So at this moment I only need to fix: FOR sure: - Hyper Grid - Disco - Embers (For some reason, some particles go down instead of going up...) Not a 100% sure yet: - Waveform (cuz if I'm right it also has an outer line just like the tool brush? I'll have to check tomorrow on Open Brush) - Electricity (I think it moves more open in Open Brush. The beginning and end are like "closed") - Chromatic Wave (I noticed that at the end, the texture has like a small jump cut... Not sure why and not sure if that should be a thing... It's at the really end of the brush just before the geometry stops...) - Petal (I think it looks a bit different not sure yet...) But I think my math is different then yours. But tbf it looks mostly visually the same (The "Thick" brush looks a LITTLE different at the beginning of the brush in my opinion and the "Hull" brushes look different but using the image out of "Open Brush", neither one looks right... But it's rlly subtle). But in your version there is an bug with the pressure size (if I'm right) cuz I had that bug too and I've already fixed it... So we are near the end! 🎉
