Re: flow map without a brush?
Thanks a lot poopipe Very explaining link indeed. Meanwhile I am trying a bit other approach by painting initial tillable cells structure as a flow map by a brush and then making every directional warp and slope blur I used to deform in sync the initial flow map colors too with a certain color/vector mix. Too bad Substance… -
Re: flow map without a brush?
the sobel filter bit in the curvature_sobel node is a fairly simple example it samples the 8 neighbouring pixels to the current one (thats the kernel) and uses the difference in normal direction to work out how much curvature is happening. this is a fairly clear explanation of how kernel based filters work… -
Re: flow map without a brush?
This is my initial idea how to get flow vector but it has an obvious fault since the rotaton is represented only within180 deg. Same as in a normal map. Perhaps if the normal node would give kind of exr normals representation like in Blender normal AOV it might work better but I am not sure. If somebody have an idea how to… -
Re: flow map without a brush?
Thanks a lot for trying poopipe . I am still not sure I understand how the flow vector/direction is derived here . I tried to build this and it looks like vector warp node mostly. Same as with both vector warp and morph you need proper flow map as a vector input In my texture the streams are just directional warp of some…
