Hi,
to break weld constraint 'weld' point attribute on a geometry (not constraint) has to have value -1.
I.e. vex code:

if(@Frame>9) i@weld = -1;

in a popwrangle dop should work in your example.

Thank you for the input, your solution is equicalent to just turning the welds off so not really what I am looking for.
I want to break the welds based on the stretch stress etc. It works really well with struts but somehow in tetrahedral it doesn't I am not really sure why.

Hi

I am trying to create a vellum softbody object that falls apart on impact.

I have my pieces with tetconform and tetrahedral constraints. Then add a weld on the edges of the outer shell.
For some reason the combination of tetrahedral and weld points makes the welds unbreakable.

It's important I use tetrahedral for this project.
Any ideas why this might be happening?

Hi

I am having this weird bug where textures in viewport (and OpenGL render) become black and white all of a sudden. Happens after some frames and one it starts doesn’t go back to normal until Houdini restart. I also noticed the alpha has some weird glitches like dancing black pixels.

I am on windows 10, my project is to ACES and I’m loading a bunch of animated textures in exr (50 sequences 1300 frames each) in aces 2065-1 with dwab compression. Just RGBA nothing else.

Anyone ever seen this before? Any fixes?

Ps. I am posting the same topic on all active Houdini hubs, sorry if it’s against the rules.

EDIT: I just noticed - in the display preferences, when the textures are loaded correctly the viewport texture usage is at 5%. When the error occurs it drops to 0%.
