Hi people. I would like know is it possible to make moving clouds to move around on the sky when battling ?

Sounds intereting. Do you guys know any shader/shaders what would do it possible ?

It's pretty easy, you have various textures which act as layers, a pair will suffice.
Then on the pixel shader you mix them and add a slight horizontal scrolling in the UV coordinates of the top layer by using the
Code:
time_varFancier effects are common, but something like that will look fine enough for the untrained eye.
It requires some changes to the existing skybox shader, its in-brf shader reference and possible materials.

Edit: Something like this, pseudo-code, untested.
Code:
...
/* sample both textures in their respective coordinates, the second texture needs to be transparent */
float3 cloud_background = text2d(diffuse_sampler, uv).rgb;
float4 cloud_foreground = text2d(diffuse_sampler2, float2(u.x + (time_var*.4), v.y));
/* blend them using linear interpolation, modulating by the moving clouds alpha/transparency channel */
float3 final_color = lerp(cloud_background.rgb, cloud_foreground.rgb, cloud_foreground.a);

Or by particules method 
1 make a simple model with the good material (import in open brf) name it "prt_mesh_anim_clouds".
2 a clouds texture with 50% transparency ,save it in dxt5
3 the codes :
module_scene_props
module_particle_systems
On the scene : edit mode/put an animated cloud.
The same method used by my animated fog /and birds
Take my cloud texture if you want in pgn > you need to make :50% or less/much transparency/save in DXT5

Thanks a lot for both of you of your efforts, This will go to good use.
