MOPs Forums

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....

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...

Glad to hear it! Have fun with MOPs, and if you need help, feel free to ask here or on our Discord server.

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.

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...

The command is just to see what value is returned. I'm trying to make sure that the MOPs directory is actually being added to your HOUDINI_PATH. You don't need to restart... just hit enter after entering each of those commands, and show me what comes back.

Okay. From within Houdini, go to the Python shell (ALT+SHIFT+P) and enter the following, one at a time: import os print(os.getenv("HOUDINI_PATH")) Then show me the result of this command. Alternatively, if you'd like me to help you via video chat, please email me at henry@motionoperators.com and I'l...

Weird. Can you please try temporarily removing your houdini.env file and see if MOPs loads correctly?

Okay, so that HOUDINI_PATH declaration is overwriting anything that the package file is doing.

You just need to add $HOUDINI_PATH; to the beginning of the HOUDINI_PATH declaration, similar to what's already being done with $PATH on the previous line.

Okay, that looks right. Can you please also show the contents of your Houdini.env file?
