Release Notes
=============================================
RELEASE 2023.1.2.2
=============================================
* PLUGIN FEATURES AND FIXES:
- Added Houdini 20.0.625 plugin builds.
- Fixed "The Instance node "setup" is referencing a not available object" error.
- Fixed Packed Geo Instance Crash with Motion Blur.
- Fixed errors while reloading scene in some cases.
- Support custom attributes for Packed geo instancing.
Existing scene needs to recreate Octane ObjParms by "-ObjParms" and "+ObjParms" to have the new Custom Attributes parameter when Packed Geo Instancing is enabled.
Below is an example of the setup of using this Custom Attributes parameter.


The material setup:


Common Issues and Solutions
- If the plugin doesn't work at all, set HOUDINI_DSO_ERROR = 2 in houdini.env and check for messages in the terminal.
- If you're missing libglut.so.3, install the freeglut package.
- If you are having any issues with the Deadline - please submit a support ticket to the AWS.

Happy rendering,
Your OTOY Team

Custom attributes on instances is a such a welcome feature but custom attributes shouldn't be hidden when Packed Geo Instancing is turned off since it works with other methods of instancing. (e.g. instancepath attribute and instance node)

When using instancepath, instances wont render if Packed Geo Instancing is enabled so turning it on to add custom attributes then turning it off to render is tedious.
It works when using instance node but you have to manually add the object parameters. In this method, it doesn't matter if Packed Geo Instancing is turned on or off.

I have attached a sample file if anyone needs it.
Cheers.

Hi galleon27, thank you very much for pointing out this. It will be fixed in the next release.

Hey there,

I'm having a problem with the Motion Blur whenever I use texture displacement in my material.
Is this a known bug? Once I delete the displacement texture, Motion Blur works as intended.

Thank you for your help!

Hi, please can you PM me that portion of the scene to check out. Thanks!

Thanks!

What is the workflow for importing float custom instance attributes?

Hi are you still having issue with this? It should work in the same way as vector.

Auto bump map in vertex displacement is broken. Works fine with images, doesn't work with noises. Works just fine in standalone.

Thanks for reporting this and giving a sample scene - it is appreciated!
We will investigate, for now you could add a bake to texture node in between the noise and displacement.

Looking now, this seems like it is an issue in Standalone 2023.1 but not 2024.1 alpha with the Noise + projection: XYZ to UVW
Add a UV Mesh Projection onto the Noise node and it will work.
