Re: Offset growth animation with falloff and Set Time Sequence

I'm not an Octane expert, but according to https://render.otoy.com/forum/viewtopic ... 01&t=76202 it's possible to directly instance bgeo files using the instancefile attribute, which MOPs supports.

Re: mops randomize and mops transform modifier doesn't work

The reason this isn't working is a little tricky... you're trying to randomize the mops_falloff attribute, but you also have "Enable Falloff" toggled on and there's no incoming falloff attribute to speak of! In this specific case, MOPs Randomize doesn't automatically initialize a falloff attribute f...

Re: mops randomize and mops transform modifier doesn't work

It looks like you have "Ignore zero falloff prims" enabled. If you don't have a falloff attribute upstream and this toggle is enabled, MOPs nodes will have no effect.

If that doesn't help, could you upload your hip file so I can take a look?

Re: Combining falloffs

There is a MOPs Combine Falloffs SOP with several included blend modes that should do exactly what you need.

Every Falloff node actually has one of these internally. If you chain two Falloff nodes you can just set the blend mode on the second one to combine them.

Re: mops_Set_Sequence_Time

Are you able to post the hip file in question? It's hard to diagnose the problem from just a screenshot.

If you can't zip and attach it here publicly, you can email it to me personally: henry@motionoperators.com

Re: Scatter polygons on a terrain using the MOPs Instancer node

Here's your file back. This is what I had in mind when I was telling you to try instancing clumps of grass rather than individual blades. I animated the clumps using procedural noise instead of Vellum, then cached the animation to disk and instanced them on the heightfield as a Packed Disk Sequence....

Re: Scatter polygons on a terrain using the MOPs Instancer node

This scene file doesn't include any attempt at instancing or copying to points, so I'm just guessing at what you're going for exactly. My advice would be to simulate a clump of grass rather than a single blade, and then cache that simulation to disk via Alembic output. You'd then load that Alembic f...

Re: Installing MOP

Please email me at henry@motionoperators.com so we can schedule a video call. I'm going to need to look at your system live so that I can figure out why the directory isn't updating.

Re: Installing MOP

Now that's interesting! See how it's adding "C:/Users/Henry/Projects/VFX/MOPS" to your HOUDINI_PATH? That means that the package file you saved isn't the one being read. Did you happen to copy that original package file anywhere else on your drive? Maybe somewhere in the Houdini installation directo...
