How can I make a River running in LW???

[toonafish]

Hi all
I already tried to make morph (like shockwave method).
I'm using procedurals textures and gradients (incidence).
I wanna insert more river rapids to take a better motion look.

How can I do that?
have anything (plugin or method) that drive my procedural texture to make a curve?

Thanks all

If you want to make the procedurals follow the shape of the curved river the morph-method should work. I don't know what the shockwave method is, but this should work:

Just create a straight river, and create a bent endomorph with tools like bend, rotate, splineguide etc. in modeler.

Or....do a curve extrude with a straight curve, and one with the same settings but a curve in the shape of your river and use background to morph to create a bent endomorph.

Or load a straight river into Layout and bend it with bones, curve-conform, or any other tool and save the shape as an endomorph, or just use it as it is. The texture will also follow the curved shape of the river if it's deformed with bones or another deformer instead of an endomorph.

When you then morph the straight river into the curved one, the procedural texture should follow the shape of the river, just don't use World Coordinates in the texture settings.

To animate it you could add a reference null.

Another way would be to create a UVmap of the straight shape and deform the river to the curved shape.
-load it into Layout and add an empty white or black image in the image editor.
-Add the "textured filter" to the image in the processing Tab with a procedural texture.
-use this image in the surface slots of the river and use the "animation UV cycler" to animate the texture along the UV's.

To make things even more complicated ;-)
You can also animate the procedural texture in the "textured filter" in the image editor slot with either a reference Null or by adding an envelope if you activate the "animate filters" feature. But this will slowdown Layout a lot.

personaly I'd stick with the endomorphs and a reference Null because you'll have more control.

hmm, I think I got carried away a bit :-)

Thanks so much Toonafish.

Exactly!! this morph method is like you said, but I did and didn't work. I don't have sure what's going wrong, I'll try to do some teste with another textures. Look below. what I got with morph method.

This is my first image. need a better motion (river rapids)

I need it

And here a animatedgif of morph.

why not use hypervoxels...

hahahahahahahahahahahahahahahahahahahahahahahahahaha

sry...

I'm not sure what's going on here. I also noticed your thread at Newtek so I know world coorditates are off.

What might be the case is that the texture is stretching because the polygons in the endomorph are stretched. When the points in the endomorph are further apart in certain spots the texture will stretch.

Think of this trick as a poor man's UV's. The points in the straight river are the UV's, so when the distance between the poins on the bent shape is too far off from those on teh straight shape, you'll notice stretching.

I might be completely off, but look at the image I attached. I think that might be what's happening here.

is this what you're looking for ?

[MorBioS]

hummm... It's possible. Really, my straight river is not uniform distribute of vertex.

I'll try to distribute better vertex along straight river.


Thanks Toonafish


Tomorrow I'll try and come back to show the result

Thanks all

Hi All.


Finally works fine here. http://www.newtek.com/forums/images/smilies/smile.gif

As Toonafish said the problem was distribution of points. I did make another object based in a simple geometry and texture works fine. http://www.newtek.com/forums/images/smilies/smile.gif

Thanks so much for you guys http://www.newtek.com/forums/images/smilies/smile.gif http://www.newtek.com/forums/images/smilies/brians/023.gif

Hey look here (http://www.lumentechnology.com.br/valter/river.gif) my result

nice results!
