Help creating Ooze background

Hello guys,

I need to create an ooze/gel/slime looking texture for our game. It needs to move, so just a picture won't exactly do. It's going to work as a sort of background. What would you suggest? I'm trying a simple daylight water with different colors and setting the wave speeds to "slow numbers" but I'm wondering if there might be a way to make it look better.

I found this picture that sort of showcases what we want


Thanks.

Why not use an image sequence?

Code (csharp):

1. var images : Texture2D[];
2. var frameDelay = 0.2;
3. var mat : Material;
4. private var index = 0;
5.  
6. function Start ()
7. {
8.      while (true)
9.      {
10.           mat.mainTexture = images [index];
11.           ++index;
12.           index = Mathf.Repeat (index, images.length);
13.           yield WaitForSeconds (frameDelay);
14.      }
15. }

Hey thank you very much. This would work great.

How CPU intensive would it be though?

 

None, but it would be very RAM-intensive.

Should I use something else then? It's going to be an iPhone game.

 

Yes, I would say so. You could do what you said originally, but use multiple layers for a parallax effect, though that would have issues with overdraw. I might be inclined to use a tessellated mesh and animate the vertices in a waving pattern.

Gaining RAM but sacrificing CPU right?

I'd need to do some research for that, mind pointing me in the right direction please? Just getting started with Unity heh.

 

Not actually CPU, since you can do that in a shader. Or you could use the Mesh class.

Haven't learned to write shaders yet. I'll do research for the Mesh class. That plus what you mentioned above might work. I'll see how performance goes with image sequences first.

Thank you very much.

Very great shader.
