Triplanar projection missing on some filters/generators?

Question

Hi everyone, it's been a while since i started wondering why there's no triplanar projection option for some filters like "Blur Slope" or generators like "Dripping Rust". I love triplanar projection, most of the times is definitely a game changer, but when i come to use it in conjunction with those two filters (which i often like to adopt) i always have to tweak with a painting layer on top of it to correct the visible seams appearing on the textures, which can be really tedious depending on the asset i'm texturing and the level of details.
Is it possibly me not knowing how to fix it or is it actually a missing "feature"? If so, how come has it not been implemented and doesn't work like with other generators like "Dirt" for example?
Thanks to whoever will have an answer or will be able to help 🙂

Hello @Mark - Da_Drood,

Don't worry, this is a great excuse!

Those Filters / Generators (like the Blur slope) are often nodes from Substance 3D Designer. These nodes work on 2D images, and inside Substance Painter, in order to work properly, they affect the 2D view, meaning the UVs. The UV islands create a discontinuity on the effect, creating the visible seams.

Unfortunately, this is the expected behavior and there are currently no plans to share on this regard.

Cordially,

I assume there's actually no explanation for this? It would be awesome if this could be implemented in one of the future patches though. Or if there's a logic behind the fact that some filters/generators can't apply triplanar projection i would like to understand why.
(also yes, i needed an excuse to bring back up to page 1 this topic *-*)
