The texture array displays white

  • I don’t understand why the texture is white.

  • Also, can texture arrays be called using glTexcoord？

How are you accessing the texture? Array textures can only be used via shaders, not the fixed-function pipeline.

  • Thank you. I think I know why. I used a fixed-function pipeline.
