3D procedural textures artefact working with UDIM's

Question

hey there!i'm trying to use 3D procedural noises (like perlin noise for example) as textures in generator like mask editor. i'm working with UDIM's and i'm haveing weird artefacts. if i'm using it as a mask where you can choose a projectin there is an option "fill (match per uv tile)" which helps solve the issue but there is no such option when you put it as texture in generator

From @evgeniy evstratiy in another thread:"i spent few hours but i found out the reason of this. turned out that you should noise scale parameter and do not touch generator's texture tile size"

Sorry for necroing this post, but this is basically the only response I have found that addresses this issue. Unfortunately the proposed solution doesn't change anything for me. It appears to be that any 3d noise when using a triplanar projection displays the 2d UVs of the mesh you're painting as a mask... though now writing that out I believe I have found the solution to my problem :/.

Using 3d noise with a triplanar projection causes a bug. If you set the 3d noise to use "uv projection" or "fill", the issue goes away and the noise is still 3d. Cheers y'all, hopefully this is helpful to someone else.
