Shared sample streched

Hello,

I have too many textures in my landscape material, so I would like to use “shared sampler”. With a regular sampler, everything is fine.

Shared : Clamp and share : Wrap give this result :

Does anyone know what I’m doing wrong ?
Thanks !

Found a solution. Samplers in “shared : wrap” mode

then :
