Question Best solution to image format support for add ref library image at runtime

When adding images at runtime to a mutable reference library i get this error:

Code (CSharp):

1. The texture format ETC_RGB4 is not supported by the current image tracking subsystem.

I looked up the source code and found that RGB 24 bit works but my question is whether that is the best solution or am i missing a setting that would allows other formats to work?

 

Code (CSharp):

1. mutableRuntimeReferenceImageLibrary.supportedTextureFormatCount

returns the number of supported texture formats and

Code (CSharp):

1. mutableRuntimeReferenceImageLibrary.GetSupportedTextureFormatAt(int)

returns the enum values of supported formats. You can loop through them and change your textures formats

Code (CSharp):

1. for (int i = 0; i < mutableRuntimeReferenceImageLibrary.supportedTextureFormatCount; i++) {
2.             Debug.Log(mutableRuntimeReferenceImageLibrary.GetSupportedTextureFormatAt(i) + "\n");
3.         }
