This is what the gaussian blur kernel from Wikipedia looks like: Apr 23, 2024 · Options #. That works for all separable filters, not just for blur (not all filters are separable, but many are, and some are "as good as"). Most people optimize gaussian blur by splitting it into horizontal and vertical pass, but in this case mesh geometry is rendered for each pass, which may outweight the benefits depending on multiple factors, such as triangle count and kernel size. I don’t know what’s happening on the edges, lol. My idea is to create some kind of temporal blur using a shadergraph, in full screen pass renderer (available with URP).
