Gaussian blur definition

WebA Gaussian blur is implemented by convolving an image by a Gaussian distribution. Other blurs are generally implemented by convolving the image by other distributions. The simplest blur is the box blur, and it uses the … WebI would also call that 'lacking' a feature. As in, this feature doesnt exist in the tool. That's kind of the definition of lacking. I'm not finding live brush water colors to look anything like gaussian blur. If someone does know a good simulation of a guassian blur in Fresco, please share. I'm still learning the tool.
