Prefer KTX is not working when running on the application

When applying compressed texture on the 3D model, assign a normal (JPG/PNG) type to the object's diffuse map and set the Prefer KTX option.

When running it with preview and running on the application, the compressed texture is used instead of JPG/PNGs.

However, currently, when running on the application, it looks for the original diffuse map rather than using compressed texture so the texture is not shown.
