MOPs Forums

Hey everyone,

The MOPs Forums had a bit of a technical glitch and I had to restore them from a backup. This means that any posts made in the last 4 days or so may have been erased. Sorry about that!

One other thing I should mention: when time delaying animated sequences, never trust the viewport . It will lie to you about timing. The only way to be certain is to either unpack or render a frame and verify that the delay is happening as expected. This is some kind of Houdini viewport bug that I u...

Hey there, The issue here is that MOPs Delay can only delay the transformation of packed primitives, the time index of packed sequences, or the individual points of an animated polygon mesh. You're trying to delay animation that's been done in SOPs and *then* packed by the Instancer, and MOPs Delay ...

Yep, that sounds right. I think those noise functions don't accept a fourth input. Glad to hear it's working!

Just to be certain, did you download the latest experimental build? You need to either switch from the master branch to the experimental branch on GitHub, or use the MOPs Updater shelf tool to grab the Experimental branch. It should be v1.1.18.

If you enable "Time Varying" on the Noise Falloff or Noise Modifier, there should be a parameter enabled called "Looping Noise". You can then set the Period parameter to determine how many seconds it takes for a full cycle.

Anytime! Let me know if it works for you; I haven't really tested the hell out of it just yet but as long as you don't animate the Offset parameters of the noise, it should loop seamlessly for any noise that supports 4-dimensional inputs (most of them aside from sparse convolution I think?)

Hello,

I probably need to make the error a little more descriptive. The problem is that the sphere that you're trying to transfer an orientation from, does not have an orient attribute. Try wiring a MOPs Orient Mesh onto the sphere before connecting it to MOPs Reorient.

I just added preliminary support for looping noise in the latest Experimental build:

Feel free to give it a shot if you don't want to do it manually.

Hey Mike, Looping noise is definitely possible... what you want are two identical copies of the same noise operation, offset in time. You then ping-pong back and forth on the "weight" between the two noise patterns so that noise2, which is time offset by say, four seconds, has a weight of 1.0 at fou...
