Wow really cool!
Is it working with Python 3.11 and Houdini 20.5?

Is it possible to assign a shortcut for these icons?

I also switched back to OpenGL

You can try the heavy scene in (Caldera data set from Call of Duty®: Warzone™) from Activision:
https://github.com/Activision/caldera [github.com]

Try to grab the USD file e.g. from:
/caldera/map_source/prefabs/br/wz_vg/mp_wz_island/map_airfield/building_set_a.usd

And see how it perform.

Does .rat image file format support ACEScg?
Is it better to convert the .exr files to .rat before using them with Karma?
Or is it only recommended for other type of images e.g. .jpg?

I am preparing the nodes with Python and use the settings on different nodes and then destroy it.
Is there a way you can do these stuff invisibly without seeing the nodes getting drawing on the Network view?

thank to awesome people at sideFX support the problem was in the HOUDINI_PATH not setup correctly so we fix it and it's gone the error

How did you solve your problem?

I am having this error:

Solved!
The tick on the parm called enable_pathprefix and it has to be set to 0 when disabling.
xxx.parm("enable_pathprefix").set(0)

I have this issue when disabling with Python xxx.parm("pathprefix").disable(True) which is showing the parameter is disabled but the tick still there
And it will export to USD with the prefix

With FBX embedded media you can have the material images with the FBX when importing with Filmbox in Houdini.
Can you read the image path with Python with a custom tool?
A Python script to read from file node pointed to a FBX file.

I am having the same issue even in H20.5, everytime you open the external editor you need to close the file in VSCode to prevent Houdini from crash!

did you use -w like I suggested?

Yes I did, it looks like it's the normal behavior, you need to close the file in VSCode so Houdini can pick it up!

I am having the same issue even in H20.5, everytime you open the external editor you need to close the file in VSCode to prevent Houdini from crash!

20.5 still not stable at all. The objects get despaired from the viewport all the time.
Yesterday I did press "Ctrl+S" to save three times and Houdini crashed and guess what? the file get deleted from harddisk!
"Open recent" showed $hip at the beginning of the path but it's not in the folder anymore! so I was forced to open the last backup file.

Hi, in the hip below there are two approaches you can try:

Thank you so much for the file.

Thank you.
This was my approach but I feel it's insufficient :/

First I assigned the groups and then the attributes.

I have a simple object with 6 uv islands I wanted to give every island an attribute name so I can use that in the shading.
In old Houdini (Partition) node was good solution but it's deprecated now and the recommended node is (Groups from Name) but I didn't know how to use it.

I have (connectivity) node after the object so every uv island has a number.




Any help much appreciated. Thanks

Will Vulkan also be on Mac?

I really hope some staff from Sidefx come across this thread, if only to emphasise that there are people who do model in Houdini - and who want to model in Houdini!

For sure there is tons of artist who want to do modeling in Houdini but the current tools makes it longer to do it.
Of course we wish to stay in the same program and do the work from A to Z in Houdini and not leaving the program just for modeling because when you do so you have to deal with different shortcuts/viewport etc.

And as we all know it's much easier for SideFX to do the tools and much quicker because they know the shortest way but sometime I feel they don't want to do it on purpose :/ and they want to stick with FX only.

I was dreaming of proper modeling tools for Houdini for ages and every new major release I say maybe this year they will do it but I get disappointed :/

Sometimes it's enough with 5 modeling and one basic sculpting tool.

I don't know maybe this is the setup you are after?
I think this is not yet supported by XPU

Believe me sometimes when you have complicated shading network you wish you have such a feature.



At the moment there is no ability to fetch information from a certain network node in Karma H20 material builder.

I think we also need a teleport broadcaster and teleport receiver nodes like in Foundry Mari.
