Vertical water plane -> Waterfall (+animation)

Tangled-Universe · February 05, 2009, 03:38:34 PM

Well...isn't the solution quite simple?

Create a Distribution Shader V4, add the watershader with powerfractal as a child layer to the distribution shader. Then plug the powerfractal for the opacity into the blendshader and there you go. You even then have grayscales functioning

That's the reason why I post my problem on these forums. There's always someone with a fresh view on the case.
I'm gonna try that right away...

On the other hand..
If you replace opacity with blending you have a problem.
What disappeared when using opacity just remains black if using blending.
So instead of erasing pieces of waterfall, we would be adding pieces of simple plane into the waterfall.

Haha, well that is just how you look at blending

In photoshop you can add a layer mask set to "reveal all" or "hide all"...so you can either mask to reveal stuff or to hide it. It's just how you look at it, but you're right

Well, TG isn't PhotoShop, and I was talking TG... (I know PhotoShop can blend better).
Even though I don't expect it to work, I'm still rendering with the setup you suggested.
Let's see what happens.

If it doesn't work, does anyone else have any ideas?

Of course, I just meant to explain different ways of thinking

Looking forward to see the result. Can't think so fast about a reason why it won't work. It offers everything you need.

I suggest you try for yourself, because the result I get is nothing to write home about...
See below. The part circled in red is different, because of the blending shader, but it's still a piece of plane, it should be a piece of sky...

I attached the tgd, so you can take a look for yourself..

Thanks Mo, I'll take a look at it as soon as I'm home and have time.

PS., cool dutch translation

did you ever read the book "I always get my sin?"

Mohawk20 · February 06, 2009, 06:29:01 PM

Any ideas yet?
Below is my last render.
Took a while to get the clouds just right.

It will be the last of this project unless anyone can figure out that opacity thing...

It's still looks pretty good.

I haven't had any time yet to check this out Mohawk, sorry.
I certainly will.
First I have to finish some renderingstuff and tutorial-writing, then install my new hard-drive and then I might be able to give it a go

Hi,
like that?

Mohawk20 · February 07, 2009, 01:42:37 PM

Hmmm, nice orange...

Yes, like that.
I'll take a look at it.
The opacity function should be bigger though, you'd want the lack of water mostly along the edges...

If there's a way to rotate the distribution shader you could have two facing opposite directions.

Mohawk20 · February 07, 2009, 02:46:02 PM

It would be nice to have a two-sided waterfall, but most of the time you only render one side anyway...

PG · February 07, 2009, 04:02:14 PM

No I mean to get the effect of water density dropoff to the edges. use two distribution shaders, facing the same way but rotated so that one performs a dropoff to the left and the other performs the dropoff to the right. maybe I'm thinking of the distance shader applied to a default shader.
