Blur node

[SSmolak]

Hi, is there other way to blur noise node than using Baking Texture with low resolution ? I see that there is OSL Blur node but it completely doesn't work.

Hi,
please have a look at here:

Thank you, so this blur node doesn't work with standard built-in Octane noise nodes ( even using Projection pin ) but only with custom OSL's ?

EDIT : ok I know why it didn't work for me even using Delayed OSL Projection. Because I had blur node only for bump pin and not for albedo too. The question is how to use Delayed UV Projection but without OSL node betweeen Noise and Albedo ?

Also this node is crazy slow...

Can you share an example scene + screenshots, the issue is not clear, sorry

About speed, try to decrease the Interactions at two:

I mean this situation where OSL Delayed UV projection works fine for blur node on bump pin but how about others like Albedo ? I tried different OSL nodes here without success.

EDIT : Also I noticed and reported this weeks ago that blur channel is much stronger using projections other than UV. UV projections have like 25% power of other projections :

UV vs Box Projection on Bump channel :

Hi,
as you can see from my screenshot, it works correctly in Diffuse/Albedo pin, try to place the gaussianBlur just after the Noise, and before the three Gradient nodes.

About Bump power, try to have the same scale, or it is difficult to compare.
In Box mode the scale is in meters.

Problem is from power not scale. UV projection cause much less power than other projections on bump channel. I will make video soon.

Yes but I mean that OSL Blur only for bump and Albedo clear noise only. This not work for one noise node because there is need another OSL node between noise and albedo that will support OSL Delayed Projection.

This is indeed a pretty big problem when using for instance Triplanar Mapping for bump mapping and has been brought up several times but without any real solutions other than "don't scale down so much" which makes triplanar useless for certain bump maps on small objects modeled in real world scale. I for one would LOVE to see this fixed somehow.
See for instance this thread from last year:
viewtopic.php?f=30&t=77459

I have had some success by raising the gamma of the bump map to around 3 with a color correction node, but I mean, it would certainly be preferable to not have to jump through weird hoops to make triplanar/box mapping work.
