UV shifting on model texture ?

[YouGroove]

Like that lava :

 

It is possible on models, i dind't find it on documentation ?

This can be easily done with a shader. Declare a uniform in the fragment shader like this:

uniform float currenttime;

 

Then use that to modify your texture coordinates:

texcoords.y += currenttime/100.0;

Sorry I'm trying to get this working and I'm a shader noob which is a bad combo....

 

 

//Uniforms
uniform sampler2D texture0;//diffuse map
uniform float currenttime;

//Inputs
varying vec2 ex_texcoords0;
varying vec2 ex_texcoords1;
varying vec4 ex_color;
varying float ex_selectionstate;

void main(void)
{

vec2 texcoords = ex_texcoords0;

texcoords.y += currenttime/100.0;

vec4 outcolor = ex_color;

//Modulate blend with diffuse map
outcolor *= texture2D(texture0,ex_texcoords0);

//Blend with selection color if selected
gl_FragColor = outcolor;
}

 

Obviously it's not working, am I on the right track? Any clues on how to get it working? Any help would be appreciated!

 

Cheers!

Just change :

 

outcolor *= texture2D(texture0,ex_texcoords0);

 

to

outcolor *= texture2D(texture0,texcoords);

F^ yeah! Thanks Shadmar!
