Generally this error happens if you're trying to use a Python 3 build of Houdini with a Python 2 version of MOPs+, or vice versa. Check the Downloads page and grab the latest MOPs+ build for your particular Houdini... Python 3 builds are now labeled as such.

MOPs and MOPs+ need different environment keys... you're going to effectively overwrite them here. The sample JSON file that comes with each should be using different keys: MOPs defines a variable called $MOPS, and MOPs Plus defines a variable called $MOPSPLUS. I'd recommend starting from the includ...

I meant the actual JSON text. You'd have one package for MOPs, and another for MOPs Plus, and another for Renderman, Arnold, etc. Arnold will install correctly by itself, but it still writes to the houdini.env file. Once you start getting other plugins involved, that's where things can start to go a...

Can you post your package file contents? That'd be the most important info. The order of operations makes sense if you're using the .env method... then you have to start worrying about how your various HOUDINI_PATH entries are appended to each other. Packages sidestep that issue, which is why they t...

Can you please provide me the following information:

* The contents of the package files you're using, for both MOPs and MOPs Plus
* The installation paths where both versions of MOPs are extracted to
* The locations of the package files on disk

Thanks!

This feature has been added to the `henry_dev` branch on GitHub. I'll fold this update into the next Experimental build.

It's not built-in at the moment but I can add it.

In the meantime, if you create a circular curve of the same radius and position as your instancer, you could use the randomization controls on MOPs Move Along Spline to jitter the positions along the circle.

Nope, you're not overlooking anything... looks like mesh interpolation isn't working in this mode. I'll patch this up, but in the meantime the best solution is to uncheck "Enable Template Interpolation".

Today's build adds drag-drop reordering to the Attribute Mapper. Let me know how it works for you!

If you notice this bug happening in a clean scene, please let me know. I'll keep working on the reordering thing.

Thanks for purchasing, and I'm happy you're enjoying MOPs!
