Without having Houdini in front of me, there's one thing I'd check for. Since you mentioned you merged two Instancers together... you'll probably need to regenerate the i@id attribute to prevent duplicates. You can use the Enumerate SOP or a point wrangle with the expression i@id=@ptnum to do this. ...

Yeah, embedded nodes can be unlocked and edited like any other HDAs. It's generally not something you want to lean on too hard, only because then your definitions might not be the same from scene to scene and this could be a pain to deal with later on. This doesn't apply to MOPs Plus nodes btw... th...

You would need to embed the MOPs node definitions into your hip files if you wanted to submit them to a farm that doesn't have MOPs.

If you move that Blast to after the second Spring Modifier, the scene should work normally. Spring Modi...

Any chance you could post a quick hip file that demonstrates the problem?

If you've just recently upgraded to Houdini 19, my guess is that you're using a Python 2 build of MOPs Plus. Try installing a Python 3 build and see if that works better. Let me know if it works!

That's certainly a possibility, but unfortunately I can't help you with that. You could always try installing an Apprentice / non-commercial license and see if that works better for you.

You can't "delete" a shelf by closing it... you just need to add it back to your list of active shelves from the "+" button on the right of the shelf panel. Regarding the errors you're seeing, my guess is that you're using a Python 2 version of MOPs Plus with a Python 3 version of Houdini, or vice v...

Hahaha, honest mistake. That .hip file header error still seems strange, though-- if you didn't have MOPs installed, what should happen is the file will tell you that there are missing definitions, not that the header itself is not found. Try downloading the .hip files using that button I showed you...
