_fluffy Posted November 11, 2022 Share Posted November 11, 2022 The Procedural Texture Generator is pretty great for a lot of things, but something it can't do, as far as I can tell, is make computations on a source pixel based on its neighboring source pixels. If there were a way to index other pixels by offset within the texture function, Procedural Texture Generator becomes an incredibly powerful tool for things like generating normal maps from height maps and applying convolutions. On that note, it would also be great if lookups could come with a convolution kernel (to apply a transfer function to a group of pixels at once). In particular I'd love to be able to edit a normal map from Affinity Photo by drawing into a height map and then have the new normal map generated on-the-fly as essentially an adjustment layer.
