Right now I'm creating a watery surface with this, which I found on something or other that I downloaded.

And it mosty looks pretty good where something is reflecting in the water. Kind of flat otherwise. So I've been looking at the wave3d node but I don't know how to use it, most especially how to connect it. I'm thinking I can create wave effects, maybe ripple effects. Hopefully that's what it does!

Can I buy a clue? Okay, maybe just have one for free?

I imagine you want to do an animation about waves.    Here is a YouTube link to how this individual managed it.

Poser Tutorial Water / Wave Animation (youtube.com)

I haven't come across any tutorial on using the wave3d node. 

You again??

(Just Kidding)

Actually, I'm trying to set up still images, not animations. I did some animations back 20 years ago but they were pretty crude and it seems to not be my thing. For me, mostly Poser is "just" a digital implementation of a fantastic photo studio. Enormous studio, lots of props, and models who can hold a pose forever.

Right now, for a water surface, I'm using the water that came with The Great Lake prop which came with Poser. I think. It does nice reflections. And I'm trying to make it more realistic. Like adding wavelets or swells. And, especially, ripples around something penetrating or touching the water. For that I've tried using the morph tool but with limited success. So, you got me exploring some of the more exotic (to me, at least) material nodes, and I stumbled across wave3d. Sounds good but a) I haven't figured out how to incorporate it and b) I read recently that it has a major flaw in that its minimum wave frequency grows as the underlying surface grows and makes it useless for larger bodies of water.

But -- thank you for the link! I have saved it for later consumption.

Hey, totally off-topic but while I have your attention, I'm working on a prop made from the standard hires cube. It has "openable" windows on all six surfaces. Like this:

With, ultimately, a parameter group like this:

Only Open Front is working now, although I do have the needed dials from the material room animated, so they're available from Cube_1. I just need to create and setup the connections from them to the dials in the Windows group.

So, my question is really two.

Would anyone else find this useful, you think? 

If so, what's the best way for sharing it?

There is usually some individual who might find it useful.  The best way to share it is in the Freebie section.  It must be submitted as a zip file in the proper folder hierarchy for Poser.  Otherwise, installation will be a nightmare for inexperienced users.

Thank you. I will do that.

Well, damn. Again, after slaving away (and finally getting it to work), I realize that I've done it the hard way. No longer does it seem impressive, although doing it the hard way, by animating dials in the materials room, was instructive. Now I'm just creating props from The Grouping Tool, animating the Visible property, and the rest is probably completely obvious.

Thank you for putting up with my ignorance. I *am* learning.

Nothing wrong with that.  You will find that there are multiple ways to accomplish the same thing, it's a matter of finding the most convenient and efficient way of doing it.
