stroke an open spline in Nuke

Howdy,

I need to roto a tentacle/tube that has a consistent thickness. I've been trying to just draw a spline in nuke, and then apply a stroke to it, but haven't had any luck. Googling seems to suggest that other people are trying to develop this in Nuke, but it's not supported.

Does anyone have any advice or experience? Other software available is AE / Mocha Pro.

Thanks!

Unfortunately our roto does not have the ability to stroke a spline yet. There is another options though. You can use the vector paint in the RotoPaint node and just animate the individual points on it. The only issue is that it is a cardinal spline and doesn't have handles like roto does.

Thanks for the reply -

I tried this and it seems to work well enough for the simpler tasks (I am rotoing tentacles, etc), although when drawing a vector paint curve it certainly does create a lot of points that need to be manually deleted. Is there a "simplify curve" technique to reduce the density of points?

I'm also trying to just draw my mask with a rotopaint node, then plug a splineWarp node into that, which seems to do the trick as well.

Thanks again for the suggestion, looking forward to seeing any further developments.

Best,

Matt

No way to do that. I usually just draw it with a mouse instead of a pen so it is a simpler curve and less points to get rid of. Either that or just draw a quick small piece and then move the points to fit and add points where needed. Hopefully in the future we will add the ability to make open splines.
