Re: Mops and Pops orientation

The MOPs Instancer doesn't automatically use velocity as the N or "forward" attribute when instancing to points. If you want your points to aim in the direction of motion, define a normal attribute from your velocity. You can do it really quickly with a Point Wrangle on your particles: v@N = normali...

Re: MOPs_Visualize_Frame not showing binormal axis

Ah, I probably need to update the example file to use the latest node definitions. Thanks for bringing it to my attention!

Update: This is now fixed.

Re: MOPs_Visualize_Frame not showing binormal axis

The attributes used by MOPs Visualize Frame are supposed to be temporary; you don't actually need a binormal attribute. MOPs derives this from the other template or intrinsic transform attributes. If you're not seeing one of the axes, that's a different problem. What version of Houdini and MOPs are ...

Common MOPs and MOPs Plus Issues

I don't see MOPs when I boot up Houdini! First of all, check the wiki for detailed install instructions: https://github.com/toadstorm/MOPS/wiki/Installation Please consider using the package (JSON) method to install; it's way simpler. The MOPS variable should point to the directory where you placed...

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...

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

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.
