I just do as the document in https://developer.apple.com/documentation/shadergraph/realitykit/cube-image-(realitykit)

I have a .ktx file, and use CubeImage node to load it, then Convert node, but it shows black. I check it on my Vision Pro, it's still black, I don't know why? Is it something wrong? 截屏2024-10-17 10.36.33.png

ps: I also use Image node to load .ktx file, it shows one image, so I belive .ktx file is right. I alse checked it on Vision Pro. 截屏2024-10-17 10.44.29.png

Hi @XanderXu

Your shader looks correct to me, so I'm guessing there's an issue with the cube map .ktx file.

Could you try generating your .ktx file with the xcrun realitytool image --generate-cube-map command in your terminal? You can run xcrun realitytool image --help to see more information on how to use the --generate-cube-map command.

Let me know if you run into any issues.
