Please add Blur node.

+1

There are some tricks you can play with UV space and such, but it would be nice to have a basic multiple choice set of blurs in one node; linear, box, lens, radial, etc. I don't know how complicated it would be to add them to the current GausianBlur node. Now I'll have to go poke around in the OSL world to see what might be kluged together...

Blur is very important for bumps. I know about the new Octane Beta 2023 bump feature. It doing good job but not as good as real blur.

At the moment I found that Baking Node with low res can simulate this but quality is not good.

Does the GausianBlurOSL node not work for your bump maps? I used it all the time while building shaders, but for really large textures I'll usually bake it out if possible to simplify and speed up the network.

GausianBlurOSL is the most slowest node.

Also it needs delayed OSL uv projection so the same image can't be used for other channels.

EDIT : but with this attached simple OSL it can be done. It just add plain OSL UV coordinates to texture without changing it so it can be used with delayed UV Projection. So now other channels will not be affected by OSL blur node :

Yes, that's why I usually bake it out once I find the look I want.

Baking whole big elevation texture is wasting vram for me.
