Missing textures in 1.16 for Purebdcraft?

Hello textures such as andesite, diorite, granite and basalt and potentially more are default textures

There's not enough information here to help you.

It's pretty unlikely anything is missing or we'd have a lot more bug reports for missing textures.

Are you sure you're on MC1.16?
Can you post a screenshot of your resourcepack screen?
How exactly did you install the pack?
