SP Blur filter UV islands on mask

[LaurMan]

came across this issue with substance painter when trying to apply a blur filter.
Substance is blurring it per UV, what results in a very ugly result and basically makes the blur filter worthless.

is there any workaround that?

It looks that someone way back asked about it, in the time when it was not owned by Adobe, but the post has disappeared

Thanks for the help

Anyone from Adobe can help?

I have the same problem and woud appreciate if anyone has a workaround.

I have the same problem and also friends of mine.

[Eszenyi261166410a01]

Yeah I got the same issue. Adobe should address this issue asap as it practically makes blur useless.

[LaurMan]

still nothing from Adobe 😞

Adobe, please respond. If there is no solution to using the blur filter across UV islands, let us know. Maybe there is a workaround.

Hi Patrick, Hello everyone,

Currently, the blur filter is simply the blur node from Substance 3D Designer. Therefore, this filter has effect on the 2D view (so only the UV islands), and this is what creates the seams. As an artist too, I know how bothering these blur seams can be.

One workaround would be to blur your layer as usual, add on top of it a paint layer, set its blending mode to passthrough and paint with the Smudge blur the seams.

You could also try to make your own blur filter with Substance 3D Designer, or directly buy the 3D blur from the artist Victoria Holland. To be clear, this is a filter made by the community, I never tried it, and I don't know anything about its quality, but the comments seems good. My only advise if you do buy a custom filter: don't overuse it.

From experience, these filter are rarely optimized and can drop down your project performances.

Best regards,

Thank you for the insight, Cyril.

Will give it a go the next chance I get!

These are great tips thanks! Any chance Substance Painter will have its own inbuilt solution to this problem (=better blur filter)? Also worth mentioning that there are other nodes in it still working only in 2D space like some noise textures. Reworking those as well would be paradise! UDIM is really a thing nowadays. 

Anyway appreciate your help!

We currently don't have any plan on this regard. I'll share this thread with the rest of the team.

Appreciate it, thanks.

Smudging is an obvious and lazy answer. It can be a temporary fix to a software's shortcomings, but this should not be considered a valid workflow. Smudging looks inconsistent as our human hand isn't designed to be a perfect smudge brush stroker and having to find and blur all areas every time we use blur filters, which everyone constantly uses, is just not acceptable. Get this sorted Adobe, ASAP!

Just pay this add-on dev to be able to add that feature into base substance painter: https://www.artstation.com/artwork/DARaaO
