If you can't see any available Python 3.11 builds, it's possible your subscription lapsed before July 2024? Python 3.11 compatibility was added to MOPs Plus shortly after Houdini 20.5 released, on 2024-07-10. You're only entitled to download builds released within one year of your last subscription ...

This error is usually caused by a Python version mismatch. Make sure that the Python version for MOPs Plus matches the version of Python you're using in Houdini (for 20.5 it's typically 3.11).

Okay, please try updating to MOPs 1.9.2 Experimental. This patch should address the bug you're seeing.

Yep, this looks like a bug in the Noise Modifier. The pieces moving as blocks in MOPs_Noise_Modifier1 are because of the chosen noise patten (Mosaic), if you run a different noise they'll move independently. The direction is still world space and should be local space, though. I'll have a patch out ...

If you know the axes that you want to rotate around but the packed primitives aren't currently aligned to those axes, you can use MOPs Reorient to override the existing local axes of each piece. Just create that `v@rotaxis` attribute and then set that as the N vector for MOPs Reorient and any rotati...

I'm still not entirely sure this is what you're asking for, but are you trying to align the objects to the deformation as if it were a surface? This would be a lot easier if you actually had a surface to adhere to, but there's a little trick you can use in this case because you have that nice smooth...

Hey there, There's two ways you could handle this. For rotating around the bounding box centroid, the easiest way is to just use a Transform SOP with $CEX $CEY and $CEZ as the pivot... it'll transform everything around the centroid, including rotation. The other way to go is to use MOPs Pivot. You c...

Sorry about the trouble... not sure why you were having trouble contacting me, my email address is posted all over the place including on my account profile here.

I'll handle removing your account ASAP.

Based on your scene, what you'd want to do is use the Redshift Proxy Output SOP to write your plant sequences to disk as .rs files, then load them back in using the Redshift Packed Proxy SOP. Copy those to points using the variants workflow you already have in place, then use MOPs Set Sequence Time ...
