps in Unity Scenes. It is also possible to create a cubemap in Unity and
get a pointer to the underlying platform representation; see Texture.GetNativeTexturePtr.
Parameters passed to CreateExternalTexture should match what the texture actually is; and the underlying texture should be a Cubemap (2D textures will not work).
For Direct3D-like devices, the nativeTex parameter is a pointer to the underlying Direct3D base type, from which a texture can be created. They can be:
• D3D11: ID3D11ShaderResourceView* or ID3D11Texture2D*
• D3D12: ID3D12Resource*
For OpenGL/OpenGL ES, the nativeTex parameter is a GLuint.
For Metal, the nativeTex parameter is an id<MTLTexture>.
For Vulkan, the nativeTex parameter is a VkImage*.
