On mobile, I use a lot of images, so I want to use texture compression to convert files like PNG or JPG into KTX, but I don’t know how to use it?Loading directly in the material did not work

Thank you very much for your answer, but in the environment of the React project, Engine does not have setTextureFormatToUse function, do you need to install other dependent environments? ![q90g](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/2X/1/1a0659d5806c2c9cb3cbe4b5ab0de009a974270e.jpeg)

You should upgrade to our latest preview for 4.2 to have the function available in babylon.
