A Matrix Ripple VFX

I want to make a special effect in my game where it makes a Matrix Ripple to the background, similar to helicopter scene in The Matrix where it smashes against the building and creates that ripple effect.

How would I go about doing this?

Hi,
There is more ripple fx shader here , you can choise one of them and after that port this to fusion ;
Please login to see this link.

Thank you.

How do you import it into Fusion? Just copy the code over?

From what I figured I make an active object then go to Properties - Effect and then Lens?

And then from Lens to the Editor and copy the code from the browser to the effect editor under FX file or XML file?

Never done this before so figuring it as I go.

Hi, after you choose the shader than you must write shader to dx9 or dx11 for fusion ,
what is the shader you want to convert from shadertoy let me the url please , i can see if it's can doable for fusion ?
thanks

I chose this one: Please login to see this link.

Here's an example using the lens shader

Thank you. Imma check it out and see what I can do with it.

I have jus tryed to adapt this shader first time to DX9 ;

so ; the xml file : Shockwave.xml is like so ;

After the two files are saved;
create windows project for DX9 and insert ACTIVe object with image texture
do that on event ;

every 0.05 sec change effect parameter t_timer to timer*0.0002
and run the project normally the ripple fx is working;

Thank you, lemme try this.

You could use this with some tweaking. Add the Lens object to distort the building.

I will take a look at it. Thank you!

Can you make this into an mfa for me?
