Hello,
I think it's a long standing issue which still is present in the latest version. It only affect the bump channel.
It happens if the object has no UVW Tag or if the mesh components aren't properly unwrapped / have no UV coordinates. Projector shader doesn't work too.
The workaround is to unwrap properly the mesh or to choose another projection.

Hi, I am unable to repro this on my side. Is it possible for you to attach a scene with some basic steps which I can follow to reproduce this issue? On my end, it is working fine. Maybe i am missing some important step. Let me know.

Hi Arpit,
Was going to say it seems to be fixed in v13 but no

Scene is attached.
To be clear even with other basic projections mode, Triplanar doesn't seem to fully work. Changing the projection method in the material tag affect the look even if the triplanar is kind of affecting it too. And even in the case of an unwrapped mesh. Here's an example of the effect :

Is this the expected behavior ? Genuinely asking.
