Hey all, when using `engine.setTextureFormatToUse`, is there a way to be selective about what it tries to apply \<-format\>.ktx to ? Its trying to apply it to every texture no matter how its loaded(environment map and a bunch of accent/background models we don’t have ktx pipeline set up for etc… )

Edit: the ones that need the format behavior are being loaded as loose `Texture` if that helps

Thanks

I think all of this has been improved quite a bite by @Evgeni_Popov ???

No, I didn’t do anything related to `setTextureFormatToUse`.

Maybe you can use .ktx2 files instead for the assets that need texture compression?

Adding @bghgary as he will probably have more answers regarding `setTextureFormatToUse`.

@Evgeni_Popov I can give that a shot. I thought ktx2 did not support PVRTC but I am mistaken and it gets transcoded. This is the best writeup I ever seen explaining all that: [Basis Universal GPU Texture Codec](https://reposhub.com/cpp/miscellaneous/BinomialLLC-basis_universal.html)

It doesn’t look like it from the code. You can explicitly call this with an empty array to reset.
