Sorry for reviving the old thread but this might help someone in the future.

Besides using Dopesheet, it can be done through a channel list(s).

Docs: https://www.sidefx.com/docs/houdini/ref/panes/chanlist.html#modify [www.sidefx.com]

To Mute/unmute individual channels from the parameter editor by RMB clicking the parameter name, and choosing Channels ▸ Mute Channel or Unmute Channel.

Or CTRL+Mto Mute or CTRL+SHIFT+Mto Unmute.

Unmuted:

I don't have this option! I am using H20

one thing I have noticed with RS as a delegate is that Motion Blur is automatically on, I can't turn it off

Did you try to enable "Instantaneous Shutter" for that?

Solaris and Karma » Karma XPU feels really slow!

Hi guys

Sorry to hear you've found XPU slower than expected. From our experience, there are some parts of XPU that are indeed slower than other renderers (eg lots of refraction, indirect lighting, etc...), but others where it is fast/faster (eg hair/fur). So it really depends on the scene. I notice the two examples with the most issue here are refraction-heavy (ie glass).

Plan heading forward:

We'll continue to look at refraction/glass to improve performance. I've just now committed an optimization (~15% speed increase) which will show up in the daily builds.
Adaptive sampling is a big one that XPU currently does not have, but we plan to get onto that soon. We expect it to give a sizeable speed boost.
We'll also be looking into the NVidia SER feature very soon, so we'll keep you posted on that too.

In short, we're continuing to actively improve all aspects of XPU, including performance, so keep an eye on the daily builds.
Thanks for the tests and feedback.

Disabling Embree clocks in at 29:06 which I guess is expected.
Good to know XPU is giving expected gains with both CPU and GPU running. I've heard other renderers tend to actually slow down when in "XPU" mode

Great news!

Please have a look into the new Intel Open Path Guiding Library as well: Intel® Open PGL https://github.com/OpenPathGuidingLibrary/openpgl [github.com]

Solaris and Karma » No keyframe on timeline when creating keys with Python


jomaro: 102 posts; Offline

2023年11月2日 03:37:41

It turned out it's not a bug, I fixed it with the help of the great SideFX team, Thank you.
Here is the solution if anyone looking for similar case in the future:

SideFX message:

From our developers
For the keyframes to be visible on the timeline, parms need to be added to the channel list.
Creating a keyframe from the UI usually sets the autoscope flag on the parameter, based on a user animation preference. This isn't done automatically from hou.Parm.setKeyframe.

Call:

hou.Parm.setAutoScope(True)
hou.Parm.setAutoSelect(True)
hou.Parm.setScope(True)
hou.Parm.setSelect(True)

before adding the keyframe.

Solaris and Karma » No keyframe on timeline when creating keys with Python

I am trying to set some keys on a LOP Camera with Python.
The motion is there but there is no keys on the timeline!

import hou
myCam = hou.node("/stage").createNode("camera",("test"))

for iter in range(1, 90):
        myVal = hou.Keyframe()
        rotatex = myCam.parm("ry")
        myVal.setFrame(iter)
        myVal.setValue(iter)
        rotatex.setKeyframe(myVal)

Am I missing something?

Is it possible of referencing a name from previous node and add a string with it so it will change whatever node name upstream will be connected.

In this example the node transform will change to p03_transform

i wonder how out-of-core will work , because in kerma xpu lecture that was last month he said that one of the device can fail when outofmemory but when i think about it the idea of out-of-core its to use RAM (switch data between RAM and vRAM like redshift) ,
soo anyone know how it will work in h20?

They mentioned this in the Houdini 20 Sneak Peek Full Feature List [www.sidefx.com]
• Robust multi-GPU architecture with failsafe out-of-core capabilities

We have to wait till next week to find out.

thanks brians, that's good to know, however such "Light Source" doesn't seem to show up in Light Linker or Light Mixer also can we tag lights and objects for LPE's and would such "Light Source" lpe tag work as a light tag?

Hi Tomas
Those features are not supported yet. Once Pixar have done the work necessary for Hydra to support geometry-lights, then we will be able to move forward on them. We don't have a firm date on when that'll be unfortunately, at this stage it will not be in 18.5 at least.
Thanks

Is this limitation still present?
