View Full Version : Texture displacement

How do I create a ripple displacement on a flat object, at a specific spot...like something falling through the displacement object and causing the disturbance?

At the moment I'm playing with a null as the reference object under the texture displacement properties. It's not doing what I want. The texture stays static even when I move the null.

U are in the right way...
Try this settings (my plane is 10X10 m)

And here is FallOff settings and moved ref Null...
Have fun :)

Thanks Eugeny

hmmm, must be doing something els wrong then. With the same settings I get something diferent. The ripple doesn't even follow the null.

question - Should I set the sub-d order to last?
question 2 - Are you using the "displacement map" thingy under the Deform tab, or are you adding a "Texture Displacement" under "Add Displacement"

This is what I get. hehehe As you can see, I moved the null
but the ripple stays in the middle...also the ripple looks more like a star displacement effect.

Eugeny, Thanks for the help man. I appreciate it! I got the ripple to look cool, and move when I move the null. The only problem now is that I have to move the null faaaaaaaar away from the object befor the ripple bigins to move. How do I fix this?

Use Ripples2 instead of Ripples...
Also change the Wave length (like in settings in prew my post - the diff settings is too small) use only one wave source.
It's mast work...
:shrug:

Did u scaled your object?
Also define ref null in his rest position (0.0.0) and then move...
I use Displacement Map with T button.
The object is good density mesh with sub patch 3 - after displacement. If u use First u get "spiky effect" so u need to add sub patch level ...

Argh!!! yeah it works! I scaled the damn object before I put the displacement map on. That is why I need to move the Null far away from the object before the displacement moves.

Thanks again!

Eugeny.......I think we just found your first tutorial :beer:

Let me know if your up to creating a basic tutorial fo rthis....I think that Newbies could really benifit from this.....Thanx in advance.

Werner

Yeah Eugeny, I think proton has a point!

I have another question regarding this. How would you go about adding more nulls to the same surface...you know, so you can move both and they deform the same object?

Eugeny

Proton u can simple use this as template for tut...
Anyway my english is too poor to write tutorials :)

Werner

not to worry...I just added another null and another texture layer to the displacement map...it does the trick!

Man, I love Lightwave more and more each day!

WilliamVaughan
