I've recently switched my envrionment from Win10 to macOS Big Sur, and noticed that Scene Viewer looks too laggy when I applied materials with a custom viewport shader to geometries on a scene.
I tried to figure out what becomes bottleneck, but even if I used the built-in glsl code that we can see on the Code tab of the default GLSL Shader asset, it somehow makes the viewport very slow in proportion to vertice counts of the geometry.
Does anyone know how to handle to this issue? ...or is it a known bug on mac?

Technical Discussion » How to retrieve the position of point from snappingRay()

Referring to the below example, I can figure out the point index that the mouse cursor is currently snapping to, but does anyone know how to retrieve its position using the dictionary returned from `UIEvents.snappingRay()`?

Technical Discussion » Scene View occasionally keeps hidden geometries showing

I've worried about buggy Scene View behavior that geometries which are just hidden are still visible.
The bug sometimes occurs when moving up/down a network level or toggling the display flag of a SOP/OBJ node.
Is there any way to refresh all of the geometries' visibility other than recreating a new Scene View pane?

Technical Discussion » Audio playback on the viewport slightly delays

Does anyone know have the same issue or know how to solve it? MPlay has much more latency (nearly 0.3 sec!) and I cannot rely on the preview when making animation by hand anymore. It occurs on both mac and windows even if I reset all of the settings.
some of Houdinists suggest me not to use it for manual animation which is sensitive to audio syncing and otherwise it'd be better to try audio-reactive approaches w/ CHOPs. Yet I think precise playback is a quite basic feature that all of the software for video production should be equipped.

Houdini packages would be useful than traditional houdini.env.

Is it possible to switch the value of environment variable with something like if-statement?
I am now syncing houdini.env over multiple PCs including Windows and macOS, and wondering the way to load additional plugins depend on the value of HOUDINI_OS.
Though I tried to write some scripts in $HOUDINI_PATH/scripts/pythonrc.py, it would not work as the process to load plugins seems to be done before pythonrc.py is executed.

if hou.getenv("HOUDINI_ENV") is "Windows: hou.putenv("HOUDINI_OTLSCAN_PATH", "%s;<THE PATH TO PLUGINS>" % hou.getenv("HOUDINI_OTLSCAN_PATH"))

How can I add a keyframe to only one channel hovering with the mouse in Animation Editor?
In default, alt-click on a curve adds keyframes to all of the displayed channels simultaneously.

I tried all of the methods and realized Redshift was the fastest in my environment.
Thank you so much for your advice!

As I am using Houdini for flat-look motion graphics instead of Cinema4D, I wonder if there are smarter settings on Mantra (perhaps 3rd party renderers) to render the scene without any shading quickly.
Would someone tell me the idea for that?

Thank you for your quick reply!
It works for me when I set the cache/render range over multiple frames as you said.

When I render geometry caches or images, everything appears to be done in the background and any dialog is not shown.
How can I fix the issue?
