Hey there,

This is likely a known Houdini bug that causes packages to interfere with each other. You'll need to update to build 18.5.415 or later, or roll back to 18.5.351.

Yes! There should be a step parameter on MOPs Randomize that does exactly this. If you don't see it, you might need to update to a newer Experimental build... you can do this quickly with the Updater shelf tool.

你好! I've patched this in the latest Experimental build. You can use the MOPs Updater shelf tool to automatically update, or download the new build here: https://github.com/toadstorm/MOPS/releases/tag/v1.2.7e The new build contains MOPs Aim 1.1. There is a new parameter called "Match By Attribute" wh...

The easiest way to handle this is to unpack your instances, do a UV projection onto them, then repack as packed fragments. MOPs Convert can handle the repacking for you. This will allow each instance to behave as a packed primitive, but retain its unique UV attributes.

This is a known bug in 18.5... they changed the VEX signature for primuv_convert(). If you download the latest Experimental build of MOPs, 1.2.4e as of this writing, the bug should be fixed.

Okay, let me clarify the installation steps... The MOPs.json package file goes into your packages directory, which is /houdini18.0/packages as you mentioned. What you need to do next is edit MOPs.json in a text editor, and adjust the value of the "MOPS" variable inside from the default path that is ...

Redshift doesn't consider packed primitives as actual instances by default... you have to tell it to read them as instances instead of as regular geometry. The toggle you're looking for is on the Geometry container, under Redshift OBJ > Settings > Instancing > Instance SOP Level Packed Primitives. T...

That's quite a story! I've had nice conversations with one or two of the Maxon folk before but admittedly I know next to nothing about Cinema 4D... that was more Moritz' forte. I'm a long-time Maya guy that switched over to Houdini (as much as possible) years ago. Anyways, regarding packing... any g...

Yeah, that was a typo in the MOPs Updater script this time around. It's just a tab versus spaces issue... you could patch it yourself by converting tabs to spaces on the offending line. Otherwise, for the next release you'll have to install manually. Sorry about that!
