so i have a cloud bitmap and an alpha im going to use in the skybox but i want it to animate a little bit. like take the still jpeg picture of a cloud and i want it to move like clouds with a cloudy grainy texture overlay. is there anyway i can make a shader do this?

would love to have help with this.

also id like anyone who hasent already seen it please take the time to look at the map i released recently http://hce.halomaps.org/index.cfm?fid=6090 its a "true" BLOOD gulch. anyways. thanks in advance

The clouds in clear_afternoon sky scroll/move.
Look at the 2d texture animation section within the 4 stage maps section of sky/clear_afternoon/shaders/sky clear blue.shader_transparent_chicago_extended

ok so i dont want them to move at all around the skybox. but i realised something that might be helpful. basically my bitmap needs to stay still but have stationary clowd movement. and i need the diffuse to have multiple colors that is blended into the sky usigng the alpha. like a distant explosion way off in the distance. anyways i know how the small red and blue teleporters in extinction, (and plenty of other maps) has a genaric bitmap for the rectangle and the light, but there are clouds inside that disapear when they go out of the alpha.. im thinking that something like that might help. sortof make alpha white have the clowds in a layer. im not sure how to go about making this and . if this is possible this might be just what im asking for. anyone know how to go about this?
