tex2Dlod() not working when using Metal on iOS

For me tex2Dlod() is not working when using Metal on iOS. (result is 0).
Anyone else with that problem?

 

Figured out that tex2lod still works with metal but it does not work with the mip maps of render textures.

 

I've been having issues with tex2Dlod() on metal also - I was using a texture for reading a heightmap that I could pan over a surface, but unfortunately nothing I've done has stopped the surface from "tearing" as polygons seem to be getting different values for the same position.

EDIT: Typically shortly after I post this I literally tripped over a fix for my problem: It seemed to be caused by the aniso level on the texture. Hopefully that might help you!

 

For those finding the topic via google: The maximum mipmap level is 3 for compressed textures on iOS.
