Setting up karma to render on a extra PC April 8, 2026, 5:39 a.m.

One pretty easy solution is Deadline. (https://docs.thinkboxsoftware.com/products/deadline/10.4/1_User%20Manual/manual/index-introduction-to-deadline.html) It is free nowadays for less the x computers and it is not too complicated to setup and has a good feature-set imho.

Houdini MCP PySide2 or 6 April 7, 2026, 4:25 p.m.

I'm experimenting a bit with MCP and Claude in H21.0.761 and got the MCP server running, using Anaconda instead of uv that is suggested in the github description.

In order for things to work i needed to change the PySide call in server.py from this:
from PySide2 import QtWidgets, QtCore to this:
from PySide6 import QtWidgets, QtCore

I can however imagine that the Qt6 is different from Qt5 that I understood Houdini used internally and this Houdini is 3.11 and PySide2 is max 3.10 iirc.
Would I run into UI issues with this easy fix or should i create a proper Houdini safe environment and if so what should I take into consideration?

Looking forward to any input on this.

Cheers,
Rudi

Point cloud in karma shader March 31, 2026, 6:17 a.m.

You look up points and their attributes from .bgeo/.pc files with Karma Point Cloud Read (kma_pcread) [www.sidefx.com]. Also works in XPU 🍪
Thanks, I'll try that. Nice! I was typing "cloud" or "pc" but that did not bring anything up, so it's just point, no cloud now :-) This looks like exactly what I need, tnx a lot! Appreciate it.
