Animated texture without a sprite sheet or code.

While I worked at a game company using DirectX 11 I was able to animate a fire texture by simply stretching the image past the UV bounds. This was some time ago and their engine was proprietary and my recent attempt to reproduce the effect has been fruitless. I know this can be done through code or a sprite sheet, however this is supposed to be a simple effect in the background with the image basically scrolling on the polygon. Also changing the vertex alphas allowed the edges of the polygon to fade.

If anyone has anything on how this was accomplished or if Unity can do this let me know. I am using Max 2016 and Unity.

 

Well, you can write a (surface) shader and use builtin _Time vairable. You'll still need to write a shader, but that won't be a C# code.

 

So the scrolling isn't something that is built into the directx shader in max or the built in shaders in unity? Also, I don't understand what you mean by write a shader. Can you explain or direct me to writing a surface shader?

You can just move the UV coordinates on the mesh.

As another alternative you can offset the texture.

 

Yea, if you aren't familiar with shaders and don't want to code, do this, and you can animate the values with the animator.
