Improve intertwine for gradients and effects
Improve intertwine to allow gradients along a path before intertwine is made, then fully implement drop shadows to overlap intertwined segments. See attachment explaining workaround I produced along with high res rasterization to show where result is better than Illustrator display on monitor.
Now I see what you meant: Make the gradient "within stroke," then create mesh, then make gradient applied across the stroke. That works and it saves time. Thanks!
Egor, Thanks for your comments. Yes, I see the mesh with expansion. But I don't follow "If you change the mode back to 'within'... Where am I selecting "within" ?
Yep, makes total sense!
I can see what is happening here. When we make the gradient on strokes flow along or across, Ai secretly treats them as gradient meshes, that only look like strokes (and if you expand them, this is what you will get). And Intertwine seems to not know it should still detect intersections based on strokes! But indeed, if you change the mode back to 'within', then make them intertwine (which now works!) and then change the mode back to 'across' — there we have it, it works. So it CAN be fixed.
As for the shadows... this would be technically almost impossible, I think. After building the masks needed yourself, you realize what it needs to calculate... But sure, voted.
Original Ai file is 35MB = too large to upload so jpeg of it is here to review.
