Feature Request: Vertical Simple Shapes

[Mohawk20]

Sometimes a mask with a gradient might be needed.
For example in my waterfall scene (see image below), I curved the top to simulate realistic physics.
I wanted to use a vertical simple shape for best control over the curve, but couldn't. So i had to use a painted shader, which took a lot of work to tweak.

Is there a chance all axis-rotation for simple shapes could be implemented?

If I'm not mistaken, you can rotate a Simple Shape. I believe this is how I did 2d flames.

I don't know how you pulled this off with the painted shader, hats of for that anyway, I never use that shader.

If the waterfall is a ribbon shaped plane object which you displaced to create the curve then I don't really understand the problem I'm afraid.
In that case I would position the plane object at the top of the waterfall and have it extend horizontally over the edge.
Then displace that plane down with a simple shape shader's color as input for a (vector) displacement shader.
To make the falloff non-linear you would need to position a colour adjust or bias scalar in between the simple shape and displacement shader.
That should give you enough control for the curvature.

Must have been in 3D space. It's pretty handy actually. Just a little annoying to use... especially if you hit the edges while it's rendering preview, and paints/erases the whole viewport. It honestly should pause when you start painting and wait you to stop painting. I pause manually when RTP is finished. Then paint.

You can rotate SSS's alright.

And warp them!

So if I place a simple shape at the top of the waterfall (which is a plane), I should be able to rotate it on the z-axis and set the displacement in such a way that the top of the plane curves backwards toward the cliff?
Because in the simple shape settings itself you can only rotate the shape on the y-axis, and a transform shader doesn't seem to do anything either.

I think you need world space checked in the transform.

Yes, see example.

Yes, see example.

Well, that doesn't give the results I would like.

I want the top of of a plane curving backwards.

I changed the setup in your file to match my setup, with unsatisfying results:

[Dune]

Then you probably need to apply a soft SSS mask to the top and redirect or vdisp the plane. Or a distribution shader with min altitude set.

Probably.
Distribution shader would do the trick I guess.

But it does mean some more flexibility within the sss would definitely be useful.

Yes, I was thinking lately that some rotating handles and/or sliders in all directions would be good.

yup....thought that as well.
