Hi there,

first time rigger here, but not for the usual stuff, but for some kind of long and open straw that I want to animate the opening and closing.

Normally this wouldn't be a problem thanks to the nice tutorials I have found, but I can't get the weight map getting through all points in the Y direction. I have tried experimenting with a simple tall wall and the best I could come up with is to duplicate my rig along the y axis so that the influence is equal. That seems to work OKish, but if there is a better way I would like to know Having one clean rig would be way easier to handle.

Me again, I think I may have found a more elegant solution with the Paint Capture Layer Node.
Two things bother me though (+2 more ):
1. One time only I managed to paint a region with strg+middle mouse, I cannot reproduce it.
2. If I paint the weigh maps like I want, they only display when I enter the capture layer node again. If I'm out in the bone-deform node it shows the old map again but works correctly. Is there a way to have the new map displayed?
3. Is there a way to create the map by selecting the points/vertices from the top view and bind them to a bone? This would make things a lot easier.
4. Is there a command to smooth the adjacent edges?

thanks for your help (hope so)

and post back with any other questions you have, or post the hip file and we can figure it out together.

Hi, I did, at least the first hour It's a very nice tutorial I will have top watch completely. But right now I'm in a little of a hurry. I could have done it in Blender, but I thought why not give it a chance with Houdini, has to happen someday

I think I have it quite ok now. I used the greatness of Houdini for it. I first squashed the object by a y factor of 0.02 first, so that the capture region perfectly fit the object. Then, after the capturing process, I simply added a new transform node and stretched the result by a factor of 200 and I got a perfect result after a little tweaking of the weight parameters.

After this project I will surely finish the tutorial and hopefully be able to answer the questions myself, and if not, will ask again
