Re: Move Along Curve Falloff Issue

Hi there, This is an ancient tutorial and not at all indicative of the current tools, as you've seen. If you want to see some examples of how you can use Move Along Spline, I'd recommend checking out the example file "move_along_spline_1.5.hip" that's included in the installation. The key parameters...

Re: MOPS_Transform unexpected behavior

MOPs Plus isn't yet compatible with Python 3.9. To use Plus with Houdini 19.5, install a Python 3.7 build of Houdini 19.5 and it should work.

Re: How to read point attrs in MOPs Transform Modifier's vexpression?

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. ...

Re: Can I load a scene with MOPS nodes into a Houdini without MOPS installed?

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.

Re: Issue using two spring modifiers

The Spring Modifier is freaking out in this case because on the first frame of the simulation, there aren't any objects due to the Blast SOP deleting all points greater than the falloff threshold. If you move that Blast to after the second Spring Modifier, the scene should work normally. Spring Modi...

Re: camera blender causing Segmentation fault

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!

Re: Why can't Houdini open the hip file of github?

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.
