Bevel Smooth Dilation - noisy result.

[dimwalker]

Hello, folks.

I want to dilate a pattern gradually using Bevel Smooth's Dilation and getting lots of artifacts. Have a couple worakarounds (more like  hacks really), but would still like to know if that's intended behavior or am I doing it wrong.

 

Attaching mask and source maps so you can test it out. Distance is Gradient Linear 1.

Hello! 

You can start by setting 'Mask threshold' to 1.0 to get rid of the artifacts, then playing around with 'Mask smoothness' to tidy things up to your liking.

Please let me know if that helped.

Best regards.

Yes, thank you!

Though I must admit I still don't understand what Mask Threshold value actually does here. Both inputs only have black and white pixels, usually there would be nothing to threshold without nuking whole image.

Indeed, you reasoning makes sense. The Mask Smoothness parameter controls the intensity of blurring applied to the Mask Input before sampling it to run its algorithms. The threshold is applied on that blurred version. Therefore, the Mask Threshold parameter will have more of an effective range as Mask Smoothness increases.

I hope this makes sense. Let me know if you have any other questions!
