Pin KineFX Ragdoll? July 31, 2022, 9:22 a.m.

Playing with the KineFX setup.

Using an FBX character import node.

I'd like to pin a joint to an animated external point/geo while running a ragdoll simulation.
Essentially a character with a guide wire the lifts it up/down while passed out.

I see the "external constraints" in the ragdoll constraints node, but it doesn't seem to do anything when I pass external (packed) geometry into it.

Any ideas?


No Density from ConvertVDB Node? May 17, 2022, 7:02 p.m.

Rendering in Houdini with an engine that needs VDBs to render pyro sims.

I seem to recall this just meant passing the bgeo sequence into a convertVDB node and then another filecache node to save it?

However, when I inspect my convertVDB node I see my density field is 0,0,0 (as opposed to having density values when inspecting the file node loading my bgeo sequence!). So, nothing gets rendered.

I've tried using *, @name=density, and just leaving the group field empty.
My other fields are getting there (temperature, flame, etc) just not density!

Am I missing something? Using Houdini 19.0.531


Trying to Follow Tim's "Trendy Transitions" Tutorial... Oct. 7, 2021, 2:45 p.m.

Still no luck!

Essentially, here's what I'm trying to do...

1. Use a voronoi fracture node to... well fracture geometry.
2. Assemble node to pack the pieces.
3. Create another piece of geo with a pscale of "0"
4. Attribute Transfer to shift pscale from 1 to 0 based on distance
5. Transform pieces node to actually transform the packed pieces.

Am I completely off base here?! Is there a better way?
