For some reason, I cannot use the `jointcapturepaint` node tools without getting bombarded with error messages and erratic behaviors ... the error message pops up immediately after clicking the node or the handles button.

Traceback (most recent call last):

If you hit "OK", another one follows:

Sometimes that is followed by a much simpler error message box exclaiming a Python script error.

After dismissing the error messages, the paintbrush will often show up, but it behaves wildly. It's prone to disappear and won't come back unless I hold alt and zoom in and then out (super weird). Crazy stuff also starts happening to the rig/skin:


Nothing special about the node network either ... this seems to occur with every character I've tried, every scene, even a fresh one with 3rd party models downloaded from online and directly wiring things up.

Painting weights is really difficult due to these erratic behaviors. It doesn't paint correctly. It seems to keep switching to "Smooth" operation of its own volition, and using Ctrl/Shift modifier keys doesn't have consistent behavior. Sometimes it will erase, sometimes smooth, I have no clue what's going on.

Would really appreciate some help with this. I have always hated painted skin weights and had bad experiences with it in every software. At least this has been the least bad experience, despite the crazy buggery. But still far from enjoyable or pleasant, haha. It's honestly a major game dev show-stopper :-(

Before I make an official bug report about this, I wanted to check and make sure that I am not doing something wrong or overlooking something obvious, and see if anyone knows a work-around or alternative so I can get this work done!

Regards,

Aaron

(EDIT: Relocating the rigpose node didn't help, same thing happened ...)

Is the problem the location/order of the `rigpose` node?


Should it be after the paint node? If so, maybe it was my fault all along :S

Can you try the latest production build? If it's still reproducing there, then please log a bug with a sample hip file along with steps to reproduce using the sample hip file: https://www.sidefx.com/bugs/#/create/ [www.sidefx.com]

I've reported this bug quite a while ago and they said it was fixed in Houdini 20.0.653.

Yes, I will! I've found even more trouble, like it tears holes in the mesh also sometimes :S

I'm getting it in 20.0.650 but I will try updating to latest prod build and see what happens ... fingers crossed!

In .653 I reloaded the .hip scene file and this time no error message boxes and the paint brush appeared on the first try, but still got a hole cut in my character's hand and trying to smooth joint weights of finger cut even more faces out lol ... but this scene may be (and probably is) corrupted at this point so I need to retry it fresh and have to forfeit those dull hours of hard and tedious work

I'll post updates on how things go re-trying the process in the latest prod (.653)

This is appending a NEW Joint Capture Paint on top of your old one?

Generally speaking when you have corrupted capture data like this you can fix it with:

1. First stash it with Stash SOP so you have no dependency
2. Capture Correct SOP
3. Transfer the corrected data back to your upstream mesh with Attribute Copy SOP

Of course it's not guaranteed.
