Houdini Indie and Apprentice » Date in license file of apprentice?

I have installed Houdini 16.0 and using apprentice successfully.
But noticed that the license file contains a date which is approximately after 1 month. Evenif we delete that file and recreate automatically for the same machine by opening apprentice on a different day, the date in the file is set to that same old date. Does it mean that we can't use houdini apprentice after 1 month of license validation?
Thanks

Sorry, forgot to update here:
I used a Python node to apply the transform to each shape in the .abc. Matrix multiplication was needed in the logic to achieve it, i.e. something like transformMatrix * scaleVals * rotateVals * translateVals.. Don't remember the exact code.
Thanks all.

Forgot to update here:
I did it by using a Python node connected to the ununwrap node finally that time. But this needed loading the abc geometry into houdini scene which slows down the artist's work. Then I ended up in doing the uv modification in the alembic file directly by using alembic plugin and cask module, without opening any software.

Opened your hiplc file. But can the transformations of ALL primitives in a single alembic node be done using a SINGLE (python/wrangle/vop?) node connected to the alembic node? This is my need. Otherwise I can do it by connecting xforms to the alembic SOP one-by-one.

Yes, all shapes will come through Alembic node.
Did you mean by using VEXpression? Can you add a simple code to pick a shape/prim from the input Alembic SOP and translate/rotate it using Primitive/Attribute Wrangle node, if possible? I'm new to VEX :-)

I need to create a custom node (digital asset?) in Houdini. It should include multiple Xform SOPs connected one after the other but it's count will varry. This is useful to move individual shapes in an Alembic SOP to different positions by using a single node, other than connecting Xform nodes in chain. Any help?
Thanks

Forgot to add: I have exported the uv details of each shape in some readable format, by using getUvs() and getAssignedUvs() functions of pymel.core. Now I need to import these values to the “old” alembic file (without new uv) opened in Houdini.

I am using Transform SOPs to move each shape in an Alembic SOP. This is easy to do manually in Houdini. But how can I read shapes from Alembic node by using Python API so that I can assign each shape to Group attribute of each Transform SOP?
Thanks

I have an Alembic SOP in Houdini with the abc file it points containing multiple shapes. The uv maps of the shapes were edited in maya later (Assume that the abc file was exported from maya). Now, how can I edit/update the uv map of each shape in the single Alembic SOP in Houdini, without re-exporting from maya to alembic and reloading in Houdini?
If it's by connecting uvunwrap node, how can I modify u and v values of each vertex without using a Python node connected after uvunwrap node? Any sample code?
Thanks

Solved this in a way by connecting Edit SOPs one after another, each using each shape as Group. Then enabled Display/Render for the last one. But is there a better way to reduce the node count in the Tree View?

Oh… It was related to adjusting Display/Render flags of Transform SOPs.
Another issue:
I have multiple Transform SOPs now, each using a specific shape in the Alembic SOP. If I set the Display/Render flags on one, I see it disables it on the others and so only the transform of that particular Transform SOP is considered by neglecting the others' transforms in the display and render. How can we keep the transforms of all Transform SOPs together (since each SOP is used for each primitive's/shape's transform) ?

Hi Jeff,
I used Alembic node to load abc file, then connected it to Transform node. Then played with Primitive Groups, Creat Primitives for, Group, Group Type, etc of both nodes, alongwith modifying Translate values of Transform SOP. But no changes seen in the viewport. Happened the same with Edit SOP also.
Can you attach the simplest .hip file by doing this with single abc file with multiple shapes? I have limitations to share mine here since I am working at office.
Thanks.

Thanks Jeff. I haven't tried this since Houdini won't open in my laptop at home (The error message has been attached here. Any idea?)
The idea is: The imported alembic scene will be an asset (created in maya), mostly a prop or environment (NOT a character). In the shot, this prop will be translated/rotated in maya by animation team later. Now, I need to apply this animation info from maya (which was saved in some format) into the prop's alembic scene opened in Houdini. I know it's simple if the hierarchy is there in the imported alembic scene in Houdini but I hate the full hierarchy! :-) So I have the prop as a single node in Houdini. The problem is the prop might have multiple shapes.

In short, I need to import all shapes in the alembic scene as a single node in Houdini but then transform each shape differently.

My alembic scene has multiple shapes. I want to import it to Houdini as a single node. This is possible by switching off the load hierarchy option when import, or by putting Alembic node in Geometry node and setting filePath of Alembic node to the scene path. But then I need to transform each shape differently. How is it possible?
Thanks.
Thanks.

Hi,
When importing alembic scene to Houdini, all nodes include a reference to the actual alembic scene from which it picks the node by using objectPath parameter it seems. How can we avoid this while loading itself i.e. I want to “cut” this referencing on each node by actually importing all the nodes into Houdini. Is it possible?
Thanks
Jojan
