OSL Shader Blur?

[ceen]

Hi,

I tried to feed a 3rd party OSL Shader into the Gaussian Blur OSL code provided by Octane without success. Bake node in between the two OSL nodes did not help. Is there a simple blur code for Octane OSL or how can we blur the OSL input with the gaussian code? Thx!

Hi,
you need to have a Projection pin in the OSL shader, in this way you can add a Projection node to it, and set it to "OSL delayed UV" mode, to enable the Gaussian Blur OSL node:

Thank you! You mean by right click on OSL node and add projection pin? Sadly that frezes Octane here. Or by code?

Yes, the OSL node must have the Projection pin in the code.

Which OSL script are you trying to use exactly?

ciao,

Hi,

this one:

Could you share a screenshot of the Code for the projection pin? I read the OSL docmuentation, but I always get errors

Hi,
I had a look at the OSL shader, but since it involves geometry, it cannot work with gaussian-blur.osl node, even with correct projection.

Anyway, you can obtain the same effect by using an Octane Falloff node in Normal vs vector 90deg mode:

And use an Octane Gradient to define the blurriness you want:
