Python callback to run every time any HDA parameter change Feb. 19, 2026, 3:19 p.m.

Python callback to run every time any HDA parameter change Feb. 18, 2026, 9:22 p.m.

Hello,
I am trying to find the best way to hook up a python callback to write the data from my HDA menu into a json file (a dictionary that stores all the data)

At the moment I have added for each parameter the same python callback in the callback script section:

hou.phm().export_json(kwargs)

although I find this a little, well, brutal???

Would there be a better way to do this you reckon?

Any advice would be great

Many thanks

Warp geometry effect via curve tangent transfer May 6, 2025, 3:08 a.m.

Hey guys,
was trying to deform a grid using the transferred tangent from points of a curve to create a sort of warp effect in the proximity of an animated point traveling along the curve....this works well on a grid when the line is perfectly straight along Z axis, if I rotate the plane and the curve a little any addition to P.z does not pull actually correctly tangentially to the curve

Any suggestion on how to potentially solve this issue?
